Hello,
we have a counter metric that counts each time a pod is doing a
specific action.
I need to count how many times the pod (actually sum of all the pods
from a certain deployment) did the action over 24 hours.
problem is, the pod is on spot, and when it gets restarted, the
counter resets, so the metric might be 20 at 1:00, but at 2:00 it
might be 3, so when I try to do delta, or sum over time, I am getting
wrong results..
any ideas how can I get the real delta for the action in a 24 hours range?
Look at using rate() which handles counter resets. If you multiply the
value produced by the time period it is over you would get the number of
actions that occurred. Note that this will only ever be an estimate (for
example you might not scrape a pod before it is destroyed, missing the
detection of some actions) and will most likely not be an integer (due
to the way interpolation happens).
