Hi.
I would like to monitor UDP ports as TCP ports, with the client module,
and a display in the "ports" column. I don't understand why this module is
limited to TCP connections, and I would like to extend it to active UDP
connections.
Why does the client module run a "netstat -ant" command (file
"xymonclient-linux.sh")? Is there a reason not to add UDP connections as
well?
UDP doesn't have "connections" as such, so you will only be able to list the ports where there is a local process listening for incoming datagrams.
That might make sense in some cases, but you can usually do this just be looking for the right process to be running.
What would be the best solution? Clone the section and run a "netstat
-anu"? Patch the existing client and run "netstat -antu"? Another solution?
I tried with the Linux client, and you can change the existing client code to run "netstat -antu" instead of just "netstat -ant" - this won't cause any problems.
I am not sure if the server-side of the client will be able to pick up those UDP ports, because they haven't got anything in the "State" column. You'll have to try that.
