Method 1
- Go to the homepage of Grafana dashboards.
- In the left-side navigation pane, click the Explore icon.
- On the Explore page, select a cluster from the drop-down list. In the Metrics field, enter a PromQL statement and click Run Query in the upper-right corner.
For example, the PromQL statement to query the ratio of CPU usage to CPU Limit for each Pod is
(sum(rate(container_cpu_usage_seconds_total[1m])) by (pod_name) / sum(label_replace(kube_pod_container_resource_limits_cpu_cores, "pod_name", "$1", "pod", "(.*)")) ) by (pod_name)). Set Query type to Range. After execution, the CPU usage curves of each Pod are displayed as a line chart.
Method 2
Log on to the ARMS console.
- In the left-side navigation pane, choose .
- In the top navigation bar of the Prometheus Monitoring page, select the region where the monitored Kubernetes cluster resides. Then, click the name of the Kubernetes cluster.
- In the left-side navigation pane, click Service Discovery.
- Click the Targets tab.
- Click the show icon before a service name. Then, click the link in the Endpoint column of the table below the service name to view the collected metrics.
