We’ll install all of Prometheus Operator’s Kubernetes custom resource definitions (CRDs) that define the Prometheus, Alertmanager, and ServiceMonitor abstractions used to configure the monitoring stack. Instead of having to modify a Prometheus configuration file, update a ConfigMap object, and roll out the new configuration, Prometheus Operator will automatically hook in new ServiceMonitors to your running Prometheus deployment. It sends http requests to target (scrapes) and the response (metrics data) it gets in response gets stored in storage (The time series database “TSDB”). http://prometheus-server.monitoring.svc.cluster.local. A working NFS server is required to create persistent … Horizontally scalable, multi-tenant log aggregation system inspired by Prometheus. You can create dashboards on Grafana for all the Kubernetes metrics through prometheus.
