Monitoring is an essential part of operating and observing Kubernetes clusters. Pipeline uses the CNCF graduated project Prometheus and Grafana to monitor Kubernetes clusters.
Collecting metrics with Prometheus 🔗︎
Prometheus is the most used solution to gather metrics from a Kubernetes cluster. By default it collects basic data from the nodes and kubernetes services.
Pipeline uses the Prometheus Operator to configure the different parts of monitoring. You can collect your own application’s metrics as well, just configure the ServiceMonitor custom resource for it. If you want to learn more about configuring Prometheus Operator please read the getting-started guide
If you enable monitoring, Pipeline installs the following components:
- Prometheus Operator
- Prometheus
- Alertmanager
- Basic Alerts (Cluster alerts)
- Basic Dashboards (Cluster metrics)
Dashboards 🔗︎
Pipeline provides Grafana dashboards out of box to overview your cluster and application health statuses. Each of the supported features comes with monitoring and dashboards as well.
