Hi all,
I suspect I know the answer to this but want to check:
I'm running Xymon 4.3.12. My manager has recently brought up the need to have the clock drift monitored (it caused problems with
a DB server when there was massive drift once for some reason).
I looked into how to do this and it looks like the highest level that clock drift can cause Xymon to alert at is yellow. This means that if I wanted to be alerted, I'd have to also get alerted for yellow CPU on that machine, right? So far my only idea is to raise the yellow level for CPU. I don't really want
to bother with an external test.
Any tips?
According to http://www.xymon.com/xymon/help/manpages/man5/analysis.cfg.5.html you should be able to add a line like
CLOCK 15 red
... to an analysis.cfg file (or *.d/ entry) to have it go red if the clock delta exceeds that absolute value. I have to admit not having tested that ever though.
If that doesn't work, you might be able to simulate it (or assign the color to a different test entirely) with a DS entry; something like:
DS cpu clock.rrd:la <-15 COLOR=red "TEXT=System clock is &V
seconds off" DS cpu clock.rrd:la >15 COLOR=red "TEXT=System clock
is &V seconds off"
Wonderful! I must have been reading an old copy of that documentation
(Google'd for it instead of using what was on the system). Thanks Japheth!
