It'd be good to have this feature working.

In the mean time, you could use "FILE" (in analysis.cfg) to check for the
existence of a file, and use a backtick command (in client-local.cfg) to
specify the filename only if it's a symlink.  Example:

analysis.cfg:

FILE /etc/.sudoers.local red

client-local.cfg:

file:`find /etc/.sudoers.local -type l`

If the file is a symlink, it will exist.  If it's not a symlink, the Xymon
client won't see it, and you'll get a RED as if it didn't exist.

Cheers
Jeremy

Is checking whether a file is symlink supported in analysis.cfg?  The
man page doesn't mention it but client_config.c does look like it
should work.

I have this in analysis.cfg
FILE /etc/.sudoers.local red type=symlink

My test goes red with the following statement:
File is a file - should be symlink

If I click on it, I see this:
[file:/etc/.sudoers.local]
type:100000 (file, symlink -> /bw/local/etc/.sudoers.local)
mode:440 (-r--r-----)
linkcount:1
owner:0 (root)
group:0 (root)
size:102

mtime:1377011564 (2013/08/20-15:12:44)

To prove it's a symlink:
# ls -l /etc/.sudoers.local
lrwxrwxrwx   1 root     root          28 Aug  2  2011
/etc/.sudoers.local -> /bw/local/etc/.sudoers.local

What am I doing wrong?

I believe this is a bug. Might never have really been fully implemented,
actually.

Can you try the following patch (untested) and see if it works for you?
