sorry for bothering, but i have a question regarding mongodb_exporter and dashboards.
I assumed that this may be used without anything else in between, simply by installing & configuring the exporter and using the exported metrics via grafana.
Sadly if i try to use a dashbaord, for example: grafana-dashboards/MongoDB_Instance_Summary.json at main · percona/grafana-dashboards · GitHub
there always is only dummy data (random walk).
I already tried changing the datasource before improting and also replacing
Am i simply wrong that this can be used in this way, or am i missing anything?
Grafana version: 8.1.2
mongodb-exporter version: 0.20.5
dashboard version(s)/branch: master, but also tried v2.19.0
Maybe somebody may give me a hint/advice?
Thanks in advance!
