Enhancement: Ability to filter out 'noise' by not reporting until N failed attempts, where N>1 #182

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
We see a lot of 'single failures' where a check fails for some reason unrelated 
to the check itself, only to return to "No problem" the very next check. This 
I'd call 'noise' and it causes a lot of unnecessary activity in the status bar 
making it grab attention and a waste of time checking what it reports.

The simplest solution is to require at least N failures before reporting the 
issue, the current default being N=1. This count is readily available in the 
status page being checked.

I'd personally change N to 2 and almost all the noise goes away. It will cause 
a delay until a real issue is reported (N * update interval) but that is 
trivial, especially compared to the time saved from checking on stuff that 
hasn't really failed.
