You could use md5 but if the config file has other changes that you don't care about then this wont work.  Unless there is only one value that changes I don't see any other option except an external test, which whould be easy to implement.


What would be really useful, I think, is the ability to specify a custom hash command using backticks.  Something like this:


client-local.cfg:
    file:/path/to/file:`/usr/bin/sed -n '/^var=/s/^var=//p' /path/to/file`


analysis.cfg:
    HOST=blabla
        FILE /path/to/file HASH="foo"

Jeremy, 

Both pretty cool ideas, never knew about linecount.  Then, I'm still on 4.2.0 so there's alot I don't know :)
External scripts work fine for me, but I like the integration that Xymon now gives out of the box.

Thanks,
