# eBPF monitoring with Netdata
-eBPF consists of a wide toolchain that ultimately outputs a set of bytecode that will run inside the eBPF virtual
-machine (VM) which lives inside the Linux kernel. The program in particular is executed in response to a [tracepoint
-or kprobe](#probes-and-tracepoints) activation.
+The Netdata Agent provides many [eBPF](https://ebpf.io/what-is-ebpf/) programs to help you troubleshoot and debug how applications interact with the Linux kernel. The `ebpf.plugin` uses [tracepoints, trampoline, and2 kprobes](#data-collection) to collect a wide array of high value data about the host that would otherwise be impossible to capture.
-Netdata has written many eBPF programs, which, when compiled and integrated into the Netdata Agent, are able to collect
-a wide array of data about the host that would otherwise be impossible. The data eBPF programs can collect is truly unique,
-which gives the Netdata Agent access to data that is high value but normally hard to capture.
+> ❗ eBPF monitoring only works on Linux systems and with specific Linux kernels, including all kernels newer than `4.11.0`, and all kernels on CentOS 7.6 or later. For kernels older than `4.11.0`, improved support is in active development.

-## Probes and Tracepoints
+<a id="data-collection"> </a>
-The following two features from the Linux kernel are used by Netdata to run eBPF programs:
+## How Netdata collects data using probes and tracepoints
-- Kprobes and return probes (kretprobe): Probes can insert virtually into any kernel instruction. When eBPF runs in
- `entry` mode, it attaches only `kprobes` for internal functions monitoring calls and some arguments every time a
- function is called. The user can also change configuration to use [`return`](#global) mode, and this will allow users
- to monitor return from these functions and detect possible failures.
-- Tracepoints are hooks to call specific functions. Tracepoints are more stable than `kprobes` and are preferred when
- both options are available.
+Netdata uses the following features from the Linux kernel to run eBPF programs:
-In each case, wherever a normal kprobe, kretprobe, or tracepoint would have run its hook function, an eBPF program is
-run instead, performing various collection logic before letting the kernel continue its normal control flow.
+- Tracepoints are hooks to call specific functions. Tracepoints are more stable than `kprobes` and are preferred when
+ both options are available.
+- Trampolines are bridges between kernel functions, and BPF programs. Netdata uses them by default whenever available.
+- Kprobes and return probes (`kretprobe`): Probes can insert virtually into any kernel instruction. When eBPF runs in `entry` mode, it attaches only `kprobes` for internal functions monitoring calls and some arguments every time a function is called. The user can also change configuration to use [`return`](#global) mode, and this will allow users to monitor return from these functions and detect possible failures.
-There are more methods by which eBPF programs can be triggered but which are not currently supported, such as via uprobes
-which allow hooking into arbitrary user-space functions in a similar manner to kprobes.
+In each case, wherever a normal kprobe, kretprobe, or tracepoint would have run its hook function, an eBPF program is run instead, performing various collection logic before letting the kernel continue its normal control flow.
-## Manually enable the collector on Linux
+There are more methods to trigger eBPF programs, such as uprobes, but currently are not supported.
-**The eBPF collector is installed and enabled by default on most new installations of the Agent**. The eBPF collector
-does not currently work with [static build installations](/packaging/installer/methods/kickstart.md#static-builds) for kernels older
-than `4.11`, but improved support is in active development.
+## Configuring ebpf.plugin
-eBPF monitoring only works on Linux systems and with specific Linux kernels, including all kernels newer than `4.11.0`,
-and all kernels on CentOS 7.6 or later.
+The eBPF collector is installed and enabled by default on most new installations of the Agent.
+If your Agent is v1.22 or older, you may to enable the collector yourself.
-If your Agent is v1.22 or older, you may to enable the collector yourself. See the [configuration](#configuration)
-section for details.
+### Enable the eBPF collector
+
+To enable or disable the entire eBPF collector:
+
+1. Navigate to the [Netdata config directory](/docs/configure/nodes.md#the-netdata-config-directory).
+ ```bash
+ cd /etc/netdata
+ ```
+
+2. Use the [`edit-config`](/docs/configure/nodes.md#use-edit-config-to-edit-configuration-files) script to edit `netdata.conf`.
+
+ ```bash
+ ./edit-config netdata.conf
+ ```
+
+3. Enable the collector by scrolling down to the `[plugins]` section. Uncomment the line `ebpf` (not
+ `ebpf_process`) and set it to `yes`.
+
+ ```conf
+ [plugins]
+ ebpf = yes
+ ```
+
+### Configure the eBPF collector
+
+You can configure the eBPF collector's behavior to fine-tune which metrics you receive and [optimize performance]\(#performance opimization).
+
+To edit the `ebpf.d.conf`:
+
+1. Navigate to the [Netdata config directory](/docs/configure/nodes.md#the-netdata-config-directory).
+ ```bash
+ cd /etc/netdata
+ ```
+2. Use the [`edit-config`](/docs/configure/nodes.md#use-edit-config-to-edit-configuration-files) script to edit [`ebpf.d.conf`](https://github.com/netdata/netdata/blob/master/collectors/ebpf.plugin/ebpf.d.conf).
+
+ ```bash
+ ./edit-config ebpf.d.conf
+ ```
+
+ You can now edit the behavior of the eBPF collector. The following sections describe each configuration option in detail.
+
+### `[global]` configuration options
+
+The `[global]` section defines settings for the whole eBPF collector.
+
+#### eBPF load mode
+
+The collector uses two different eBPF programs. These programs rely on the same functions inside the kernel, but they
+monitor, process, and display different kinds of information.
+
+By default, this plugin uses the `entry` mode. Changing this mode can create significant overhead on your operating
+system, but also offer valuable information if you are developing or debugging software. The `ebpf load mode` option
+accepts the following values:
+
+- `entry`: This is the default mode. In this mode, the eBPF collector only monitors calls for the functions described in
+ the sections above, and does not show charts related to errors.
+- `return`: In the `return` mode, the eBPF collector monitors the same kernel functions as `entry`, but also creates new
+ charts for the return of these functions, such as errors. Monitoring function returns can help in debugging software,
+ such as failing to close file descriptors or creating zombie processes.
+- `update every`: Number of seconds used for eBPF to send data for Netdata.
+- `pid table size`: Defines the maximum number of PIDs stored inside the application hash table.
+
+#### Integration with `apps.plugin`
+
+The eBPF collector also creates charts for each running application through an integration with the
+[`apps.plugin`](/collectors/apps.plugin/README.md). This integration helps you understand how specific applications
+interact with the Linux kernel.
+
+If you want to _disable_ the integration with `apps.plugin` along with the above charts, change the setting `apps` to
+`no`.
+
+```conf
+[global]
+ apps = yes
+```
+
+When the integration is enabled, eBPF collector allocates memory for each process running. The total allocated memory
+has direct relationship with the kernel version. When the eBPF plugin is running on kernels newer than `4.15`, it uses
+per-cpu maps to speed up the update of hash tables. This also implies storing data for the same PID for each processor
+it runs.
+
+#### Integration with `cgroups.plugin`
+
+The eBPF collector also creates charts for each cgroup through an integration with the
+[`cgroups.plugin`](/collectors/cgroups.plugin/README.md). This integration helps you understand how a specific cgroup
+interacts with the Linux kernel.
+
+The integration with `cgroups.plugin` is disabled by default to avoid creating overhead on your system. If you want to
+_enable_ the integration with `cgroups.plugin`, change the `cgroups` setting to `yes`.
+
+```conf
+[global]
+ cgroups = yes
+```
+
+If you do not need to monitor specific metrics for your `cgroups`, you can enable `cgroups` inside
+`ebpf.d.conf`, and then disable the plugin for a specific `thread` by following the steps in the
+[Configuration](#configuration) section.
+
+#### Integration Dashboard Elements
+
+When an integration is enabled, your dashboard will also show the following cgroups and apps charts using low-level
+Linux metrics:
+
+> Note: The parenthetical accompanying each bulleted item provides the chart name.
+
+- mem
+ - Number of processes killed due out of memory. (`oomkills`)

