Monitoring and Alerting for Apache Solr with the Prometheus Stack
summary
Deploys a Prometheus stack via Helm with configurable retention (default ~30 days) and loads Grafana dashboards from configmaps. Metrics flow from Prometheus exporter per Solr Cloud which scrapes /solr/admin/metrics and transforms JSON with jq into Prometheus format; Prometheus discovers exporters via ServiceMonitor. Dashboards use PromQL for QPS, P95, cache, GC, CPU and disk; alerts are Prometheus rules (e.g. heap >90% for 15m, P95 >100ms for 10m) and alerts evaluated by Prometheus and routed by Alertmanager with grouping, inhibition and receivers.
