External scripts for Xymon client on Xymon Server
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
Hi all,
I am not sure what is the correct way to add external scripts to a client instance running on a machine that houses a server. If you look in hobbitlaunch.cfg in the server's etc directory, you see:
"hobbitclient" runs the Xymon client. The client is installed
automatically when you install a Xymon server (presumably, you do
want to monitor the Xymon server ?), but there's no need to have two
hobbitlaunch instances running at the same time. So we'll just run it
from here.
Note: If you are using another client package, you should disable this
one.
[hobbitclient] ENVFILE /opt/xymon-4.2.3/client/etc/hobbitclient.cfg NEEDS hobbitd CMD /opt/xymon-4.2.3/client/bin/hobbitclient.sh LOGFILE $BBSERVERLOGS/hobbitclient.log INTERVAL 5m
...however, if I do this, it appears as if either none of the external scripts run, or if they do run, they don't write anything to the logfiles/do not get their information to the Xymon server program.
Do I need to add the external scripts to hobbitlaunch.cfg instead of clientlaunch.cfg? Something else?
Thanks in advance for any help!

The clientlaunch.cfg is in the client's etc dir, not the server etc dir. Logs / tmp files will be under the client dir too.
Example, on a hobbit server there are both $hobbithome/{server,client} dirs.
client/ext/na2.sh
[client/etc] tail clientlaunch.cfg
[NA2CPU] ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg CMD $HOBBITCLIENTHOME/ext/na2.sh LOGFILE $HOBBITCLIENTHOME/logs/na2.log INTERVAL 2m

Yes, that much I knew. OK, so I've taken another look at this. It looks as if the external client scripts ARE running, but the data doesn't go anywhere and there are no ghost clients. I've also checked what I believe are all of the places that the port and server address are defined to make sure this isn't all going someplace else.
One of my external scripts, for example, is a vmio script. You can see it is running the commands needed to accomplish that:
xymon 4976 4973 0 17:50:09 ? 0:00 vmstat 300 2 xymon 4978 4975 0 17:50:09 ? 0:00 iostat -dxsrP 300 2
...however, about 6 months ago, these tests turned purple (to me, what seems like by magic). The other external scripts (one that gets temperature and one that does metastat for the SW raid) run too quickly for me to tell what their story is, but they do not write anything to the client log directory.
Anyone have any idea how to troubleshoot this?

You probably have a log file somewhere. In Tim's example, it defined like this:
LOGFILE $HOBBITCLIENTHOME/logs/na2.logIf the log doesn't show anything interesting, you should be able to *make* it show something interesting. For example, a "set -x" at the top of the script will show you exactly what it does.
You can also execute the script manually as if it were Xymon executing it, using the bbcmd command.

I always used to use cron to run extra checkout scripts - it takes the guesswork out of scheduling a lot of scripts.

This always confused me. In beta2 I run the client tasks specified in client/etc/clientlaunch.cfg
in beta3 I run the client tasks specified in server/etc/tasks.cfg it's even a note in tasks.cfg
client tasks are configured here, apart from the normal builtin that runs
from xymonclient.
I'm not sure which method is the correct one in beta2, the note in beta3 tells me that is the correct method for beta3.
