Monitoring Settings in Elasticsearch

Controls which indices Monitoring collects data from. Defaults to all indices. Specify the index names as a comma-separated list, for example test1,test2,test3. Names can include wildcards, for example test*. You can explicitly include or exclude indices by prepending + to include the index, or - to exclude the index. For example, to include all indices that start with test except test3, you could specify +test*,-test3.

You can update this setting through the Cluster Update Settings API.

Sets the retention duration beyond which the indices created by a Monitoring exporter will be automatically deleted. Defaults to 7d (7 days).

This setting has a minimum value of 1d (1 day) to ensure that something is being monitored, and it cannot be disabled.

Host supports multiple formats, both as an array or as a single value. Supported formats include hostname, hostname:port, http://hostname http://hostname:port, https://hostname, and https://hostname:port. Hosts cannot be assumed. The default scheme is always http and the default port is always 9200 if not supplied as part of the host string.

xpack.monitoring.exporters:
  example1:
    type: http
    host: "10.1.2.3"
  example2:
    type: http
    host: ["http://10.1.2.4"]
  example3:
    type: http
    host: ["10.1.2.5", "10.1.2.6"]
  example4:
    type: http
    host: ["https://10.1.2.3:9200"]

Optional headers that are added to every request, which can assist with routing requests through proxies.

xpack.monitoring.exporters.my_remote:
  headers:
    X-My-Array: [abc, def, xyz]
    X-My-Header: abc123

Array-based headers are sent n times where n is the size of the array. Content-Type and Content-Length cannot be set. Any headers created by the Monitoring agent will override anything defined here.
