Used for configuring elastic search.Once Exporter is configured, it can be started to scrape the elastic search and Next step is to configureĮxporter URL need to be configured with Prometheus for scraping the data from ES.The parameter “target” present in the following location should be configured with the required exporter. Among different parameters, “es.uri” is the parameter Exporter provides list of different configuration parameters. Helm charts and Docker images are also provided as a part of the Git repo.īasic Configuration: ( Exporter and Prometheus )Įlastic search URL need to be configured with the exporter for getting the required data points. The exporter “elasticsearch_exporte” is developed in Go and used for collecting various metrics about ElasticSearch. GET /_cluster/health/test1,test2, GET /_nodes/nodeId1,nodeId2/statsGET /_nodes/stats/indices, GET /_nodes/stats/os,process, GET _nodes/usageĮlasticsearch server can be monitored using Prometheus exporter, which is present in Prometheus repo. GET /_cluster/stats?human&pretty ,GET _cluster/health,GET _nodes/stats ,GET _nodes/hot_threads There are also different tools from different open source projects like cerebro, elasticsearch-head and Prometheus for monitoring elasticsearch server.Įlasticsearch Native monitoring( Marvel ) In the first place, Elasticsearch itself provides different REST APIs and tool (Marvel) for monitoring different stats like Nodes and Cluster Health, Unavailable Shards, Memory usage etc. Therefore elasticsearch performance and availability plays an important role and we would like to monitor the same. In my current Dev cluster, Elasticsearch server is used by Kibana for log monitoring, Any outage in Elasticsearch can impact the log monitoring in the cluster.
