This is a builtin exporter from Elasticsearch to Prometheus. It collects all relevant metrics and makes them available to Prometheus via the Elasticsearch REST API.
Currently, the available metrics are:
- Cluster status
- Nodes status:
- JVM
- Indices (global)
- Transport
- HTTP
- Scripts
- Process
- Operating System
- File System
- Circuit Breaker
- Indices status
- Cluster settings (selected disk allocation settings only)

Since Elasticsearch 7.0.0 :
./bin/elasticsearch-plugin install -b https://github.com/vvanholl/elasticsearch-prometheus-exporter/releases/download/7.3.2.0/prometheus-exporter-7.3.2.0.zip -
Since Elasticsearch 6.0.0 :
./bin/elasticsearch-plugin install -b https://github.com/vvanholl/elasticsearch-prometheus-exporter/releases/download/6.8.0.0/prometheus-exporter-6.8.0.0.zip -
On Elasticsearch 5.x.x :
./bin/elasticsearch-plugin install -b https://github.com/vvanholl/elasticsearch-prometheus-exporter/releases/download/5.6.16.0/elasticsearch-prometheus-exporter-5.6.16.0.zip -
On old 2.x.x versions :
./bin/plugin install https://github.com/vvanholl/elasticsearch-prometheus-exporter/releases/download/2.4.1.0/elasticsearch-prometheus-exporter-2.4.1.0.zip
Do not forget to restart the node after the installation!
Note that the plugin needs the following special permissions:
- java.lang.RuntimePermission accessClassInPackage.sun.misc
- java.lang.RuntimePermission accessDeclaredMembers
- java.lang.reflect.ReflectPermission suppressAccessChecks
If you have a lot of indices and think this data is irrelevant, you can disable in the main configuration file:
prometheus.indices: false
To disable exporting cluster settings use:
prometheus.cluster.settings: false
These settings can be also updated dynamically.

Since Elasticsearch 6.0.0:
./bin/elasticsearch-plugin remove prometheus-exporter -
On Elasticsearch 5.x.x:
./bin/elasticsearch-plugin remove prometheus-exporter -
On old 2.x.x versions:
./bin/plugin remove prometheus-exporter
Do not forget to restart the node after installation!
Metrics are directly available at:
http://<your-elasticsearch-host>:9200/_prometheus/metrics
As a sample result, you get:
# HELP es_process_mem_total_virtual_bytes Memory used by ES process
# TYPE es_process_mem_total_virtual_bytes gauge
es_process_mem_total_virtual_bytes{cluster="develop",node="develop01",} 3.626733568E9
# HELP es_indices_indexing_is_throttled_bool Is indexing throttling ?
# TYPE es_indices_indexing_is_throttled_bool gauge
es_indices_indexing_is_throttled_bool{cluster="develop",node="develop01",} 0.0
# HELP es_jvm_gc_collection_time_seconds Time spent for GC collections
# TYPE es_jvm_gc_collection_time_seconds counter

es_jvm_mem_nonheap_used_bytes{cluster="develop",node="develop01",} 5.5302736E7
...
On your Prometheus servers, configure a new job as usual.
For example, if you have a cluster of 3 nodes:
- job_name: elasticsearch
scrape_interval: 10s
metrics_path: "/_prometheus/metrics"
static_configs:
- targets:
- node1:9200
- node2:9200
- node3:9200Of course, you could use the service discovery service instead of a static config.
Just keep in mind that metrics_path must be /_prometheus/metrics, otherwise Prometheus will find no metric.
The Maven project site is available at GitHub.
Project contains integration tests implemented using rest layer framework.
Complete test suite is run using:
gradle clean check
To run individual test file use:
gradle :integTest \
-Dtests.class=org.elasticsearch.rest.PrometheusRestHandlerClientYamlTestSuiteIT \
-Dtests.method="test {yaml=resthandler/20_metrics/Prometheus metrics can be pulled}"
This plugin mainly uses the Prometheus JVM Client.
