Custom variable type not working. Does not narrow down resources

[joperez08]

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.

• What Grafana version and what operating system are you using?
  Grafana v7.3.0

• What are you trying to achieve?
  I am trying to narrow down the top resources and not have all resources appear in panels.

• How are you trying to achieve it?
  Using a Custom variable that helps narrow down the top resources

• What happened?
  It does not narrow down the resources.

• What did you expect to happen?
  I expected it to narrow down the results.

• Can you copy/paste the configuration(s) that you are having problems with?
  Datasource is Prometheus
  query: topk($TopResources, netapp_volume_avg_latency{datacenter=“$Datacenter”,cluster=“$Cluster”,svm=~“$SVM”,volume=~“$Volume”})
  

• 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?
  Nope

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?
