Unable to see metrics on Grafana dashboard

Problem: You're unable to see metrics on the Grafana dashboard. When you check the logs, the following exception is displayed:

[console] Error creating stats.timers.view.graphite.errors.POST.median: [Errno 28] No space left on device
[console] Unhandled Error



The below solution steps are applicable to Grafana deployed in a Kubernetes environment.

Increase the persistent volume claim (PVC). To do so, follow these steps:

  1. Open vars.grafana.yml.

    cd ~/privacera/privacera-manager/
    cp config/sample-vars/vars.grafana.yml config/custom-vars/
    vi config/custom-vars/vars.grafana.yml         
  2. Add the GRAFANA_K8S_PVC_STORAGE_SIZE_MB and GRAPHITE_K8S_PVC_STORAGE_SIZE_MB two properties. The property values are in megabytes (MB).

  3. Run the update.

    cd ~/privacera/privacera-manager/
