prometheus.exporter.elasticsearch

The prometheus.exporter.elasticsearch component embeds elasticsearch_exporter for the collection of metrics from ElasticSearch servers.

We strongly recommend that you configure a separate user for the Agent, and give it only the strictly mandatory security privileges necessary for monitoring your node, as per the official documentation.

Usage

river Copy

prometheus.exporter.elasticsearch "LABEL" {
    address = "ELASTICSEARCH_ADDRESS"
}

Arguments

You can use the following arguments to configure the exporter’s behavior. Omitted fields take their default values.

Blocks

The following blocks are supported inside the definition of prometheus.exporter.elasticsearch:

basic_auth block

password and password_file are mutually exclusive, and only one can be provided inside a basic_auth block.

Exported fields

The following fields are exported and can be referenced by other components.

For example, the targets can either be passed to a discovery.relabel component to rewrite the targets’ label sets or to a prometheus.scrape component that collects the exposed metrics.

The exported targets use the configured in-memory traffic address specified by the run command.

Component health

prometheus.exporter.elasticsearch is only reported as unhealthy if given an invalid configuration. In those cases, exported fields retain their last healthy values.

Debug information

prometheus.exporter.elasticsearch does not expose any component-specific debug information.

Debug metrics

prometheus.exporter.elasticsearch does not expose any component-specific debug metrics.

Example

This example uses a prometheus.scrape component to collect metrics from prometheus.exporter.elasticsearch:

river Copy

prometheus.exporter.elasticsearch "example" {
  address = "http://localhost:9200"
  basic_auth {
    username = USERNAME
    password = PASSWORD
  }
}

// Configure a prometheus.scrape component to collect Elasticsearch metrics.
prometheus.scrape "demo" {
  targets    = prometheus.exporter.elasticsearch.example.targets
  forward_to = [prometheus.remote_write.demo.receiver]
}

prometheus.remote_write "demo" {
  endpoint {
    url = PROMETHEUS_REMOTE_WRITE_URL

    basic_auth {
      username = USERNAME
      password = PASSWORD
    }
  }
}

Replace the following:

• PROMETHEUS_REMOTE_WRITE_URL: The URL of the Prometheus remote_write-compatible server to send metrics to.
• USERNAME: The username to use for authentication to the remote_write API.
• PASSWORD: The password to use for authentication to the remote_write API.
