When cgroups are bundled with namespaces (i.e. isolation), they form what we usually call **containers**. - -cgroups are hierarchical, meaning that cgroups can contain child cgroups, which can contain more cgroups, etc. All -accounting is reported (and resource usage limits are applied) also in a hierarchical way. - -To visualize cgroup metrics Netdata provides configuration for cherry picking the cgroups of interest. By default ( -without any configuration) Netdata should pick **systemd services**, all kinds of **containers** (lxc, docker, etc) -and **virtual machines** spawn by managers that register them with cgroups (qemu, libvirt, etc). - -## Configuring Netdata for cgroups - -In general, no additional settings are required. Netdata discovers all available cgroups on the host system and -collects their metrics. - -### How Netdata finds the available cgroups - -Linux exposes resource usage reporting and provides dynamic configuration for cgroups, using virtual files (usually) -under `/sys/fs/cgroup`. Netdata reads `/proc/self/mountinfo` to detect the exact mount point of cgroups. Netdata also -allows manual configuration of this mount point, using these settings: - -```text -[plugin:cgroups] - check for new cgroups every = 10 - path to /sys/fs/cgroup/cpuacct = /sys/fs/cgroup/cpuacct - path to /sys/fs/cgroup/blkio = /sys/fs/cgroup/blkio - path to /sys/fs/cgroup/memory = /sys/fs/cgroup/memory - path to /sys/fs/cgroup/devices = /sys/fs/cgroup/devices -``` - -Netdata rescans these directories for added or removed cgroups every `check for new cgroups every` seconds. - -### Hierarchical search for cgroups - -Since cgroups are hierarchical, for each of the directories shown above, Netdata walks through the subdirectories -recursively searching for cgroups (each subdirectory is another cgroup). - -To provide a sane default for this setting, Netdata uses the following pattern list (patterns starting with `!` give a -negative match and their order is important: the first matching a path will be used): - -```text -[plugin:cgroups] - search for cgroups in subpaths matching = !*/init.scope !*-qemu !/init.scope !/system !/systemd !/user !/user.slice * -``` - -So, we disable checking for **child cgroups** in systemd internal -cgroups ([systemd services are monitored by Netdata](#monitoring-systemd-services)), user cgroups (normally used for -desktop and remote user sessions), qemu virtual machines (child cgroups of virtual machines) and `init.scope`. All -others are enabled. - -### Unified cgroups (cgroups v2) support - -Netdata automatically detects cgroups version. If detection fails Netdata assumes v1. -To switch to v2 manually add: - -```text -[plugin:cgroups] - use unified cgroups = yes - path to unified cgroups = /sys/fs/cgroup -``` - -Unified cgroups use same name pattern matching as v1 cgroups. `cgroup_enable_systemd_services_detailed_memory` is -currently unsupported when using unified cgroups. - -### Enabled cgroups - -To provide a sane default, Netdata uses the -following [pattern list](https://github.com/netdata/netdata/blob/master/libnetdata/simple_pattern/README.md): - -- Checks the pattern against the path of the cgroup - - ```text - [plugin:cgroups] - enable by default cgroups matching = !*/init.scope *.scope !*/vcpu* !*/emulator !*.mount !*.partition !*.service !*.slice !*.swap !*.user !/ !/docker !/libvirt !/lxc !/lxc/*/ns !/lxc/*/ns/* !/machine !/qemu !/system !/systemd !/user * - ``` - -- Checks the pattern against the name of the cgroup (as you see it on the dashboard) - - ```text - [plugin:cgroups] - enable by default cgroups names matching = * - ``` - -Renaming is configured with the following options: - -```text -[plugin:cgroups] - run script to rename cgroups matching = *.scope *docker* *lxc* *qemu* !/ !*.mount !*.partition !*.service !*.slice !*.swap !*.user * - script to get cgroup names = /usr/libexec/netdata/plugins.d/cgroup-name.sh -``` - -The whole point for the additional pattern list, is to limit the number of times the script will be called. Without this -pattern list, the script might be called thousands of times, depending on the number of cgroups available in the system. - -The above pattern list is matched against the path of the cgroup. For matched cgroups, Netdata calls the -script [cgroup-name.sh](https://raw.githubusercontent.com/netdata/netdata/master/collectors/cgroups.plugin/cgroup-name.sh) -to get its name. This script queries `docker`, `kubectl`, `podman`, or applies heuristics to find give a name for the -cgroup. - -#### Note on