[Xymon] Where to find the latest hostdata (or: How to monitor one process on two servers)?

[Steven Carr]

You can get this using the xymon command e.g...

xymon $XYMSERVERS "clientlog hostname section=ps"

That will dump the [ps] section from the current client data, you can then
grep through that to look for the required process, repeat for the second
host and then hopefully you should know which one it's running on.
