Connecting Prometheus to Kubernetes, OpenTelemetry, Grafana and the exporters that bring infrastructure and databases into monitoring.
Running Prometheus on Kubernetes with the Prometheus Operator and kube-prometheus: ServiceMonitor and PodMonitor discovery, PrometheusRule alerting, Alertmanager configuration and retention and replica settings as code.
Sending OpenTelemetry metrics straight to Prometheus through its OTLP receiver: enabling the endpoint, out-of-order ingestion for collector replicas, promoting resource attributes and choosing a name translation strategy.
Pairing Prometheus with Grafana: the Prometheus data source, dashboards built on PromQL, Grafana alerting versus Alertmanager, and pointing the same dashboards at Thanos or Mimir when storage scales out.
Covering servers, endpoints and network devices with the official node, blackbox and SNMP exporters: probe design, module configuration and protecting exporters that take targets from URL parameters.
Monitoring PostgreSQL with the community postgres_exporter: least-privilege pg_monitor access, collectors for replication, WAL and statements, alert rules for lag and connections, and dashboards.
