The following pipeline depicts a high-level overview of the different stages that collected logs propagate through for this to be achieved: - - - -The [Fluent Bit](https://github.com/fluent/fluent-bit) project has been used as the logs collection and exporting / streaming engine, due to its stability and the variety of [collection (input) plugins](https://docs.fluentbit.io/manual/pipeline/inputs) that it offers. Each collected log record passes through the Fluent Bit engine first, before it gets buffered, parsed, compressed and (optionally) stored locally by the logs management engine. It can also be streamed to another Netdata or Fluent Bit instance (using Fluent Bit's [Forward](https://docs.fluentbit.io/manual/pipeline/outputs/forward) protocol), or exported using any other [Fluent Bit output](https://docs.fluentbit.io/manual/pipeline/outputs). - -A bespoke circular buffering implementation has been used to maximize performance and optimize memory utilization. More technical details about how it works can be found [here](https://github.com/netdata/netdata/pull/13291#buffering). - -To configure Netdata's logs management engine properly, please make sure you are aware of the following points first: - -* One collection cycle (at max) occurs per `update every` interval (in seconds - minimum 1 sec) and any log records collected in a collection cycle are grouped together (for compression and performance purposes). As a result of this, a longer `update every` interval will reduce memory and disk space requirements. -* When collected logs contain parsable timestamps, these will be used to display metrics from parsed logs at the correct time in each chart, even if collection of said logs takes place *much* later than the time they were produced. How much later? Up to a configurable value of `update timeout` seconds. This mechanism ensures correct parsing and querying of delayed logs that contain parsable timestamps (such as streamed inputs or buffered logs sources that write logs in batches), but the respective charts may lag behind some seconds up to that timeout. If no parsable timestamp is found, the collection timestamp will be used instead (or the collector can be forced to always use the collection timestamp by setting `use log timestamp = no`). - -<a name="collector-types"/> - -### Types of available log collectors - -</a> - -The following log collectors are supported at the moment. The table will be updated as more collectors are added: -| Collector | Log type | Description | -| ------------ | ------------ | ------------ | -| kernel logs (kmsg) | `flb_kmsg` | Collection of new kernel ring buffer logs.| -| systemd | `flb_systemd` | Collection of journald logs.| -| docker events | `flb_docker_events` | Collection of docker events logs, similar to executing the `docker events` command.| -| tail | `flb_tail` | Collection of new logs from files by "tailing" them, similar to `tail -f`.| -| web log | `flb_web_log` | Collection of Apache or Nginx access logs.| -| syslog socket | `flb_syslog` | Collection of RFC-3164 syslog logs by creating listening sockets.| -| serial | `flb_serial` | Collection of logs from a serial interface.| -| mqtt | `flb_mqtt` | Collection of MQTT messages over a TCP connection.| - -<a name="getting-started"/> - -## Getting Started - -</a> - -Since version `XXXXX`, Netdata is distributed with logs management functionality as an external plugin, but it is disabled by default and must be explicitly enabled using `./edit-config netdata.conf` and changing the respective configuration option: - -``` -[plugins] - logs-management = yes -``` - -There are some pre-configured log sources that Netdata will attempt to automatically discover and monitor that can be edited using `./edit-config logsmanagement.d/default.conf` in Netdata's configuration directory. More sources can be configured for monitoring by adding them in `logsmanagement.d/default.conf` or in other `.conf` files in the `logsmanagement.d` directory. - -There are also some example configurations that can be listed using `./edit-config --list`. - -To get familiar with the Logs Management functionality, the user is advised to read at least the [Summary](#summary) and the [General Configuration](#general-configuration) sections and also any [Collector-specific Configuration](#collector-configuration) subsections, according to each use case. - -For any issues, please refer to [Troubleshooting](#troubleshooting) or open a new support ticket on [Github](https://github.com/netdata/netdata/issues) or one of Netdata's support channels. - -<a name="package-requirements"/> - -## Package