Is there a way to be alerted if any core files are created in /var/core/
(Solaris 10)?  Just the presence of any core* file is sufficient.

Regards,

Hi Nick,

In the analysis.cfg file you can test for the existence or otherwise of a file or files. The section from the man page is:

----
     FILE filename [color] [things to check] [TRACK]

     DIR  directoryname  [color]  [size<MAXSIZE]   [size>MINSIZE]
     [TRACK]

     These entries control the status of the "files" column. They
     allow  you  to  check  on  various data for files and direc-
     tories.

     filename and directoryname are  names  of  files  or  direc-
     tories,  with  a full path. You can use a regular expression
     to match the names of files and directories reported by  the
     client, if you prefix the expression with a '%' character.
----
Since you want the non-existance of a core file to be green you could create an entry like this:

HOST=*
  FILE=/var/core/* red noexist

Which should report the FILE column as green if nothing exists in /var/core and red if anything appears.

I haven’t tried this so you may need to poke at it a little, but hopefully it will give you a starting point.

Hi

We do check for core files, and we do it as follows.

client-local.cfg
file: `/opt/csw/bin/sudo /usr/bin/find /var/core/ -type f 2> /dev/null`
This assumes appropriate sudo permissions are already set up for xymon user
on the client.

analysis.cfg
HOST=myserver
     FILE    %^/var/core/.* NOEXIST red

Salt to taste.

Cheers
V

Thanks!  It is now working.

However, when there are no core files, the alert symbol is white and sad.
How can I make it green and happy please?

That's odd. It's green for me.

But we are also checking a few things for other files too.
Might be a minor bug - if no file data comes through, it assumes no checks
- hence white.
Can you add a check for the existence of a file. Something that will
ALLWAYS be there, like /etc/passwd or similar.

If that works, you can leave it as a workarround, or talk to Henrik about a
minor bug fix.

Cheers
Vernon