Podman container names - -Podman's security model is a lot more restrictive than Docker's, so Netdata will not be able to detect container names -out of the box unless they were started by the same user as Netdata itself. - -If Podman is used in "rootful" mode, it's also possible to use `podman system service` to grant Netdata access to -container names. To do this, ensure `podman system service` is running and Netdata has access -to `/run/podman/podman.sock` (the default permissions as specified by upstream are `0600`, with owner `root`, so you -will have to adjust the configuration). - -[Docker Socket Proxy (HAProxy)](https://github.com/Tecnativa/docker-socket-proxy) or [CetusGuard](https://github.com/hectorm/cetusguard) -can also be used to give Netdata restricted access to the socket. Note that `PODMAN_HOST` in Netdata's environment should -be set to the proxy's URL in this case. - -### Charts with zero metrics - -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. For example: - -```text -[plugin:cgroups] - enable memory (used mem including cache) = yes -``` - -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. - -### Alerts - -CPU and memory limits are watched and used to rise alerts. Memory usage for every cgroup is checked against `ram` -and `ram+swap` limits. CPU usage for every cgroup is checked against `cpuset.cpus` and `cpu.cfs_period_us` + `cpu.cfs_quota_us` pair assigned for the cgroup. Configuration for the alerts is available in `health.d/cgroups.conf` -file. - -## Monitoring systemd services - -Netdata monitors **systemd services**.

The program will show only resources for -cgroup `/`, but all services will show nothing. - -To enable cgroup accounting, execute this: - -```sh -sed -e 's|^#Default\(.*\)Accounting=.*$|Default\1Accounting=yes|g' /etc/systemd/system.conf >/tmp/system.conf -``` - -To see the changes it made, run this: - -```sh -# diff /etc/systemd/system.conf /tmp/system.conf -40,44c40,44 -< #DefaultCPUAccounting=no -< #DefaultIOAccounting=no -< #DefaultBlockIOAccounting=no -< #DefaultMemoryAccounting=no -< #DefaultTasksAccounting=yes ---- -> DefaultCPUAccounting=yes -> DefaultIOAccounting=yes -> DefaultBlockIOAccounting=yes -> DefaultMemoryAccounting=yes -> DefaultTasksAccounting=yes -``` - -If you are happy with the changes, run: - -```sh -# copy the file to the right location -sudo cp /tmp/system.conf /etc/systemd/system.conf - -# restart systemd to take it into account -sudo systemctl daemon-reexec -``` - -(`systemctl daemon-reload` does not reload the configuration of the server - so you have to -execute `systemctl daemon-reexec`). - -Now, when you run `systemd-cgtop`, services will start reporting usage (if it does not, restart any service to wake it up). Refresh your Netdata dashboard, and you will have the charts too. - -In case memory accounting is missing, you will need to enable it at your kernel, by appending the following kernel boot -options and rebooting: - -```sh -cgroup_enable=memory swapaccount=1 -``` - -You can add the above, directly at the `linux` line in your `/boot/grub/grub.cfg` or appending them to -the `GRUB_CMDLINE_LINUX` in `/etc/default/grub` (in which case you will have to run `update-grub` before rebooting). On -DigitalOcean debian images you may have to set it at `/etc/default/grub.d/50-cloudimg-settings.cfg`. - -Which systemd services are monitored by Netdata is determined by the following pattern list: - -```text -[plugin:cgroups] - cgroups to match as systemd services = !/system.slice/*/*.service /system.slice/*.service -``` - -- - - - -## Monitoring ephemeral containers - -Netdata monitors containers automatically when it is installed at the host, or when it is installed in a container that -has access to the `/proc` and `/sys` filesystems of the host. - -Network interfaces and cgroups (containers) are self-cleaned. When a network interface or container stops, Netdata might log -a few errors in error.log complaining about files it cannot find, but immediately: - -1. It will detect this is a removed container or network interface -2. It will freeze/pause all alerts for them -3. It will mark their charts as obsolete -4. Obsolete charts are not be offered on new dashboard sessions (so hit F5 and the charts are gone) -5. Existing dashboard sessions will continue to see them, but of course they will not refresh -6. Obsolete charts will be removed from memory, 1 hour after the last user viewed them (configurable - with `[global].cleanup obsolete charts after seconds = 3600` (at `netdata.conf`). -7.
