Pre-req:

• Install COO1.2.0 from OperatorHub just to have COO installed
• Patch COO CSV with monitoring-console-plugin image generated from this PR that contains the fix for #OU-814  https://github.com/openshift/monitoring-plugin/pull/448  (quay.io/rh-ee-emurasak/monitoring-console-plugin:ou814v04 or ou814v05)
• On COO, install these PersesDashboard in perses-dev namespace
  • • https://github.com/etmurasaki/dotfiles/blob/main/scripts/rbac/dashboards/perses-dashboard-sample.yaml
    • https://github.com/etmurasaki/dotfiles/blob/main/scripts/rbac/dashboards/prometheus-overview-variables.yaml
    • https://github.com/etmurasaki/dotfiles/blob/main/scripts/rbac/dashboards/openshift-cluster-sample-dashboard.yaml
    • https://github.com/etmurasaki/dotfiles/blob/main/scripts/rbac/dashboards/thanos-compact-overview-1var.yaml
  • create this datasource
  • https://github.com/etmurasaki/dotfiles/blob/main/scripts/rbac/dashboards/thanos-querier-datasource.yaml
• Install this PersesDashboard in openshift-cluster-observability-operator:
  • https://github.com/etmurasaki/dotfiles/blob/main/scripts/rbac/dashboards/prometheus-overview-variables.yaml with the spec.display.name including 1 Prometheus / Overview just to differentiate from the other namespace

Steps:

1. Log into ocp
2. Go To Observe > Dashboards (Perses)
3. Select 1 Prometheus / Overview dashboard
4. Switch to Perses-dev project
   1. Notice that the first time, Prometheus / Overview dashboard is "loaded"
5. Click on Dashboard dropdown: notice that Prometheus / Overview dashboard is the third in alphabetical order
6. Switch back to openshift-cluster-observability-operator project
   1. Notice only the Dashboard dropdown is updated with 1 Prometheus / Overview, but the whole page is the same

Note: When testing with the same dashboard name but different layout it causes problems, because the content is not reloaded correctly. See video attached.

1. Go To COO
2. PersesDashboards tab
3. Edit prometheus-overview for perses-dev namespace
   1. Under spec.layouts, remove the first Grid containing Prometheus Stats
   2. Save it
4. Go back to Dashboards (Perses) and switch between the 2 namespaces with Prometheus / Overview dashboard
   1. Result: Dashboards are now different in the layout, but both are presenting the same content

First time:

Second time: it maintained the last layout
