Monitoring and Maintaining Elasticsearch 🛡️
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.