Requirements - -</a> - -Netdata logs management introduces minimal additional package dependencies and those are actually [Fluent Bit dependencies](https://docs.fluentbit.io/manual/installation/requirements). The only extra build-time dependencies are: -- `flex` -- `bison` -- `musl-fts-dev` ([Alpine Linux](https://www.alpinelinux.org/about) only) - -However, there may be some exceptions to this rule as more collectors are added to the logs management engine, so if a specific collector is disabled due to missing dependencies, please refer to this section or check [Troubleshooting](#troubleshooting). - -<a name="general-configuration"/> - -## General Configuration - -</a> - -There are some fundamental configuration options that are common to all log collector types. These options can be set globally in `logsmanagement.d.conf` or they can be customized per log source: - -| Configuration Option | Default | Description | -| :------------: | :------------: | ------------ | -| `update every` | Equivalent value in `logsmanagement.d.conf` (or in `netdata.conf` under `[plugin:logs-management]`, if higher). | How often metrics in charts will be updated every (in seconds). -| `update timeout` | Equivalent value in `[logs management]` section of `netdata.conf` (or Netdata global value, if higher). | Maximum timeout charts may be delayed by while waiting for new logs. -| `use log timestamp` | Equivalent value in `logsmanagement.d.conf` (`auto` by default). | If set to `auto`, log timestamps (when available) will be used for precise metrics aggregation. Otherwise (if set to `no`), collection timestamps will be used instead (which may result in lagged metrics under heavy system load, but it will reduce CPU usage). -| `log type` | `flb_tail` | Type of this log collector, see [relevant table](#collector-types) for a complete list of supported collectors. -| `circular buffer max size` | Equivalent value in `logsmanagement.d.conf`. | Maximum RAM that can be used to buffer collected logs until they are saved to the disk database. -| `circular buffer drop logs if full` | Equivalent value in `logsmanagement.d.conf` (`no` by default). | If there are new logs pending to be collected and the circular buffer is full, enabling this setting will allow old buffered logs to be dropped in favor of new ones. If disabled, collection of new logs will be blocked until there is free space again in the buffer (no logs will be lost in this case, but logs will not be ingested in real-time). -| `compression acceleration` | Equivalent value in `logsmanagement.d.conf` (`1` by default). | Fine-tunes tradeoff between log compression speed and compression ratio, see [here](https://github.com/lz4/lz4/blob/90d68e37093d815e7ea06b0ee3c168cccffc84b8/lib/lz4.h#L195) for more details. -| `db mode` | Equivalent value in `logsmanagement.d.conf` (`none` by default). | Mode of logs management database per collector. If set to `none`, logs will be collected, buffered, parsed and then discarded. If set to `full`, buffered logs will be saved to the logs management database instead of being discarded. When mode is `none`, logs management queries cannot be executed. -| `buffer flush to DB` | Equivalent value in `logsmanagement.d.conf` (`6` by default). | Interval in seconds at which logs will be transferred from RAM buffers to the database. -| `disk space limit` | Equivalent value in `logsmanagement.d.conf` (`500 MiB` by default). | Maximum disk space that all compressed logs in database can occupy (per log source). Once exceeded, oldest BLOB of logs will be truncated for new logs to be written over. Each log source database can contain a maximum of 10 BLOBs at any point, so each truncation equates to a deletion of about 10% of the oldest logs. The number of BLOBS will be configurable in a future release. -| `collected logs total chart enable` | Equivalent value in `logsmanagement.d.conf` (`no` by default). | Chart that shows the number of log records collected for this log source, since the last Netdata agent restart. Useful for debugging purposes. -| `collected logs rate chart enable` | Equivalent value in `logsmanagement.d.conf` (`yes` by default). | Chart that shows the rate that log records are collected at for this log source. -| `submit logs to system journal = no` | Equivalent value in `logsmanagement.d.conf` (`no` by default). Available only for `flb_tail`, `flb_web_log`, `flb_serial`, `flb_docker_events` and `flb_mqtt`. | If enabled, it will submit the collected logs to the system journal. - -There is also one setting that cannot be set per log source, but can only be defined in `logsmanagement.d.conf`: - -| Configuration Option | Default | Description | -| :------------: | :------------: | ------------ | -| `db dir` | `/var/cache/netdata/logs_management_db` | Logs management database path, will be created if it does not exist.