Enable/Disable Event Data

Sysdig Monitor supports event integrations with certain applications by default. The Sysdig agent will automatically discover these services and begin collecting event data from them.

The following applications are currently supported:

  • Docker

  • Kubernetes

Other methods of ingesting custom events into Sysdig Monitor are touched upon in Custom Events.

By default, only a limited set of events is collected for a supported application, and are listed in the agent’s default settings configuration file (/opt/draios/etc/dragent.default.yaml).

To enable collecting other supported events, add an events entry to dragent.yaml.

You can also change log entry in dragent.yaml to filter events by severity.

Learn more about it in the following sections.

Supported Application Events

Events marked with * are enabled by default; see the dragent.default.yaml file.

Enable/Disable Events Collection with events Parameter

To customize the default events collected for a specific application (by either enabling or disabling events), add an events entry to dragent.yaml as described in the examples below.

An entry in a section in dragent.yaml overrides the entire section in the default configuration.

For example, the Pulling entry below will permit only kubernetes pod Pulling events to be collected and all other kubernetes pod events settings in dragent.default.yaml will be ignored.

However, other kubernetes sections - node and replicationController - remain intact and will be used as specified in dragent.default.yaml.

Example 1: Collect Only Certain Events

Collect only ‘Pulling’ events from Kubernetes for pods:

       - Pulling

Example 2: Disable All Events in a Section

To disable all events in a section, set the event section to none:

  kubernetes: none
  docker: none

Example 3: Combine Methods

These methods can be combined. For example, disable all kubernetes node and docker image events and limit docker container events to [attach, commit, copy] (components events in other sections will be collected as specified by default):

    node: none
    image: none
      - attach
      - commit
      - copy

Note: Format Sequences as List or Single Line

In addition to bulleted lists, sequences can also be specified in a bracketed single line, eg.:

    pod: [Pulling, Pulled, Failed]

So, the following two settings are equivalent, permitting only Pulling, Pulled, Failed events for pods to be emitted:

    pod: [Pulling, Pulled, Failed]

      - Pulling
      - Pulled
      - Failed

Change Event Collection by Severity with log Parameter

Events are limited globally at the agent level based on severity, using the log settings in dragent.yaml.

The default setting for the events severity filter is information (only warning and higher severity events are transmitted).

Valid severity levels are: none, emergency, alert, critical, error, warning, notice, information, debug.

Example 1: Block Low-Severity Messages

Block all low-severity messages (notice, information, debug):

  event_priority: warning

Example 2: Block All Event Collection

Block all event collection:

  event_priority: none

For other uses of the log settings see Optional: Change the Agent Log Level.
