Custom variable type not working. Does not narrow down resources

I have imported a dashboard and the custom variable ‘TopResources’ does not seem to be working. For instance, when I select ‘3’ for TopResources it does not narrow it down as expected. It still displays all the results instead of the top 3.

    Using a Custom variable that helps narrow down the top resources

    It does not narrow down the resources.

    I expected it to narrow down the results.

    Datasource is Prometheus
    query: topk($TopResources, netapp_volume_avg_latency{datacenter="$Datacenter",cluster="$Cluster",svm=~"$SVM",volume=~"$Volume"})
    CustomVar

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
    N/A

  • Did you follow any online instructions? If so, what is the URL?

Hi @joperez08

Welcome to the Grafana forum! Just to clarify: you said you imported a dashboard. Does the query work when you hard-code that value? Do the other variables work? Does this work:

topk(3, netapp_volume_avg_latency{datacenter="$Datacenter",cluster="$Cluster",svm=~"$SVM",volume=~"$Volume"})

It’s not uncommon for imported dashboard not to work right out of the box. Which dashboard did you import?