| - - - -> **Note** -> `log path` must be defined per log source for any collector type, except for `kmsg` and the collectors that listen to network sockets. Some default examples use `log path = auto`. In those cases, an autodetection of the path will be attempted by searching through common paths where each log source is typically expected to be found. - -<a name="collector-configuration"/> - -## Collector-specific Configuration - -</a> - -<a name="collector-configuration-kmsg"/> - -### Kernel logs (kmsg) - -</a> - -This collector will collect logs from the kernel message log buffer. See also documentation of [Fluent Bit kmsg input plugin](https://docs.fluentbit.io/manual/pipeline/inputs/kernel-logs). - -> **Warning** -> If `use log timestamp` is set to `auto` and the system has been in suspend and resumed since the last boot, timestamps of new `kmsg` logs will be incorrect and log collection will not work. This is a know limitation when reading the kernel log buffer records and it is recommended to use `use log timestamp = no` in this case. - -> **Note** -> `/dev/kmsg` normally returns all the logs in the kernel log buffer every time it is read. To avoid duplicate logs, the collector will discard any previous logs the first time `/dev/kmsg` is read after an agent restart and it will collect only new kernel logs. - -| Configuration Option | Description | -| :------------: | ------------ | -| `prio level` | Drop kernel logs with priority higher than `prio level`. Default value is 8, so no logs will be dropped. -| `severity chart` | Enable chart showing Syslog Severity values of collected logs. Severity values are in the range of 0 to 7 inclusive.| -| `subsystem chart` | Enable chart showing which subsystems generated the logs.| -| `device chart` | Enable chart showing which devices generated the logs.| - -<a name="collector-configuration-systemd"/> - -### Systemd - -</a> - -This collector will collect logs from the journald daemon. See also documentation of [Fluent Bit systemd input plugin](https://docs.fluentbit.io/manual/pipeline/inputs/systemd). - -| Configuration Option | Description | -| :------------: | ------------ | -| `log path` | Path to the systemd journal directory. If set to `auto`, the default path will be used to read local-only logs. | -| `priority value chart` | Enable chart showing Syslog Priority values (PRIVAL) of collected logs. The Priority value ranges from 0 to 191 and represents both the Facility and Severity. It is calculated by first multiplying the Facility number by 8 and then adding the numerical value of the Severity. Please see the [rfc5424: Syslog Protocol](https://www.rfc-editor.org/rfc/rfc5424#section-6.2.1) document for more information.| -| `severity chart` | Enable chart showing Syslog Severity values of collected logs. Severity values are in the range of 0 to 7 inclusive.| -| `facility chart` | Enable chart showing Syslog Facility values of collected logs. Facility values show which subsystem generated the log and are in the range of 0 to 23 inclusive.| - -<a name="collector-configuration-docker-events"/> - -### Docker events - -</a> - -This collector will use the Docker API to collect Docker events logs. See also documentation of [Fluent Bit docker events input plugin](https://docs.fluentbit.io/manual/pipeline/inputs/docker-events). - -| Configuration Option | Description | -| :------------: | ------------ | -| `log path` | Docker socket UNIX path. If set to `auto`, the default path (`/var/run/docker.sock`) will be used. | -| `event type chart` | Enable chart showing the Docker object type of the collected logs. | -| `event action chart` | Enable chart showing the Docker object action of the collected logs. | - -<a name="collector-configuration-tail"/> - -### Tail - -</a> - -This collector will collect any type of logs from a log file, similar to executing the `tail -f` command. See also documentation of [Fluent Bit tail plugin](https://docs.fluentbit.io/manual/pipeline/inputs/tail). - -| Configuration Option | Description | -| :------------: | ------------ | -| `log path` | The path to the log file to be monitored. | -| `use inotify` | Select between inotify and file stat watchers (providing `libfluent-bit.so` has been built with inotify support). It defaults to `yes`. Set to `no` if abnormally high CPU usage is observed or if the log source is expected to