Since ElasticSearch 6.0.0 :
./bin/elasticsearch-plugin install -b https://distfiles.compuscene.net/elasticsearch/elasticsearch-prometheus-exporter-6.2.2.0.zip -
On ElasticSearch 5.x.x :
./bin/elasticsearch-plugin install -b https://distfiles.compuscene.net/elasticsearch/elasticsearch-prometheus-exporter-5.6.4.0.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 installation !
Note that the plugin needs 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 irelevant, you can disable in the main configuration file:
prometheus.indices: false
-
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 address :
http://<your_server_address>: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_gc_collection_time_seconds{cluster="develop",node="develop01",gc="old",} 0.0
es_jvm_gc_collection_time_seconds{cluster="develop",node="develop01",gc="young",} 0.0
# HELP es_indices_requestcache_memory_size_bytes Memory used for request cache
# TYPE es_indices_requestcache_memory_size_bytes gauge
es_indices_requestcache_memory_size_bytes{cluster="develop",node="develop01",} 0.0
# HELP es_indices_search_open_contexts_number Number of search open contexts
# TYPE es_indices_search_open_contexts_number gauge
es_indices_search_open_contexts_number{cluster="develop",node="develop01",} 0.0
# HELP es_jvm_mem_nonheap_used_bytes Memory used apart from heap
# TYPE es_jvm_mem_nonheap_used_bytes gauge
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
- node1:9200
- node3:9200
Of course, you could use a 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.
