Add APM user settings

Change how the APM Server runs by providing your own user settings. User settings are appended to the apm-server.yml configuration file for your instance and provide custom configuration options.

Tip

Some settings that could break your cluster if set incorrectly are blacklisted. Review the list of settings that are generally safe in cloud environments. For detailed information about APM settings, see the APM documentation.

To add user settings:

  1. Log into the Elasticsearch Service Console.
  2. On the Deployments page, select your deployment.

    Narrow your deployments by name, ID, or choose from several other filters. To customize your view, use a combination of filters, or change the format from a grid to a list.

  3. From your deployment menu, go to the Edit page.
  4. At the bottom of the APM instance, expand the User settings overrides caret.
  5. Update the user settings.
  6. Click Save changes.
Note

If a setting is not supported by Elasticsearch Service, you will get an error message when you try to save.

Supported APM settings

Elasticsearch Service supports the following APM settings.

For version 6.5 and later:

This stack version includes all of the settings from 6.4 and the following:

apm-server.max_event_size
Specifies the maximum allowed size of an event for processing by the server, in bytes. Defaults to 307200.
output.elasticsearch.pipelines
Adds an array for pipeline selector configurations that support conditionals, format string-based field access, and name mappings used to parse data using ingest node pipelines.
apm-server.register.ingest.pipeline.enabled
Loads the pipeline definitions to Elasticsearch when the APM Server starts up. Defaults to false.
apm-server.register.ingest.pipeline.overwrite
Overwrites the existing pipeline definitions in Elasticsearch. Defaults to true.
apm-server.rum.event_rate.lru_size
Defines the number of unique IP addresses that can be tracked in the LRU cache, which keeps a rate limit for each of the most recently seen IP addresses. Defaults to 1000.
apm-server.rum.event_rate.limit
Sets the rate limit per second for each IP address for events sent to the APM Server v2 RUM endpoint. Defaults to 300.