consistently produce tens of thousands of (unbuffered) logs per second. | - -<a name="collector-configuration-web-log"/> - -### Web log - -</a> - -This collector will collect [Apache](https://httpd.apache.org/) and [Nginx](https://nginx.org/) access logs. - -| Configuration Option | Description | -| :------------: | ------------ | -| `log path` | The path to the web server's `access.log`. If set to `auto`, the collector will attempt to auto-discover it, provided the name of the configuration section is either `Apache access.log` or `Nginx access.log`. | -| `use inotify` | Select between inotify and file stat watchers (providing `libfluent-bit.so` has been built with inotify support). It defaults to `yes`. Set to `no` if abnormally high CPU usage is observed or if the log source is expected to consistently produce tens of thousands of (unbuffered) logs per second. | -| `log format` | The log format to be used for parsing. Unlike the [`GO weblog`]() module, only the `CSV` parser is supported and it can be configured [in the same way](/src/go/collectors/go.d.plugin/modules/weblog/README.md#known-fields) as in the `GO` module. If set to `auto`, the collector will attempt to auto-detect the log format using the same logic explained [here](/src/go/collectors/go.d.plugin/modules/weblog/README.md#log-parser-auto-detection). | -| `verify parsed logs` | If set to `yes`, the parser will attempt to verify that the parsed fields are valid, before extracting metrics from them. If they are invalid (for example, the response code is less than `100`), the `invalid` dimension will be incremented instead. Setting this to `no` will result in a slight performance gain. | -| `vhosts chart` | Enable chart showing names of the virtual hosts extracted from the collected logs. | -| `ports chart` | Enable chart showing port numbers extracted from the collected logs. | -| `IP versions chart` | Enable chart showing IP versions (`v4` or `v6`) extracted from the collected logs. | -| `unique client IPs - current poll chart` | Enable chart showing unique client IPs in each collection interval. | -| `unique client IPs - all-time chart` | Enable chart showing unique client IPs since agent startup. It is recommended to set this to `no` as it can have a negative impact on long-term performance. | -| `http request methods chart` | Enable chart showing HTTP request methods extracted from the collected logs. | -| `http protocol versions chart` | Enable chart showing HTTP protocol versions exctracted from the collected logs. | -| `bandwidth chart` | Enable chart showing request and response bandwidth extracted from the collected logs. | -| `timings chart` | Enable chart showing request processing time stats extracted from the collected logs. | -| `response code families chart` | Enable chart showing response code families (`1xx`, `2xx` etc.) extracted from the collected logs. | -| `response codes chart` | Enable chart showing response codes extracted from the collected logs. | -| `response code types chart` | Enable chart showing response code types (`success`, `redirect` etc.) extracted from the collected logs. | -| `SSL protocols chart` | Enable chart showing SSL protocols (`TLSV1`, `TLSV1.1` etc.) exctracted from the collected logs. | -| `SSL chipher suites chart` | Enable chart showing SSL chipher suites exctracted from the collected logs. | - -<a name="collector-configuration-syslog"/> - -### Syslog socket - -</a> - -This collector will collect logs through a Unix socket server (UDP or TCP) or over the network using TCP or UDP. See also documentation of [Fluent Bit syslog input plugin](https://docs.fluentbit.io/manual/pipeline/inputs/syslog). - -| Configuration Option | Description | -| :------------: | ------------ | -| `mode` | Type of socket to be created to listen for incoming syslog messages. Supported modes are: `unix_tcp`, `unix_udp`, `tcp` and `udp`.| -| `log path` | If `mode == unix_tcp` or `mode == unix_udp`, Netdata will create a UNIX socket on this path to listen for syslog messages. Otherwise, this option is not used.| -| `unix_perm` | If `mode == unix_tcp` or `mode == unix_udp`, this sets the permissions of the generated UNIX socket. Otherwise, this option is not used.| -| `listen` | If `mode == tcp` or `mode == udp`, this sets the network interface to bind.| -| `port` | If `mode == tcp` or `mode == udp`, this specifies the port to listen for incoming connections.| -| `log format` | This is a Ruby Regular Expression to define the expected syslog format. Fluent Bit provides some [pre-configured syslog parsers](https://github.com/fluent/fluent-bit/blob/master/conf/parsers.conf#L65). | -|`priority value chart` | Please see the respective [systemd](#collector-configuration-systemd) configuration.