Elastic Search Monitoring
Elasticsearch is an open-source, distributed, RESTful search and analytics engine capable of addressing a growing number of use cases. Moein provides the ability to monitor this ELK stack member (a collection of three open-source products: Elasticsearch, Logstash, and Kibana) in the NoSQL database category, supervising performance indicators and parameters such as cluster status, cluster nodes, thread pools, and shards. The performance metrics supported by Moein are presented below.
