However, the WMI exporter should now run as a Windows service on your host. Is there a way to query kubernetes deployment metrics and make a dashboard with them for : cpu/memory/disk-usage by kubernetes-DEPLOYMENT? We can leave all that at default - it will work for our purposes. Select Prometheus. In the data source list, click the data source that you want to turn on caching for. The following query should return per-pod RSS memory usage: sum (container_memory_working_set_bytes {container_name!="POD",pod_name!=""}) without (container_name) If you need summary CPU and memory usage across all the pods in Kubernetes cluster, then just remove without (container_name) suffix from queries above. container="" <- part . We would really like to use Grafana for logs, but it is very difficult to do when the logging system crashes every 5 minutes after consuming all available memory. You can also use PromQL to create dashboards using the collected data and point it to an instance of Grafana or a hosted monitoring tool such as OpsRamp that natively supports PromQL. 1 - Building Rounded Gauges. Press the Enable button. This part of the demo shows how to define an alert for sustained high memory usage on the database, using the Grafana alerting parameter FOR. The parameter FOR specifies the amount of time for which an alert rule must be true before the ALERTING state is triggered and an alert is sent via a notification channel. I have the metric container_memory_working_set_bytes available from prometheus.Using only this metric how can i calculate the total memory used by a node which contains various containers. Another one of Grafana's key use cases is its capability for container monitoring as shown in the example above regarding Docker monitoring. Parameter Name. To run Grafana we will use the same approach as with Prometheus. the Load average figure is higher than the number of CPUs on the nodes, the service might be under-provisioned. For example its easy to graph all ping services in a single query: For example, SEARCH ('{AWS/EC2,InstanceId} MetricName="CPUUtilization"', 'Average', 300) (Optional) To add another search . . I have a SQL performance tool grafana which shows CPU usage very less than what i see in task manager.