| -| `severity chart` | Please see the respective [systemd](#collector-configuration-systemd) configuration.| -| `facility chart` | Please see the respective [systemd](#collector-configuration-systemd) configuration.| - - For parsing and metrics extraction to work properly, please ensure fields `<PRIVAL>`, `<SYSLOG_TIMESTAMP>`, `<HOSTNAME>`, `<SYSLOG_IDENTIFIER>`, `<PID>` and `<MESSAGE>` are defined in `log format`. For example, to parse incoming `syslog-rfc3164` logs, the following regular expression can be used: - -``` -/^\<(?<PRIVAL>[0-9]+)\>(?<SYSLOG_TIMESTAMP>[^ ]* {1,2}[^ ]* [^ ]* )(?<HOSTNAME>[^ ]*) (?<SYSLOG_IDENTIFIER>[a-zA-Z0-9_\/\.\-]*)(?:\[(?<PID>[0-9]+)\])?(?:[^\:]*\:)? *(?<MESSAGE>.*)$/ -``` - -<a name="collector-configuration-serial"/> - -### Serial - -</a> - -This collector will collect logs through a serial interface. See also documentation of [Fluent Bit serial interface input plugin](https://docs.fluentbit.io/manual/pipeline/inputs/serial-interface). - -| Configuration Option | Description | -| :------------: | ------------ | -| `log path` | Absolute path to the device entry, e.g: `/dev/ttyS0`.| -| `bitrate` | The bitrate for the communication, e.g: 9600, 38400, 115200, etc..| -| `min bytes` | The minimum bytes the serial interface will wait to receive before it begines to process the log message.| -| `separator` | An optional separator string to determine the end of a log message.| -| `format` | Specify the format of the incoming data stream. The only option available is 'json'. Note that Format and Separator cannot be used at the same time.| - -<a name="collector-configuration-mqtt"/> - -### MQTT - -</a> - -This collector will collect MQTT data over a TCP connection, by spawning an MQTT server through Fluent Bit. See also documentation of [Fluent Bit MQTT input plugin](https://docs.fluentbit.io/manual/pipeline/inputs/mqtt). - -| Configuration Option | Description | -| :------------: | ------------ | -| `listen` | Specifies the network interface to bind.| -| `port` | Specifies the port to listen for incoming connections.| -| `topic chart` | Enable chart showing MQTT topic of incoming messages.| - -<a name="custom-charts"/> - -## Custom Charts - -</a> - -In addition to the predefined charts, each log source supports the option to extract -user-defined metrics, by matching log records to [POSIX Extended Regular Expressions](https://en.wikibooks.org/wiki/Regular_Expressions/POSIX-Extended_Regular_Expressions). -This can be very useful particularly for `FLB_TAIL` type log sources, where -there is no parsing at all by default. - -To create a custom chart, the following key-value configuration options must be -added to the respective log source configuration section: - -``` - custom 1 chart = identifier - custom 1 regex name = kernel - custom 1 regex = .*\bkernel\b.* - custom 1 ignore case = no -``` - -where the value denoted by: -- `custom x chart` is the title of the chart. -- `custom x regex name` is an optional name for the dimension of this particular metric (if absent, the regex will be used as the dimension name instead). -- `custom x regex` is the POSIX Extended Regular Expression to be used to match log records. -- `custom x ignore case` is equivalent to setting `REG_ICASE` when using POSIX Extended Regular Expressions for case insensitive searches. It is optional and defaults to `yes`. - -`x` must start from number 1 and monotonically increase by 1 every time a new regular expression is configured. -If the titles of two or more charts of a certain log source are the same, the dimensions will be grouped together -in the same chart, rather than a new chart being created. - -Example of configuration for a generic log source collection with custom regex-based parsers: - -``` -[Auth.log] - ## Example: Log collector that will tail auth.log file and count - ## occurences of certain `sudo` commands, using POSIX regular expressions. - - ## Required settings - enabled = no - log type = flb_tail - - ## Optional settings, common to all log source. - ## Uncomment to override global equivalents in netdata.conf. - # update every = 1 - # update timeout = 10 - # use log timestamp = auto - # circular buffer max size MiB = 64 - # circular buffer drop logs if full = no - # compression acceleration = 1 - # db mode = none - # circular buffer flush to db = 6 - # disk space limit MiB = 500 - - ## This section supports auto-detection of log file path if section name - ## is left unchanged, otherwise it can be set manually, e.g.: - ## log path = /var/log/auth.log - ## See README for more information on 'log path = auto' option - log path = auto - - ## Use inotify instead of file stat watcher.

