Grafana Alloy is the new name for our distribution of the OTel collector. Grafana Agent has been deprecated and is in Long-Term Support (LTS) through October 31, 2025. Grafana Agent will reach an End-of-Life (EOL) on November 1, 2025. Read more about why we recommend migrating to Grafana Alloy.

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


Currently, an Agent can only collect metrics from a single ElasticSearch server. However, the exporter can collect the metrics from all nodes through that server configured.

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.


prometheus.exporter.elasticsearch "LABEL" {


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

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

basic_authbasic_authConfigure basic_auth for authenticating to the

basic_auth block

password_filestringFile containing the basic auth
passwordsecretBasic auth
usernamestringBasic auth

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.

targetslist(map(string))The targets that can be used to collect exporter metrics.

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.


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

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 {

    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.

Compatible components

prometheus.exporter.elasticsearch has exports that can be consumed by the following components:


Connecting some components may not be sensible or components may require further configuration to make the connection work correctly. Refer to the linked documentation for more details.
