Alerting based on multiple hosts - is it possible?

Hello,

Say I have 3 servers

Srv1
Srv2
Srv2

Is it possible to configure an alert so that it will fire only when the CPU test for all 3 servers has gone yellow or red?
In other words, I don?t want Xymon to alert when one server or two servers are having problems. Only when all three are.

Thanks,

You can do this via a combo test defined in combo.cfg

https://xymon.sourceforge.io/xymon/help/manpages/man5/combo.cfg.5.html

i.e. you could define something like..

servers.cpu = (srv1.cpu + srv2.cpu + srv3.cpu) > 1

or perhaps...

servers.cpu = (srv1.cpu || srv2.cpu || srv3.cpu)

which would be green if one or more of the individual cpu tests were green. You could then alert on "HOST=servers TEST=cpu" as normal.

Regards,

Adam

Yes, that is it! Thank you very much.

I apologize for the way my emails show in this list. I haven't figured out how to avoid that.
