1. How do I export profiling data I have already generated using Omniperf?

In order to interact with the Grafana GUI you must sync data with the MongoDB backend. This interaction is done through database mode.

Simply pass the directory of your desired workload like so,

$ omniperf database --import -w <path-to-results> -H <hostname> -u <username> -t <team-name>