Fluent Bit's [Forward protocol](https://docs.fluentbit.io/manual/pipeline/outputs/forward). - -For option 1, please refer to the [syslog collector](#collector-configuration-syslog) section. This section will be focused on using option 2. - -A Netdata agent can be used as a logs aggregation parent to listen to `Forward` messages, using either Unix or network sockets. This option is separate to [Netdata's metrics streaming](/docs/observability-centralization-points/README.md) and can be used independently of whether that's enabled or not (and it uses a different listening socket too). - -This setting can be enabled under the `[forward input]` section in `logsmanagement.d.conf`: - -``` -[forward input] - enable = no - unix path = - unix perm = 0644 - listen = 0.0.0.0 - port = 24224 -``` - -The default settings will listen for incoming `Forward` messages on TCP port 24224. If `unix path` is set to a valid path, `listen` and `port` will be ignored and a unix socket will be created under that path. Make sure that `unix perm` has the correct permissions set for that unix socket. Please also see Fluent Bit's [Forward input plugin documentation](https://docs.fluentbit.io/manual/pipeline/inputs/forward). - -The Netdata agent will now listen for incoming `Forward` messages, but by default it won't process or store them. To do that, there must exist at least one log collection, to define how the incoming logs will be processed and stored. This is similar to configuring a local log source, with the difference that `log source = forward` must be set and also a `stream guid` must be defined, matching that of the children log sources. - -The rest of this section contains some examples on how to configure log collections of different types, using a Netdata parent and Fluent Bit children instances (see also `./edit-config logsmanagement.d/example_forward.conf`). Please use the recommended settings on children instances for parsing on parents to work correctly. Also, note that `Forward` output on children supports optional `gzip` compression, by using the `-p Compress=gzip` configuration parameter, as demonstrated in some of the examples. - -<a name="streaming-systemd"/> - -### Example: Systemd log streaming - -</a> - -Example configuration of an `flb_docker_events` type parent log collection: -``` -[Forward systemd] - - ## Required settings - enabled = yes - log type = flb_systemd - - ## Optional settings, common to all log source. - ## Uncomment to override global equivalents in netdata.conf. - # update every = 1 - # update timeout = 10 - # use log timestamp = auto - # circular buffer max size MiB = 64 - # circular buffer drop logs if full = no - # compression acceleration = 1 - # db mode = none - # circular buffer flush to db = 6 - # disk space limit MiB = 500 - - ## Streaming input settings. - log source = forward - stream guid = 6ce266f5-2704-444d-a301-2423b9d30735 - - ## Other settings specific to this log source type - priority value chart = yes - severity chart = yes - facility chart = yes -``` - -Any children can be configured as follows: -``` -fluent-bit -i systemd -p Read_From_Tail=on -p Strip_Underscores=on -o forward -p Compress=gzip -F record_modifier -p 'Record="stream guid" 6ce266f5-2704-444d-a301-2423b9d30735' -m '*' -``` - -<a name="streaming-kmsg"/> - -### Example: Kernel log streaming - -</a> - -Example configuration of an `flb_kmsg` type parent log collection: -``` -[Forward kmsg] - - ## Required settings - enabled = yes - log type = flb_kmsg - - ## Optional settings, common to all log source. - ## Uncomment to override global equivalents in netdata.conf. - # update every = 1 - # update timeout = 10 - use log timestamp = no - # circular buffer max size MiB = 64 - # circular buffer drop logs if full = no - # compression acceleration = 1 - # db mode = none - # circular buffer flush to db = 6 - # disk space limit MiB = 500 - - ## Streaming input settings. - log source = forward - stream guid = 6ce266f5-2704-444d-a301-2423b9d30736 - - ## Other settings specific to this log source type - severity chart = yes - subsystem chart = yes - device chart = yes -``` -Any children can be configured as follows: -``` -fluent-bit -i kmsg -o forward -p Compress=gzip -F record_modifier -p 'Record="stream guid" 6ce266f5-2704-444d-a301-2423b9d30736' -m '*' -``` - -> **Note** -> Fluent Bit's `kmsg` input plugin will collect all kernel logs since boot every time it's started up.
