[Xymon] Custom check interval for different status of custom tests

[Andrey Chervonets]

Really our situation is not so dramatic. per 5 min. tests will affect 
performance, but will not block anything.
We can allow it for short time, but we have to avoid unnecessary load 
during all the day.
In most cases fix delivered quite fast and it would be nice to have more 
accurate resolution time statistic.


Best regards,

If you re-run the checks more frequently when they fail, won't there be a 
performance impact?  If the failure is due to load, then you might end up 
making things worse.  Even if load isn't impacted, the people who are 
troubleshooting the problem might think your monitoring is the /cause/ of 
the problem, rather than a symptom.

I thought about trying to solve this in a generic way - having a script 
that looks for failures and does a re-test, perhaps for tests that are 
tagged for re-testing in hosts.cfg.  However, I realised that very few of 
my tests would benefit from this and not be at risk of causing increased 
load during a time of trouble.  Of those, I really would need to handle 
each one on a case-by-case basis, to determine an optimal balance of 
detecting resolution quickly vs limiting load caused by the tests.  As 
it's a case-by-case assessment, I thought a generic solution wouldn't be 
appropriate.
