RE: [xymon] Execute a script on the client side

["Ward, Martin" <Martin.Ward (at) colt.net>]

You can write a script that you must install on the client but which you can change the configuration parameters for on the server.

On the Xymon server edit the ~xymon/server/etc/client-local.cfg file and put in the entries you need passed to the client. I created my own entries for Solaris SMF daemons I wanted to monitor:

----
[jump.server.colt.net]
log:/var/adm/messages:10240
SVC:svc:/network/ssh:default online
SVC:svc:/site/apache2:default online
file:/var/adm/sa/.adm
file:/var/spool/lp/admins/.lp
----

All of this information is passed to the client.

In the client-side script you need to include code that reads the ~xymon/client/tmp/logftech.<hostname>.cfg file. I wrote the following:

----
SVCSCMD=/usr/bin/svcs
SVCFILE=/$BBTMP/svcs.$$
rm $SVCFILE.check >/dev/null 2>&1
SVCLIST=$SVCFILE.list

# Get a list of things to check for
grep "^SVC:" $BBTMP/logfetch.$MACHINEDOTS.cfg | sed "s/^SVC://g" >> $SVCFILE.check
----

Now I can specify on the Xymon server which SMF services are checked for on my clients.
