Alert Notifications 🔗 link

Hi,

I am planing to reconfigure xymon to send me an alert if a Server is going down.

Actually I am getting alerts for every service that is down but if a Server crashs, of course there are more than one service that switch to red. To get 6 SMS because 1 Server is down is a waste of money.

Is there a chance to configure xymon like this in the alerts to get only 1 alert if a Server goes down?

Kind regards,

Pascal Jarosch

Hi,

Please discard my Mail I sent from a wrong identity (which is being hold
right now).

To add some more detail to our problem:
Is it possible to define dependencies for alerts?
I saw following problem. If Router X is down all Services behind that
router will be notified. That's very annoying and I want to prevent
that. Notifying me, that Router X is down is enough.

Same for host connections. If a host is down I just want to get the host
down alert. Furthermore is there a feature like "don't notifiy me if
host/Service was red in <period>"?

I did not found any suitable option for that so far.
I hope you can help us out.

Thanks and best regards
Marvin Stark

There are two features in Xymon that are relevant to your quest:

1) Xymon's network tests (ssh, telnet, smtp, etc) are all conditional on a
successful ping response.  If a server crashes, then ping will fail, and
the "conn" test will go red, but also, all of the network tests will go
clear.  In such cases, Xymon will alert on the "conn" failure but no other
network tests.  Other tests that are not implemented by xymonnet will still
go red and still cause alerts.

This is the default behaviour.  You can disable this behaviour by using the
"noclear" or by prefixing a test name with a tilde, like "~ssh".

Look for "noclear" in the man page for hosts.cfg

2) You can configure router dependencies in Xymon.  For example, if host1
is connected via router1, then your host1 entry in hosts.cfg might look a
bit like this:

192.168.1.10 host1 # ssh telnet route:router1
192.168.1.1 router1 # ssh

If router1 is down, then any network tests for host1 will be changed from
red to yellow.  Read the man page for hosts.cfg for more information on the
"route:" specification and function.

3) When Xymon detects that a host is down due to a ping (conn) failure, any
client statuses (eg CPU usage, disk space) are prevented from going purple
and instead go clear.

4) You can specify a "depends" clause to define dependencies.  See the
hosts.cfg man page for this.

Also, Xymon supports suppressing alerts for a period of time, using the
"delayred" and "delayyellow" parameters.  Refer to hosts.cfg man page for
more.

Cheers
Jeremy

And by "two", I obviously meant "five".  The fifth feature is where you can
create combo tests, and adjust the alerting based on the result of boolean
tests.  For example, if you have router1 ping test and server2 http test,
you can do this in combo.cfg:

router1\-server2.web = (router1.conn==1 && server2.http==0)

Then configure your alerting to not alert for server2.http and instead only
alert for router1-server2.web.  Then you will only get an alert if the
router is up and the server web service is down.

To see the status of the combo test, you need to create a pseudo-host entry
in hosts.cfg for "router-server2".  More info in combo.cfg man page.
