New Features:

• Initial Grafana Dashboard that included sections for:

  • Cluster high-level status: Cluster health charts and basic node counts
  • Cluster shards: Number of cluster shards in individual states (active, initializing, relocating and unassigned)
  • Thread Pools: Internal Thread Pools stats
  • System: Basic Host system metrics provided as by OpenSearch
  • Document and Latencies: Document indexing, deleting and searching stats
  • Caches: Field data and Query caches stats
  • Throttling: Indexing and merging throttling
  • JVM: Basic metrics of cluster nodes JVM (Heap and GC)

• Initial Prometheus Alerts:

  • OpenSearchClusterNotHealthy: Cluster health status alert
  • OpenSearchBulkRequestsRejectionJumps: High increase in the node bulk request rejections count
  • OpenSearchNodeDiskWatermarkReached: High/Low disk watermark threshold has been reached on the node
  • OpenSearchJVMHeapUseHigh: High JVM Heap use on the node
  • OpenSearchHostSystemCPUHigh: Host system CPU load is high
  • OpenSearchProcessCPUHigh: OpenSearch process CPU load is high

Known issues:

• Cluster status chart does not correctly display the cluster health (ie: Green, Yellow, Red).
• Node DiskWatermark alerts use static thresholds value while they should be using node settings value exposed in metric (see relevant issue).