+### `[ebpf programs]` configuration options
+
+The eBPF collector enables and runs the following eBPF programs by default:
+
+- `fd` : This eBPF program creates charts that show information about calls to open files.
+- `mount`: This eBPF program creates charts that show calls to syscalls mount(2) and umount(2).
+- `shm`: This eBPF program creates charts that show calls to syscalls shmget(2), shmat(2), shmdt(2) and shmctl(2).
+- `sync`: Monitor calls to syscalls sync(2), fsync(2), fdatasync(2), syncfs(2), msync(2), and sync_file_range(2).
+- `network viewer`: This eBPF program creates charts with information about `TCP` and `UDP` functions, including the
+ bandwidth consumed by each.
+- `vfs`: This eBPF program creates charts that show information about VFS (Virtual File System) functions.
+- `process`: This eBPF program creates charts that show information about process life. When in `return` mode, it also
+ creates charts showing errors when these operations are executed.
+- `hardirq`: This eBPF program creates charts that show information about time spent servicing individual hardware
+ interrupt requests (hard IRQs).
+- `softirq`: This eBPF program creates charts that show information about time spent servicing individual software
+ interrupt requests (soft IRQs).
+- `oomkill`: This eBPF program creates a chart that shows OOM kills for all applications recognized via
+ the `apps.plugin` integration. Note that this program will show application charts regardless of whether apps
+ integration is turned on or off.
+
+You can also enable the following eBPF programs:
+
+- `cachestat`: Netdata's eBPF data collector creates charts about the memory page cache. When the integration with
+ [`apps.plugin`](/collectors/apps.plugin/README.md) is enabled, this collector creates charts for the whole host _and_
+ for each application.
+- `dcstat` : This eBPF program creates charts that show information about file access using directory cache. It appends
+ `kprobes` for `lookup_fast()` and `d_lookup()` to identify if files are inside directory cache, outside and files are
+ not found.
+- `disk` : This eBPF program creates charts that show information about disk latency independent of filesystem.
+- `filesystem` : This eBPF program creates charts that show information about some filesystem latency.
+- `swap` : This eBPF program creates charts that show information about swap access.
+- `mdflush`: This eBPF program creates charts that show information about
+ multi-device software flushes.
+
+### Configuring eBPF threads
+
+You can configure each thread of the eBPF data collector. This allows you to overwrite global options defined in `/etc/netdata/ebpf.d.conf` and configure specific options for each thread.
+
+To configure an eBPF thread:
+
+1. Navigate to the [Netdata config directory](/docs/configure/nodes.md#the-netdata-config-directory).
+ ```bash
+ cd /etc/netdata
+ ```
+2. Use the [`edit-config`](/docs/configure/nodes.md#use-edit-config-to-edit-configuration-files) script to edit a thread configuration file. The following configuration files are available:
+
+ - `network.conf`: Configuration for the [`network` thread](#network-configuration). This config file overwrites the global options and also
+ lets you specify which network the eBPF collector monitors.
+ - `process.conf`: Configuration for the [`process` thread](#sync-configuration).
+ - `cachestat.conf`: Configuration for the `cachestat` thread(#filesystem-configuration).
+ - `dcstat.conf`: Configuration for the `dcstat` thread.
+ - `disk.conf`: Configuration for the `disk` thread.
+ - `fd.conf`: Configuration for the `file descriptor` thread.
+ - `filesystem.conf`: Configuration for the `filesystem` thread.
+ - `hardirq.conf`: Configuration for the `hardirq` thread.
+ - `softirq.conf`: Configuration for the `softirq` thread.
+ - `sync.conf`: Configuration for the `sync` thread.
+ - `vfs.conf`: Configuration for the `vfs` thread.
+
+ ```bash
+ ./edit-config FILE.conf
+ ```
+
+### Network configuration
+
+The network configuration has specific options to configure which network(s) the eBPF collector monitors. These options
+are divided in the following sections:
+
+#### `[network connections]`
+
+You can configure the information shown on `outbound` and `inbound` charts with the settings in this section.
+
+```conf
