Configuring Monitoringedit

Advanced monitoring settings enable you to control how frequently data is collected, configure timeouts, and set the retention period for locally-stored monitoring indices. You can also adjust how monitoring data is displayed. For more information, see Monitoring Settings.

Configuring Monitoring’s Indicesedit

Index templates are used to configure the indices that store the monitoring data collected from a cluster.

You can retrieve the templates through the _template API:

GET /_template/.monitoring-*

By default, the template configures one shard and one replica for the monitoring indices. To override the default settings, add your own template:

  1. Set the template pattern to .monitoring-*.
  2. Set the template order to 1. This ensures your template is applied after the default template, which has an order of 0.
  3. Specify the number_of_shards and/or number_of_replicas in the settings section.

For example, the following template increases the number of shards to five and the number of replicas to two.

PUT /_template/custom_monitoring
    "template": ".monitoring-*",
    "order": 1,
    "settings": {
        "number_of_shards": 5,
        "number_of_replicas": 2

Only set the number_of_shards and number_of_replicas in the settings section. Overriding other monitoring template settings could cause your monitoring dashboards to stop working correctly.
