{beatname_uc} supports autodiscover based on hints from the provider. The hints system looks for
|
||
|
hints in Kubernetes Pod annotations or Docker labels that have the prefix `co.elastic.logs`. As soon as
|
||
|
the container starts, {beatname_uc} will check if it contains any hints and launch the proper config for
|
||
|
it. Hints tell {beatname_uc} how to get logs for the given container. By default logs will be retrieved
|
||
|
from the container using the `docker` input. You can use hints to modify this behavior. This is the full
|
||
|
list of supported hints:
|
||
|
|
||
|
[float]
|
||
|
===== `co.elastic.logs/disable`
|
||
|
|
||
|
Filebeat gets logs from all containers by default, you can set this hint to `true` to ignore
|
||
|
the output of the container. Filebeat won't read or send logs from it.
|
||
|
|
||
|
[float]
|
||
|
===== `co.elastic.logs/multiline.*`
|
||
|
|
||
|
Multiline settings. See <<multiline-examples>> for a full list of all supported options.
|
||
|
|
||
|
[float]
|
||
|
===== `co.elastic.logs/include_lines`
|
||
|
|
||
|
A list of regular expressions to match the lines that you want {beatname_uc} to include.
|
||
|
See <<configuration-filebeat-options>> for more info.
|
||
|
|
||
|
[float]
|
||
|
===== `co.elastic.logs/exclude_lines`
|
||
|
|
||
|
A list of regular expressions to match the lines that you want {beatname_uc} to exclude.
|
||
|
See <<configuration-filebeat-options>> for more info.
|
||
|
|
||
|
[float]
|
||
|
===== `co.elastic.logs/module`
|
||
|
|
||
|
Instead of using raw `docker` input, specifies the module to use to parse logs from the container. See
|
||
|
<<filebeat-modules>> for the list of supported modules.
|
||
|
|
||
|
[float]
|
||
|
===== `co.elastic.logs/fileset`
|
||
|
|
||
|
When module is configured, map container logs to module filesets. You can either configure
|
||
|
a single fileset like this:
|
||
|
|
||
|
["source","yaml",subs="attributes"]
|
||
|
-------------------------------------------------------------------------------------
|
||
|
co.elastic.logs/fileset: access
|
||
|
-------------------------------------------------------------------------------------
|
||
|
|
||
|
Or configure a fileset per stream in the container (stdout and stderr):
|
||
|
|
||
|
["source","yaml",subs="attributes"]
|
||
|
-------------------------------------------------------------------------------------
|
||
|
co.elastic.logs/fileset.stdout: access
|
||
|
co.elastic.logs/fileset.stderr: error
|
||
|
-------------------------------------------------------------------------------------
|
||
|
|
||
|
[float]
|
||
|
===== `co.elastic.logs/raw`
|
||
|
When an entire input/module configuration needs to be completely set the `raw` hint can be used. You can provide a
|
||
|
stringified JSON of the input configuration. `raw` overrides every other hint and can be used to create bot a single or
|
||
|
a list of configurations.
|
||
|
|
||
|
["source","yaml",subs="attributes"]
|
||
|
-------------------------------------------------------------------------------------
|
||
|
co.elastic.logs/raw: "[{\"containers\":{\"ids\":[\"${data.container.id}\"]},\"multiline\":{\"negate\":\"true\",\"pattern\":\"^test\"},\"type\":\"docker\"}]"
|
||
|
-------------------------------------------------------------------------------------
|
||
|
|
||
|
[float]
|
||
|
===== `co.elastic.logs/processors`
|
||
|
|
||
|
Define a processor to be added to the {beatname_uc} input/module configuration. See <<filtering-and-enhancing-data>> for the list
|
||
|
of supported processors.
|
||
|
|
||
|
In order to provide ordering of the processor definition, numbers can be provided. If not, the hints builder will do
|
||
|
arbitrary ordering:
|
||
|
|
||
|
["source","yaml"]
|
||
|
-------------------------------------------------------------------------------------
|
||
|
co.elastic.logs/processors.1.dissect.tokenizer: "%{key1} %{key2}"
|
||
|
co.elastic.logs/processors.dissect.tokenizer: "%{key2} %{key1}"
|
||
|
-------------------------------------------------------------------------------------
|
||
|
|
||
|
In the above sample the processor definition tagged with `1` would be executed first.
|
||
|
|
||
|
[float]
|
||
|
==== Kubernetes
|
||
|
|
||
|
Kubernetes autodiscover provider supports hints in Pod annotations. To enable it just set `hints.enabled`:
|
||
|
|
||
|
["source","yaml",subs="attributes"]
|
||
|
-------------------------------------------------------------------------------------
|
||
|
filebeat.autodiscover:
|
||
|
providers:
|
||
|
- type: kubernetes
|
||
|
hints.enabled: true
|
||
|
-------------------------------------------------------------------------------------
|
||
|
|
||
|
You can annotate Kubernetes Pods with useful info to spin up {beatname_uc} inputs or modules:
|
||
|
|
||
|
["source","yaml",subs="attributes"]
|
||
|
-------------------------------------------------------------------------------------
|
||
|
annotations:
|
||
|
co.elastic.logs/multiline.pattern: '^\['
|
||
|
co.elastic.logs/multiline.negate: true
|
||
|
co.elastic.logs/multiline.match: after
|
||
|
-------------------------------------------------------------------------------------
|
||
|
|
||
|
|
||
|
[float]
|
||
|
===== Multiple containers
|
||
|
|
||
|
When a pod has multiple containers, the settings are shared unless you put the container name in the
|
||
|
hint. For example, these hints configure multiline settings for all containers in the pod, but set a
|
||
|
specific `exclude_lines` hint for the container called `sidecar`.
|
||
|
|
||
|
|
||
|
["source","yaml",subs="attributes"]
|
||
|
-------------------------------------------------------------------------------------
|
||
|
annotations:
|
||
|
co.elastic.logs/multiline.pattern: '^\['
|
||
|
co.elastic.logs/multiline.negate: true
|
||
|
co.elastic.logs/multiline.match: after
|
||
|
co.elastic.logs.sidecar/exclude_lines: '^DBG'
|
||
|
-------------------------------------------------------------------------------------
|
||
|
|
||
|
|
||
|
|
||
|
[float]
|
||
|
==== Docker
|
||
|
|
||
|
Docker autodiscover provider supports hints in labels. To enable it just set `hints.enabled`:
|
||
|
|
||
|
["source","yaml",subs="attributes"]
|
||
|
-------------------------------------------------------------------------------------
|
||
|
filebeat.autodiscover:
|
||
|
providers:
|
||
|
- type: docker
|
||
|
hints.enabled: true
|
||
|
-------------------------------------------------------------------------------------
|
||
|
|
||
|
You can label Docker containers with useful info to spin up {beatname_uc} inputs, for example:
|
||
|
|
||
|
["source","yaml",subs="attributes"]
|
||
|
-------------------------------------------------------------------------------------
|
||
|
co.elastic.logs/module: nginx
|
||
|
co.elastic.logs/fileset.stdout: access
|
||
|
co.elastic.logs/fileset.stderr: error
|
||
|
-------------------------------------------------------------------------------------
|
||
|
|
||
|
The above labels configure {beatname_uc} to use the Nginx module to harvest logs for this container.
|
||
|
Access logs will be retrieved from stdout stream, and error logs from stderr.