+[network connections]
+ maximum dimensions = 500
+ resolve hostname ips = no
+ ports = 1-1024 !145 !domain
+ hostnames = !example.com
+ ips = !127.0.0.1/8 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 fc00::/7
+```
+
+When you define a `ports` setting, Netdata will collect network metrics for that specific port. For example, if you
+write `ports = 19999`, Netdata will collect only connections for itself. The `hostnames` setting accepts
+[simple patterns](/libnetdata/simple_pattern/README.md). The `ports`, and `ips` settings accept negation (`!`) to deny
+specific values or asterisk alone to define all values.
+
+In the above example, Netdata will collect metrics for all ports between 1 and 443, with the exception of 53 (domain)
+and 145.
+
+The following options are available:
+
+- `ports`: Define the destination ports for Netdata to monitor.
+- `hostnames`: The list of hostnames that can be resolved to an IP address.
+- `ips`: The IP or range of IPs that you want to monitor. You can use IPv4 or IPv6 addresses, use dashes to define a
+ range of IPs, or use CIDR values. By default, only data for private IP addresses is collected, but this can
+ be changed with the `ips` setting.
+
+By default, Netdata displays up to 500 dimensions on network connection charts. If there are more possible dimensions,
+they will be bundled into the `other` dimension. You can increase the number of shown dimensions by changing
+the `maximum dimensions` setting.
+
+The dimensions for the traffic charts are created using the destination IPs of the sockets by default. This can be
+changed setting `resolve hostname ips = yes` and restarting Netdata, after this Netdata will create dimensions using
+the `hostnames` every time that is possible to resolve IPs to their hostnames.
+
+#### `[service name]`
+
+Netdata uses the list of services in `/etc/services` to plot network connection charts. If this file does not contain
+the name for a particular service you use in your infrastructure, you will need to add it to the `[service name]`
+section.
+
+For example, Netdata's default port (`19999`) is not listed in `/etc/services`. To associate that port with the Netdata
+service in network connection charts, and thus see the name of the service instead of its port, define it:
+
+```conf
+[service name]
+ 19999 = Netdata
+```
+
+### Sync configuration
+
+The sync configuration has specific options to disable monitoring for syscalls. All syscalls are monitored by default.
+
+```conf
+[syscalls]
+ sync = yes
+ msync = yes
+ fsync = yes
+ fdatasync = yes
+ syncfs = yes
+ sync_file_range = yes
+```
+
+### Filesystem configuration
+
+The filesystem configuration has specific options to disable monitoring for filesystems; by default, all filesystems are
+monitored.
+
+```conf
+[filesystem]
+ btrfsdist = yes
+ ext4dist = yes
+ nfsdist = yes
+ xfsdist = yes
+ zfsdist = yes
+```
+
+The ebpf program `nfsdist` monitors only `nfs` mount points.
+
+## Troubleshooting
+
+If the eBPF collector does not work, you can troubleshoot it by running the `ebpf.plugin` command and investigating its
+output.
+
+```bash
+cd /usr/libexec/netdata/plugins.d/
+sudo su -s /bin/bash ./ebpf.plugin
+```
+
+You can also use `grep` to search the Agent's `error.log` for messages related to eBPF monitoring.
+
+```bash
+grep -i ebpf /var/log/netdata/error.log
+```
+
+### Confirm kernel compatibility
+
+The eBPF collector only works on Linux systems and with specific Linux kernels. We support all kernels more recent than
+`4.11.0`, and all kernels on CentOS 7.6 or later.
+
+You can run our helper script to determine whether your system can support eBPF monitoring. If it returns no output, your system is ready to compile and run the eBPF collector.
+
+```bash
+curl -sSL https://raw.githubusercontent.com/netdata/kernel-collector/master/tools/check-kernel-config.sh | sudo bash
+```
+
+
+If you see a warning about a missing kernel
+configuration (`KPROBES KPROBES_ON_FTRACE HAVE_KPROBES BPF BPF_SYSCALL BPF_JIT`), you will need to recompile your kernel
+to support this configuration. The process of recompiling Linux kernels varies based on your distribution and version.
+Read the documentation for your system's distribution to learn more about the specific workflow for recompiling the
+kernel, ensuring that you set all the necessary

