Best way to do total count in case of counter reset ?

See original GitHub issue

I am using prometheus + grafana, and wrote a simple query like sum(increase(some_count[$__range])) , although this takes the difference between the first and last values, seeing prometheus values gets restart on restart of our node server, any better approach to tackle this problem ? Sample graph explaining the drop due to server restart

Just to leave this here:

sum by (label) (increase(metric[$__range]))

Is what I was looking for when I came here via search.

@somyarocketium With prometheus + grafana I believe you can get the grand total of all increase in the current window by using the legend. You can do something like this Query: Screen Shot 2021-03-31 at 1 50 13 PM Setting $__interval will automatically use the minimum x-axis time unit based on your window resolution. $__interval is an auto scaling feature you can use with prometheus + grafana. Make sure to also set min step to 1m.

Visualization > Legend Screen Shot 2021-03-31 at 1 50 26 PM The total that is reflected in the legend will be the total increase that happened in your window. This should work regardless if a counter reset happened
