I'm interested in visualizing some performance metrics of my Pyramid app.
1. Average, min and max response time per route group (eg. interface
views vs API calls)
2. Optimal threads per process ratio
3. Backlog size
I'm using uwsgi. I've found this:
http://projects.unbit.it/uwsgi/wiki/ManagementFlag
from which it seems I can monitor the backlog and then some.
For #1, I thought to write a simple tween that would write realtime
stats to memcached, to be read every 5 minutes by munin for some nice
graphs. I can also graph the uwsgi backlog (also there appears to be
some munin plugins for this).
I'm not quite sure what to do for #2. I guess the easiest thing is start
with some numbers and observe graphs for #1 and #3, change the thread
per process ratio periodically and observe whether there's improvement
or degradation in graphs.
Advices? Suggestions?
Thanks,