+- [Slackware](https://docs.slackware.com/howtos:slackware_admin:kernelbuilding)
+
+### Mount `debugfs` and `tracefs`
+
+The eBPF collector also requires both the `tracefs` and `debugfs` filesystems. Try mounting the `tracefs` and `debugfs`
+filesystems using the commands below:
+
+```bash
+sudo mount -t debugfs nodev /sys/kernel/debug
+sudo mount -t tracefs nodev /sys/kernel/tracing
+```
+
+If they are already mounted, you will see an error. You can also configure your system's `/etc/fstab` configuration to
+mount these filesystems on startup. More information can be found in
+the [ftrace documentation](https://www.kernel.org/doc/Documentation/trace/ftrace.txt).

### Memory
In the memory submenu the eBPF plugin creates two submenus **page cache** and **synchronization** with the following
organization:
-* Page Cache
- * Page cache ratio
- * Dirty pages
- * Page cache hits
- * Page cache misses
-* Synchronization
- * File sync
- * Memory map sync
- * File system sync
- * File range sync

+- Synchronization

+ - Memory map sync
+ - File system sync
+ - File range sync
-#### Page cache ratio
+#### Page cache hits
-The chart `cachestat_ratio` shows how processes are accessing page cache. In a normal scenario, we expect values around
-100%, which means that the majority of the work on the machine is processed in memory. To calculate the ratio, Netdata
-attaches `kprobes` for kernel functions:
+When the processor needs to read or write a location in main memory, it checks for a corresponding entry in the page cache.
+ If the entry is there, a page cache hit has occurred and the read is from the cache.
-- `add_to_page_cache_lru`: Page addition.
-- `mark_page_accessed`: Access to cache.
-- `account_page_dirtied`: Dirty (modified) pages.
-- `mark_buffer_dirty`: Writes to page cache.
+A page cache hit is when the page cache is successfully accessed with a read operation. We do not count pages that were
+added relatively recently.
#### Dirty pages
+A "dirty page" is a page in the page cache that was modified after being created. Since non-dirty pages in the page cache
+ have identical copies in secondary storage (e.g. hard disk drive or solid-state drive), discarding and reusing their space
+ is much quicker than paging out application memory, and is often preferred over flushing the dirty pages into secondary storage
+ and reusing their space.
+
On `cachestat_dirties` Netdata demonstrates the number of pages that were modified. This chart shows the number of calls
to the function `mark_buffer_dirty`.

+ (without counting [dirty pages](#dirty-pages) and pages added because of read misses) divided by total access without dirty pages.

-## Configuration
-
-Enable or disable the entire eBPF collector by editing `netdata.conf`.
-
-```bash
-cd /etc/netdata/ # Replace with your Netdata configuration directory, if not /etc/netdata/
-./edit-config netdata.conf
-```
-
-To enable the collector, scroll down to the `[plugins]` section ensure the relevant line references `ebpf` (not
-`ebpf_process`), is uncommented, and is set to `yes`.
-
-```conf
-[plugins]
- ebpf = yes
-```
-
-You can also configure the eBPF collector's behavior by editing `ebpf.d.conf`.
-
-```bash
-cd /etc/netdata/ # Replace with your Netdata configuration directory, if not /etc/netdata/
-./edit-config ebpf.d.conf
-```
-
-### `[global]`
-
-The `[global]` section defines settings for the whole eBPF collector.
-
-#### eBPF load mode
-
-The collector has two different eBPF programs. These programs monitor the same functions inside the kernel, but they
-monitor, process, and display different kinds of information.
-
-By default, this plugin uses the `entry` mode. Changing this mode can create significant overhead on your operating
-system, but also offer valuable information if you are developing or debugging software. The `ebpf load mode` option
-accepts the following values: ​
-
-- `entry`: This is the default mode. In this mode, the eBPF collector only monitors calls for the functions described in
- the sections above, and does not show charts related to errors.
-- `return`: In the `return` mode, the eBPF collector monitors the same kernel functions as `entry`, but also creates new
- charts for the return of these functions, such as errors. Monitoring function returns can help in debugging software,
- such as failing to close file descriptors or creating zombie processes.
-- `update every`: Number of seconds used for eBPF to send data for Netdata.
-- `pid table size`: Defines the maximum number of PIDs stored inside the application hash table.
-
-#### Integration with `apps.plugin`
-
-The eBPF collector also creates charts for each running application through an integration with the
-[`apps.plugin`](/collectors/apps.plugin/README.md). This integration helps you understand how specific applications
-interact with the Linux kernel.
-
-If you want to _disable_ the integration with `apps.plugin` along with the above charts, change the setting `apps` to
-`no`.
-
-```conf
-[global]
- apps = yes
-```
-
-When the integration is enabled, eBPF collector allocates memory for each process running. The total allocated memory
-has direct relationship with the kernel version. When the eBPF plugin is running on kernels newer than `4.15`, it uses
-per-cpu maps to speed up the update of hash tables. This also implies storing data for the same PID for each processor
-it runs.
-
-#### Integration with `cgroups.plugin`
-
-The eBPF collector also creates charts for each cgroup through an integration with the
-[`cgroups.plugin`](/collectors/cgroups.plugin/README.md). This integration helps you understand how a specific cgroup
-interacts with the Linux kernel.
-
-The integration with `cgroups.plugin` is disabled by default to avoid creating overhead on your system. If you want to
-_enable_ the integration with `cgroups.plugin`, change the `cgroups` setting to `yes`.
-
-```conf
-[global]
- cgroups = yes
-```
-
-If you do not need to monitor specific metrics for your `cgroups`, you can enable `cgroups` inside
-`ebpf.d.conf`, and then disable the plugin for a specific `thread` by following the steps in the
-[Configuration](#configuration) section.
-
-#### Integration Dashboard Elements
-
-When an integration is enabled, your dashboard will also show the following cgroups and apps charts using low-level
-Linux metrics:

