Filter out zeros before applying an increase

[Tim Harrison]

I have a "bad" counter that I'm trying to apply an increase to.  That counter occasionally does not appear on the exporter page for various reasons and so prometheus records it as a 0.  Due to this, the data appears to go 1000,0,2000,2500,0,3000,3500 and so on.  When I apply an increase, i get these huge spikes because every time a zero occurs, it thinks the increase is from 0 to 3000 rather than from 2500 to 3000.  I need to figure out if there's a way to filter out the zeros (or make them equal to the last non-zero value) before applying the increase function.  Thanks.

rate((counter > 0)[20m:])

Subqueries can help but you will stumble upon many other issues with this. Please try to fix the exporter.
