Created attachment 1702075 [details] Misleading values in "PCP Vector Container Overview" dashboard Description of problem: When there is no container running on a host system, Grafana shows in the default "PCP Vector Container Overview" dashboard misleading values (see the screenshot in attachment). Version-Release number of selected component (if applicable): * grafana-6.7.4-1.el8 * grafana-pcp-2.0.2-1.el8 * pcp-5.1.1-3.el8 How reproducible: always Steps to Reproduce: 1. Install pcp, grafana, grafana-pcp components 2. Start pcp (pmcd, pmproxy) and grafana 2.1 Make sure there is no container running on the system - "podman ps" Should return nothing 3. In grafana, enable the "Performance Co-Pilot" plugin 4. In grafana, configure the Vector datasource using default values 5. Check charts in "PCP Vector Container Overview" dashboard Actual results: * Charts in the "PCP Vector Container Overview" dashboard are showing a lots of misleading values even no container is running on the host system Expected results: The dashboard (or the charts) stays empty as there is nothing to show Additional info: In case there is at least one container running on the monitored system, the dashboard shows correct/expected values.