-### `[ebpf programs]`
-
-The eBPF collector enables and runs the following eBPF programs by default:
-
-- `fd` : This eBPF program creates charts that show information about calls to open files.
-- `mount`: This eBPF program creates charts that show calls to syscalls mount(2) and umount(2).
-- `shm`: This eBPF program creates charts that show calls to syscalls shmget(2), shmat(2), shmdt(2) and shmctl(2).
-- `sync`: Monitor calls to syscalls sync(2), fsync(2), fdatasync(2), syncfs(2), msync(2), and sync_file_range(2).
-- `network viewer`: This eBPF program creates charts with information about `TCP` and `UDP` functions, including the
- bandwidth consumed by each.
-- `vfs`: This eBPF program creates charts that show information about VFS (Virtual File System) functions.
-- `process`: This eBPF program creates charts that show information about process life. When in `return` mode, it also
- creates charts showing errors when these operations are executed.
-- `hardirq`: This eBPF program creates charts that show information about time spent servicing individual hardware
- interrupt requests (hard IRQs).
-- `softirq`: This eBPF program creates charts that show information about time spent servicing individual software
- interrupt requests (soft IRQs).
-- `oomkill`: This eBPF program creates a chart that shows OOM kills for all applications recognized via
- the `apps.plugin` integration. Note that this program will show application charts regardless of whether apps
- integration is turned on or off.
-
-You can also enable the following eBPF programs:
-
-- `cachestat`: Netdata's eBPF data collector creates charts about the memory page cache. When the integration with
- [`apps.plugin`](/collectors/apps.plugin/README.md) is enabled, this collector creates charts for the whole host _and_
- for each application.
-- `dcstat` : This eBPF program creates charts that show information about file access using directory cache. It appends
- `kprobes` for `lookup_fast()` and `d_lookup()` to identify if files are inside directory cache, outside and files are
- not found.
-- `disk` : This eBPF program creates charts that show information about disk latency independent of filesystem.
-- `filesystem` : This eBPF program creates charts that show information about some filesystem latency.
-- `swap` : This eBPF program creates charts that show information about swap access.
-- `mdflush`: This eBPF program creates charts that show information about
- multi-device software flushes.
-
-## Thread configuration
-
-You can configure each thread of the eBPF data collector by editing either the `cachestat.conf`, `process.conf`,
-or `network.conf` files. Use [`edit-config`](/docs/configure/nodes.md) from your Netdata config directory:
-
-```bash
-cd /etc/netdata/ # Replace with your Netdata configuration directory, if not /etc/netdata/
-./edit-config ebpf.d/process.conf
-```
-
-### Configuration files
-
-The following configuration files are available:
-
-- `cachestat.conf`: Configuration for the `cachestat` thread.
-- `dcstat.conf`: Configuration for the `dcstat` thread.
-- `disk.conf`: Configuration for the `disk` thread.
-- `fd.conf`: Configuration for the `file descriptor` thread.
-- `filesystem.conf`: Configuration for the `filesystem` thread.
-- `hardirq.conf`: Configuration for the `hardirq` thread.
-- `process.conf`: Configuration for the `process` thread.
-- `network.conf`: Configuration for the `network viewer` thread. This config file overwrites the global options and also
- lets you specify which network the eBPF collector monitors.
-- `softirq.conf`: Configuration for the `softirq` thread.
-- `sync.conf`: Configuration for the `sync` thread.
-- `vfs.conf`: Configuration for the `vfs` thread.
-
-### Network configuration
-
-The network configuration has specific options to configure which network(s) the eBPF collector monitors. These options
-are divided in the following sections:
-
-#### `[network connections]`
-
-You can configure the information shown on `outbound` and `inbound` charts with the settings in this section.
-
-```conf
-[network connections]
- maximum dimensions = 500
- resolve hostname ips = no
- ports = 1-1024 !145 !domain
- hostnames = !example.com
- ips = !127.0.0.1/8 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 fc00::/7
-```
-
-When you define a `ports` setting, Netdata will collect network metrics for that specific port. For example, if you
-write `ports = 19999`, Netdata will collect only connections for itself. The `hostnames` setting accepts
-[simple patterns](/libnetdata/simple_pattern/README.md). The `ports`, and `ips` settings accept negation (`!`) to deny
-specific values or asterisk alone to define all values.
-
-In the above example, Netdata will collect metrics for all ports between 1 and 443, with the exception of 53 (domain)
-and 145.
-
-The following options are available:
-
-- `ports`: Define the destination ports for Netdata to monitor.
-- `hostnames`: The list of hostnames that can be resolved to an IP address.
-- `ips`: The IP or range of IPs that you want to monitor. You can use IPv4 or IPv6 addresses, use dashes to define a
- range of IPs, or use CIDR values. The default behavior is to only collect data for private IP addresses, but this can
- be changed with the `ips` setting.
-
-By default, Netdata displays up to 500 dimensions on network connection charts. If there are more possible dimensions,
-they will be bundled into the `other` dimension. You can increase the number of shown dimensions by changing
-the `maximum dimensions` setting.
-
-The dimensions for the traffic charts are created using the destination IPs of the sockets by default. This can be
-changed setting `resolve hostname ips = yes` and restarting Netdata, after this Netdata will create dimensions using
-the `hostnames` every time that is possible to resolve IPs to their hostnames.
-
-#### `[service name]`
-
-Netdata uses the list of services in `/etc/services` to plot network connection charts. If this file does not contain
-the name for a particular service you use in your infrastructure, you will need to add it to the `[service name]`
-section.
-
-For example, Netdata's default port (`19999`) is not listed in `/etc/services`. To associate that port with the Netdata
-service in network connection charts, and thus see the name of the service instead of its port, define it:
-
-```conf
-[service name]
- 19999 = Netdata
-```
-
-### Sync configuration
-
-The sync configuration has specific options to disable monitoring for syscalls, as default option all syscalls are
-monitored.
-
-```conf
-[syscalls]
- sync = yes
- msync = yes
- fsync = yes
- fdatasync = yes
- syncfs = yes
- sync_file_range = yes
-```
-
-### Filesystem configuration
-
-The filesystem configuration has specific options to disable monitoring for filesystems, by default all filesystems are
-monitored.
-
-```conf
-[filesystem]
- btrfsdist = yes
- ext4dist = yes
- nfsdist = yes
- xfsdist = yes
- zfsdist = yes
-```
-
-The ebpf program `nfsdist` monitors only `nfs` mount points.
-
-## Troubleshooting
-
-If the eBPF collector does not work, you can troubleshoot it by running the `ebpf.plugin` command and investigating its
-output.
-
-```bash
-cd /usr/libexec/netdata/plugins.d/
-sudo su -s /bin/bash netdata
-./ebpf.plugin
-```
-
-You can also use `grep` to search the Agent's `error.log` for messages related to eBPF monitoring.
-
-```bash
-grep -i ebpf /var/log/netdata/error.log
-```
+- `oom/mark_victim`: Monitors when an oomkill event happens.
-### Confirm kernel compatibility
+## Known issues
-The eBPF collector only works on Linux systems and with specific Linux kernels. We support all kernels more recent than
-`4.11.0`, and all kernels on CentOS 7.6 or later.
-
-You can run our helper script to determine whether your system can support eBPF monitoring.
-
-```bash
-curl -sSL https://raw.githubusercontent.com/netdata/kernel-collector/master/tools/check-kernel-config.sh | sudo bash
-```
-
-If this script returns no output, your system is ready to compile and run the eBPF collector.
-
-If you see a warning about a missing kernel
-configuration (`KPROBES KPROBES_ON_FTRACE HAVE_KPROBES BPF BPF_SYSCALL BPF_JIT`), you will need to recompile your kernel
-to support this configuration. The process of recompiling Linux kernels varies based on your distribution and version.

