2023-01-06 12:00:29
需求
收集 ES 的指標, 並進行展示和告警;
現狀
- ES 通過 docker compose 安裝
- 所在環境的 K8S 叢集有 Prometheus 和 AlertManager 及 Grafana
方案
複用現有的監控體系, 通過: Prometheus 監控 ES.
具體實現為:
採集端 elasticsearch_exporter
可以監控的指標為:
| Name | Type | Cardinality | Help |
|---|---|---|---|
| elasticsearch_breakers_estimated_size_bytes | gauge | 4 | Estimated size in bytes of breaker |
| elasticsearch_breakers_limit_size_bytes | gauge | 4 | Limit size in bytes for breaker |
| elasticsearch_breakers_tripped | counter | 4 | tripped for breaker |
| elasticsearch_cluster_health_active_primary_shards | gauge | 1 | The number of primary shards in your cluster. This is an aggregate total across all indices. |
| elasticsearch_cluster_health_active_shards | gauge | 1 | Aggregate total of all shards across all indices, which includes replica shards. |
| elasticsearch_cluster_health_delayed_unassigned_shards | gauge | 1 | Shards delayed to reduce reallocation overhead |
| elasticsearch_cluster_health_initializing_shards | gauge | 1 | Count of shards that are being freshly created. |
| elasticsearch_cluster_health_number_of_data_nodes | gauge | 1 | Number of data nodes in the cluster. |
| elasticsearch_cluster_health_number_of_in_flight_fetch | gauge | 1 | The number of ongoing shard info requests. |
| elasticsearch_cluster_health_number_of_nodes | gauge | 1 | Number of nodes in the cluster. |
