I should have mentioned on the below description that I am still running
this at 5 minute intervals but just using it for a bigger timeout as I have
one test that can be a bit slow. It’s actually an http test that can take
more than the standard timeout. ****
** **
I’m sure this should be adaptable to SSH tests.****

** **
I do this for certain ping tests.****
** **
I have a slowtests.sh script in my ext directory like this,****
** **
#!/bin/sh****
** **
XYMONNETWORK="slowtests"****
export XYMONNETWORK****
** **
$XYMONHOME/bin/xymonnet --report --ping --checkresponse --timeout=20****
** **
** **
Then my tasks.cfg has been changed so that xymonnet has the –test-untagged
option,****
** **
[xymonnet]****
ENVFILE /xymon/server/etc/xymonserver.cfg****
NEEDS xymond****
CMD xymonnet --report --ping --checkresponse --test-untagged****
LOGFILE $XYMONSERVERLOGS/xymonnet.log****
INTERVAL 5m****
** **
And I have a new entry at the bottom like this,****
** **
** **
[slowtests]****
ENVFILE /xymon/server/etc/xymonserver.cfg****
NEEDS xymond****
CMD $XYMONHOME/ext/slowtests.sh ****
LOGFILE $XYMONSERVERLOGS/slowtests.log****
INTERVAL 5m****
** **
** **
Then all I do is add the tag “NET:slowtests” to the tests that I only want
to run every 20 minutes.****
** **
I must admit though, that I’m not sure if xymonnetagain would still pick
up a failure from slowtests and start the 1m retries. ****
** **
Perhaps someone else can help on that. ****

** **
Hiya****
** **
I have a few devices on which I do an ssh check. These devices have some
sort of self-defence mechanism and they throttle connecting to the sshd
process if they get failed connections (with no login) at too high a rate.
Unfortunately, twice every 5 minutes (I have two Xymon servers) is
sometimes a bit too often, and once they start to fail, I'm guessing that
xymonnet-again.sh starts to hammer them every minute. The devices are
appliances such that I cannot configure this behaviour.****
** **
I know there's a funky NET:location hack that can be used to adjust the
frequency of the net tests for nominated hosts, but I see no way to limit
the effect to only the ssh test, and so all tests will be slowed down.****
** **
Can anyone think of a better way to do this than the NET:location hack? I
only want to slow down the ssh tests.****
** **
Cheers****