-### Mount `debugfs` and `tracefs`
-
-The eBPF collector also requires both the `tracefs` and `debugfs` filesystems. Try mounting the `tracefs` and `debugfs`
-filesystems using the commands below:
-
-```bash
-sudo mount -t debugfs nodev /sys/kernel/debug
-sudo mount -t tracefs nodev /sys/kernel/tracing
-```
-
-If they are already mounted, you will see an error. You can also configure your system's `/etc/fstab` configuration to
-mount these filesystems on startup. More information can be found in
-the [ftrace documentation](https://www.kernel.org/doc/Documentation/trace/ftrace.txt).

Metrics that will start having values, after Netdata is started, will be detected and charts will be automatically added to the dashboard (a refresh of the dashboard is needed for them to appear though). Use `yes` instead of `auto` in plugin configuration sections to enable these charts permanently. You can also set the `enable zero metrics` option to `yes` in the `[global]` section which enables charts with zero metrics for all internal Netdata plugins.

-
-Collects metrics from the configured solar power installation from Fronius Symo.
-
-**Requirements**
-
-- Configuration file `fronius.conf` in the node.d Netdata config dir (default: `/etc/netdata/node.d/fronius.conf`)
-- Fronius Symo with network access (http)
-
-It produces per server:
-
-1. **Power**
-
-- Current power input from the grid (positive values), output to the grid (negative values), in W
-- Current power input from the solar panels, in W
-- Current power stored in the accumulator (if present), in W (in theory, untested)
-
-2. **Consumption**
-
-- Local consumption in W
-
-3. **Autonomy**
-
-- Relative autonomy in %. 100 % autonomy means that the solar panels are delivering more power than it is needed by local consumption.
-- Relative self consumption in %. The lower the better
-
-4. **Energy**
-
-- The energy produced during the current day, in kWh
-- The energy produced during the current year, in kWh
-
-5. **Inverter**
-
-- The current power output from the connected inverters, in W, one dimension per inverter. At least one is always present.
-
-## configuration
-
-Sample:
-
-```json
-{
- "enable_autodetect": false,
- "update_every": 5,
- "servers": [
- {
- "name": "Symo",
- "hostname": "symo.ip.or.dns",
- "update_every": 5,
- "api_path": "/solar_api/v1/GetPowerFlowRealtimeData.fcgi"
- }
- ]
-}
-```
-
-If no configuration is given, the module will be disabled. Each `update_every` is optional, the default is `5`.

