In addition to setting up and using Tanzu Observability as a Wavefront Query Language data source in Grafana, you can also use Tanzu Observability as a Prometheus data source in Grafana.

When you set up Tanzu Observability as a data source in Grafana, you can view the data stored in Tanzu Observability by using the Grafana GUI.

How to Use Tanzu Observability as a Prometheus Data Source

To use Tanzu Observability as a PromQL data source, make sure that PromQL support is enabled on your cluster.

You can now test and see that a PromQL query in Tanzu Observability returns the same result as a PromQL query in Grafana when the data source is the Tanzu Observability cluster that you have configured.

  • A PromQL query in Tanzu Observability:

    PromQL query in Wavefront

  • Same PromQL query in Grafana when the data source is the Tanzu Observability cluster that you have just set up.
