Well, I think these tests are coded on the server, and then fetched by the client and implemented at the client level. Under perfect conditions it can take 10 or 15 minutes for the client to retrieve and implement any changes. However, if you have coded everything correctly (like there is no mismatch on your host name, etc.) then there may be a problem with the client fetching mechanism. Since none of your stuff is working, it is hard to say whether the problem is in your configuration file (remember that Xymon silently ignores errors) or in the client itself.

Yes, I correctly configured hobbit-clients.cfg on the Xymon server (Linux host), 'cuz it works fine on the cluster's head-node, but not on any of the compute nodes. And it's not a "cluster" thing, 'cuz cpu, disk, memory, and messages all work fine on the compute nodes.

"Ports" says "No port checks defined", and "Procs" says "No process checks defined"; but, here are the entries for the first compute node:

HOST=node13.cluster.private PROC hobbitlaunch PROC sge_execd PORT "LOCAL=%([.:]22)$" state=LISTEN color=yellow TRACK=sshd "TEXT=SSHD Server"

However, clicking on the blinking white "Ports" LED displays the following:

No port checks defined

So we see that port 22 is being LISTENed on.

And, clicking on the blinking white "Ports" LED displays the following:

So we see that both the hobbitlaunch and sge_execd processes are present.

Thoughts? Suggestions?
