Grafana GUI documentation unclear

Issue: to upload a database to our MongoDB server I was running

omniperf database --import -H <host_ip> -u admin -t asw -w workloads/devito_iso/mi200/

Pulling data from  /app/workloads/devito_iso/mi200
The directory exists
Found sysinfo file
KernelName shortening enabled
Kernel name verbose level: 2

ERROR: Unable to connect to the server

After a short while (but still, order of minutes) I realised that -u admin was wrong -- because admin is what was used for for the Grafana service, not MongoDB. For someone like me who didn't (doesn't) know anything about Grafana and MongoDB perhaps a bit more justified to be confused...

So then I started following the docs, strictly, that is I started using -u temp. However I was then prompted for a password. (Much) later on, I realised the the MongoDB password was hardcoded in the Dockerfile. This could be improved I think, I think two-three more lines in the docs would be enough.

This was co-debugged with @ggorman -- just to be sure it wasn't me having an unlucky day

Thanks for sharing this feedback, Fabio. I see how these differing credentials could make things confusing.

We'll add some clarification to the docs.

The Grafana GUI Import section has been updated

Default username and password for MongoDB (to be used in database mode) are as follows:

Username: temp Password: temp123
