I added two panels: 1- uwsgi busy workers. It's useful 2- average response time.

These two links helped me a lot:

• https://github.com/xrmx/uwsgitop/blob/master/uwsgitop

We can also RSS and VSZ too (memory footprint by uwsgi) but first, we need to enable --memory-report) @Halfak: Do you think we would need such metrics? if yes, tell me and I make the patch.

RSS would be nice to have. That the resident memory usage and it represents the stuff that I've been measuring to track our memory usage over time.

Change 305611 had a related patch set uploaded (by Ladsgroup):

Who deleted the average response time graph and why? (Why grafana does not have history)

I'm not sure how that got removed, but I did remove the VSZ graph since VSZ is a confusing if not misleading stat.
