HanaDB Monitoring
KubeDB has native support for monitoring HanaDB via Prometheus. You can use built-in Prometheus discovery or Prometheus Operator to monitor KubeDB-managed HanaDB instances.
Before You Begin
- Deploy HanaDB first using the quickstart guide.
- Install Prometheus Operator or another monitoring stack that can scrape Kubernetes services.
Overview
When you create a HanaDB object with spec.monitor configured, KubeDB injects the HanaDB exporter sidecar into the database pod. KubeDB also creates a stats service named {hanadb-name}-stats for scraping the exporter endpoint.
Configure Monitoring
HanaDB monitoring is configured via spec.monitor.
| Field | Type | Uses |
|---|---|---|
spec.monitor.agent | Required | Monitoring agent type. Use prometheus.io/builtin or prometheus.io/operator. |
spec.monitor.prometheus.exporter.port | Optional | Port where the exporter sidecar serves metrics. Defaults to 9668. |
spec.monitor.prometheus.exporter.args | Optional | Arguments passed to the exporter sidecar. |
spec.monitor.prometheus.exporter.env | Optional | Environment variables set in the exporter sidecar. |
spec.monitor.prometheus.exporter.resources | Optional | Resource requirements for the exporter sidecar. |
spec.monitor.prometheus.serviceMonitor.labels | Optional | Labels added to the ServiceMonitor for Prometheus selection. |
spec.monitor.prometheus.serviceMonitor.interval | Optional | Scrape interval for Prometheus Operator. |