-[Fronius Symo 8.2](https://www.fronius.com/en/photovoltaics/products/all-products/inverters/fronius-symo/fronius-symo-8-2-3-m)
-
-The plugin has been tested with a single inverter, namely Fronius Symo 8.2-3-M:
-
-- Datalogger version: 240.162630
-- Software version: 3.7.4-6
-- Hardware version: 2.4D
-
-Other products and versions may work, but without any guarantees.
-
-Example Netdata configuration for node.d/fronius.conf. Copy this section to fronius.conf and change name/ip.
-The module supports any number of servers. Sometimes there is a lag when collecting every 3 seconds, so 5 should be okay too. You can modify this per server.
-
-```json
-{
- "enable_autodetect": false,
- "update_every": 5,
- "servers": [
- {
- "name": "solar",
- "hostname": "symo.ip.or.dns",
- "update_every": 5,
- "api_path": "/solar_api/v1/GetPowerFlowRealtimeData.fcgi"
- }
- ]
-}
-```
-
-The output of /solar_api/v1/GetPowerFlowRealtimeData.fcgi looks like this:
-
-```json

-# ISC BIND monitoring with Netdata
-
-Monitor one or more ISC Bind servers.
-
-## Example Netdata charts
-
-Depending on the number of views your bind has, you may get a large number of charts.
-Here this is with just one view:

-
-## How it works
-
-The plugin will execute (from within node.js) the equivalent of:
-
-```sh
-curl "http://localhost:8888/json/v1/server"
-```
-
-Here is a sample of the output this command produces.

-From this output it collects:
-
-- Global Received Requests by IP version (IPv4, IPv6)
-- Global Successful Queries
-- Current Recursive Clients
-- Global Queries by IP Protocol (TCP, UDP)
-- Global Queries Analysis
-- Global Received Updates
-- Global Query Failures
-- Global Query Failures Analysis
-- Other Global Server Statistics
-- Global Incoming Requests by OpCode
-- Global Incoming Requests by Query Type
-- Global Socket Statistics (will only work if the url is `http://127.0.0.1:8888/json/v1`, i.e. without `/server`, but keep in mind this produces a very long output and probably will account for 0.5% CPU overhead alone, per bind server added)
-- Per View Statistics (the following set will be added for each bind view):
- - View, Resolver Active Queries
- - View, Resolver Statistics
- - View, Resolver Round Trip Timings
- - View, Requests by Query Type
-
-## Configuration
-
-The collector (optionally) reads a configuration file named `/etc/netdata/node.d/named.conf`, with the following contents:
-
-```js
-{
- "enable_autodetect": true,
- "update_every": 5,
- "servers": [
- {
- "name": "bind1",
- "url": "http://127.0.0.1:8888/json/v1/server",
- "update_every": 1
- },
- {
- "name": "bind2",
- "url": "http://10.1.2.3:8888/json/v1/server",
- "update_every": 2
- }
- ]
-}
-```
-
-You can add any number of bind servers.
-
-If the configuration file is missing, or the key `enable_autodetect` is `true`, the collector will also attempt to fetch `http://localhost:8888/json/v1/server` which, if successful will be added too.
-
-### XML instead of JSON, from bind
-
-The collector can also accept bind URLs that return XML output. This might required if you cannot have bind 9.10+ with JSON but you have an version of bind that supports XML statistics v3. Check [this](https://www.isc.org/blogs/bind-9-10-statistics-troubleshooting-and-zone-configuration/) for versions supported.
-
-In such cases, use a URL like this:
-
-```sh
-curl "http://localhost:8888/xml/v3/server"
-```
-
-Only `xml` and `v3` has been tested.
-
-Keep in mind though, that XML parsing is done using javascript code, which requires a triple conversion:
-
-1. from XML to JSON using a javascript XML parser (**CPU intensive**),
-2. which is then transformed to emulate the output of the JSON output of bind (**CPU intensive** - and yes the converted JSON from XML is different to the native JSON - even bind produces different names for various attributes),
-3. which is then processed to generate the data for the charts (this will happen even if bind is producing JSON).
-
-In general, expect XML parsing to be 2 to 3 times more CPU intensive than JSON.
-
-**So, if you can use the JSON output of bind, prefer it over XML**. Keep also in mind that even bind will use more CPU when generating XML instead of JSON.
-
-The XML interface of bind is not autodetected.
-You will have to provide the config file `/etc/netdata/node.d/named.conf`, like this:
-
-```js
-{
- "enable_autodetect": false,
- "update_every": 1,
- "servers": [
- {
- "name": "local",
- "url": "http://localhost:8888/xml/v3/server",
- "update_every": 1
- }
- ]
-}
-```
-
-Of course, you can monitor more than one bind servers. Each one can be configured with either JSON or XML output.
-
-## Auto-detection
-
-Auto-detection is controlled by `enable_autodetect` in the config file. The default is enabled, so that if the collector can connect to `http://localhost:8888/json/v1/server` to receive bind statistics, it will automatically enable it.
-
-## Bind (named) configuration
-
-To use this plugin, you have to have bind v9.10+ properly compiled to provide statistics in `JSON` format.
-
-For more information on how to get your bind installation ready, please refer to the [bind statistics channel developer comments](http://jpmens.net/2013/03/18/json-in-bind-9-s-statistics-server/) and to [bind documentation](https://ftp.isc.org/isc/bind/9.10.3/doc/arm/Bv9ARM.ch06.html#statistics) or [bind Knowledge Base article AA-01123](https://kb.isc.org/article/AA-01123/0).
-
-Normally, you will need something like this in your `named.conf`:
-
-```
-statistics-channels {
- inet 127.0.0.1 port 8888 allow { 127.0.0.1; };
- inet ::1 port 8888 allow { ::1; };
-};
-```
-
-(use the IPv4 or IPv6 line depending on what you are using, you can also use both)
-
-Verify it works by running the following command (the collector is written in node.js and will query your bind server directly, but if this command works, the collector should be able to work too):
-
-```sh
-curl "http://localhost:8888/json/v1/server"
-```

