Troubleshoot Grafana Dashboard

General Grafana dashboard troubleshooting topics

Ceph - OSD Overview Dashboard: 3 panels not found

This means that the cray-sysmgmt-health pie chart plugin is not installed. If the system is not airgapped, then it can be installed by commenting out or removing the plugins property in customizations.yaml. This will be fixed in a future release.

(ncn-mw#) Command to extract customizations.yaml from the site-init secret.

kubectl -n loftsman get secret site-init -o jsonpath='{.data.customizations\.yaml}' | base64 -d - > customizations.yaml

Example:

cray-sysmgmt-health:
          grafana:
            externalAuthority: grafana.cmn.{{ network.dns.external }}
            plugins: ""

In the above section, comment or delete the plugins line in order to install the pie chart plugin.

(ncn-mw#) Upload customizations.yaml file to Kubernetes so that the changes persist.

kubectl delete secret -n loftsman site-init
kubectl create secret -n loftsman generic site-init --from-file=customizations.yaml

Ceph - RBD Overview Dashboard: No Data

This means that the Grafana dashboard is not getting any ceph_rbd_* metrics from the Ceph exporter. This will be fixed in a future release.

Ceph - RGW Instance Detail Dashboard: Panel missing and no data

Ceph - RGW Instance Detail Dashboard uses a 30 second time range in queries, which is a very short duration. Because of this, the dashboard is unable to load the data. This will be fixed in a future release.
