Hi! Beautyful work!!!! I just have one question... I follow all the steps, but in prometheus I only get "mongoup" metric... no the full set of mongodb metrics. What could I been doing wrong??

[@avinashkumar-thelearningdest]

Thanks for valuable comments @pablo Sorry for delay in my response, Could you please check that the user "mongodb_exporter user has been successfully created and having correct permissions.

[@rappalini]

@@avinashkumar-thelearningdest I dont have a "mongodb_exporter" user, I only create thue user "prometheus" with this command: sudo useradd -rs /bin/false prometheus

[@rappalini]

I check, I have the user prometheus in the system, and the user "mongodb_exporter" in the DB Mongo... It has the same as the data you provided... What can be happening?

[@durantapatra443]

[@avinashkumar-thelearningdest]

I will brother. Thanks 😊

[@yarraramu4774]

can't we get data directly from mongoDB without using prometheus?

[@avinashkumar-thelearningdest]

I think, it can be as when you add Datasource "MongoDB" in Grafana. Bit I would recommend, go with Prometheus as you can easily track more then 100 metrics with prometheus.