-# Stiebel Eltron ISG monitoring with Netdata
-
-Collects metrics from the configured heat pump and hot water installation from Stiebel Eltron ISG web.
-
-**Requirements**
-
-- Configuration file `stiebeleltron.conf` in the node.d Netdata config dir (default: `/etc/netdata/node.d/stiebeleltron.conf`)
-- Stiebel Eltron ISG web with network access (http), without password login
-
-The charts are configurable, however, the provided default configuration collects the following:
-
-1. **General**
-
- - Outside temperature in C
- - Condenser temperature in C
- - Heating circuit pressure in bar
- - Flow rate in l/min
- - Output of water and heat pumps in %
-
-2. **Heating**
-
- - Heat circuit 1 temperature in C (set/actual)
- - Heat circuit 2 temperature in C (set/actual)
- - Flow temperature in C (set/actual)
- - Buffer temperature in C (set/actual)
- - Pre-flow temperature in C
-
-3. **Hot Water**
-
- - Hot water temperature in C (set/actual)
-
-4. **Room Temperature**
-
- - Heat circuit 1 room temperature in C (set/actual)
- - Heat circuit 2 room temperature in C (set/actual)
-
-5. **Electric Reheating**
-
- - Dual Mode Reheating temperature in C (hot water/heating)
-
-6. **Process Data**
-
- - Remaining compressor rest time in s
-
-7. **Runtime**
-
- - Compressor runtime hours (hot water/heating)
- - Reheating runtime hours (reheating 1/reheating 2)
-
-8. **Energy**
-
- - Compressor today in kWh (hot water/heating)
- - Compressor Total in kWh (hot water/heating)
-
-## configuration
-
-If no configuration is given, the module will be disabled. Each `update_every` is optional, the default is `10`.

----
-
-[Stiebel Eltron Heat pump system with ISG](https://www.stiebel-eltron.com/en/home/products-solutions/renewables/controller_energymanagement/internet_servicegateway/isg_web.html)
-
-Original author: BrainDoctor (github)
-
-The module supports any metrics that are parsable with RegEx. There is no API that gives direct access to the values (AFAIK), so the "workaround" is to parse the HTML output of the ISG.
-
-### Testing
-
-This plugin has been tested within the following environment:
-
-- ISG version: 8.5.6
-- MFG version: 12
-- Controller version: 9
-- July (summer time, not much activity)
-- Interface language: English
-- login- and password-less ISG web access (without HTTPS it's useless anyway)
-- Heatpump model: WPL 25 I-2
-- Hot water boiler model: 820 WT 1
-
-So, if the language is set to english, copy the following configuration into `/etc/netdata/node.d/stiebeleltron.conf` and change the `url`s.
-
-In my case, the ISG is relatively slow with responding (at least 1s, but also up to 4s). Collecting metrics every 10s is more than enough for me.
-
-### How to update the config
-
-- The dimensions support variable digits, the default is `1`. Most of the values printed by ISG are using 1 digit, some use 2.
-- The dimensions also support the `multiplier` and `divisor` attributes, however the divisor gets overridden by `digits`, if specified. Default is `1`.
-- The test string for the regex is always the whole HTML output from the url. For each parameter you need to have a regular expression that extracts the value from the HTML source in the first capture group.
- Recommended: [regexr.com](https://regexr.com/) for testing and matching, [freeformatter.com](https://www.freeformatter.com/json-escape.html) for escaping the newly created regex for the JSON config.
-
-The charts are being generated using the configuration below. So if your installation is in another language or has other metrics, just adapt the structure or regexes.

+
+## Requirements
+
+- Asterisk [integrated with StatsD](https://www.asterisk.org/integrating-asterisk-with-statsd/).
+
+## Configuration
+
+Netdata ships
+with [asterisk.conf](https://github.com/netdata/netdata/blob/master/collectors/statsd.plugin/asterisk.conf) with
+preconfigured charts.
+
+To receive Asterisk metrics in Netdata, uncomment the following lines in the `/etc/asterisk/statsd.conf` file:
+
+```ini
+[general]
+enabled = yes ; When set to yes, statsd support is enabled
+server = 127.0.0.1 ; server[:port] of statsd server to use.
+ ; If not specified, the port is 8125
+prefix = asterisk ; Prefix to prepend to all metrics
+```
+
+> See [statsd.conf.sample](https://github.com/asterisk/asterisk/blob/master/configs/samples/statsd.conf.sample) for all available options.

Please note, that by default Netdata will enable monitoring metrics only when they are not zero. If they are constantly zero they are ignored. Metrics that will start having values, after Netdata is started, will be detected and charts will be automatically added to the dashboard (a refresh of the dashboard is needed for them to appear though). Set `yes` for a chart instead of `auto` to enable it permanently. You can also set the `enable zero metrics` option to `yes` in the `[global]` section which enables charts with zero metrics for all internal Netdata plugins.

-This plugin monitors the system clock synchronization state on Linux nodes.
+This plugin monitors the system kernel clock synchronization state.
-This plugin creates two charts:
+This plugin creates the following charts:
-- System clock synchronization state
-- Computed time offset between local system and reference clock
+- System clock synchronization state according to the system kernel
+- System clock status which gives the value of the `time_status` variable in the kernel
+- Computed time offset between local system and reference clock
+
+This is obtained from the information provided by the [ntp_adjtime()](https://man7.org/linux/man-pages/man2/adjtimex.2.html) system call.
+An unsynchronized clock may indicate a hardware clock error, or an issue with UTC synchronization.
