No data from Unifi in Grafana

Grafana Prometheus
1

Hi all,

I have Grafana, Prometheus and Unifi-Poller installed in a Portainer Stack on my NAS.

I have another Stack containing Unifi Network Application (UNA) that contains just one AP.

I’m trying to get the data from the UNA into Grafana and that seems to be happening as I can run queries via Explore and I’m getting results.

However, I have tried all the Unifi/Prometheus Dashboards at the Grafana Website and none of them show any data at all.

Are these Dashboards incompatible with UNA, or should I be doing this another way?

TIA

EDIT: Some Unifi-Poller log data:

Hi,
If the data is displayed in the Explore in Grafana, then the data is accessible in Grafana. What you need to do is check the variables of the dashboards you’re importing. Most of the dashboards have:

  1. Datasource variable (which might not have picked your datasource, hence provide “No Data”)
  2. Instance variable (which might have some obsolete metric name, hence yielding “No Data”)

If the first one is correct or the datasource variable is not present, check the second one. If it’s not present, check the queries of the panels - they might be using obsolete metric names. If it is there, execute the query in explore mode - does it yield any results? If so, what are the results and does the label required in the variable exist? If the query does not provide results, you need to debug why.

Thank you for your reply.

I have managed to find the issue with the no data. I had the incorrect Prometheus namespace name in my Unifi-Poller Portainer Stack. unifipoller, instead of unpoller.

Thanks again.
