Monitoring and Maintaining Elasticsearch 🛡️

Advanced

Maintaining a healthy Elasticsearch environment involves monitoring key metrics:

  • Cluster health and status
  • Node CPU, memory, and disk usage
  • Indexing and search latency

Use tools like Kibana’s Monitoring UI or Elasticsearch APIs:

GET /_cat/health
GET /_cat/nodes?v
GET /_cluster/stats

Regular snapshots and index lifecycle management (ILM) help in data retention and disaster recovery.

Automate alerts for abnormal behavior, and schedule routine maintenance, including index optimization, shard reallocation, and plugin updates. Proper maintenance ensures sustained performance, reliability, and security of your Elasticsearch cluster.
