1. How do I export profiling data I've 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>

2. python ast error: 'Constant' object has no attribute 'kind'

This comes from a bug in the default astunparse 1.6.3 with python 3.8. Seems good with python 3.7 and 3.9.

Workaround:

$ pip3 uninstall astunparse
$ pip3 astunparse

3. tabulate doesn't print properly Workaround:

$ export LC_ALL=C.UTF-8
$ export LANG=C.UTF-8
