missing disk detection
Is there any way to set up xymon so that it will detect a missing disk? I had a SAN disk on a Windows box go missing for an hour or so last night and it wasn't detected.
Thanks, Larry Barber
You should be able to set up a file check that verifies that a file on the SAN exists. If the disk is disconnected, the file check should go red.

Can you do that when the client is in "local" mode?

Yes, I think so, there are some extension scripts available for BBWin which can be used to do file checks on the client when running in local mode. I think one is even available in the installer "Fsmon" or something.

Write a script. Anything that you can run via the command line, can be scripted. Basically you do this:
run command that tells you about the disks
parse that output looking for error messages or bad words like "missing"
Send a message using bb (is that renamed xymon in 4.3.0 beta3?)
bb 0.0.0.0 "status+15m hostname MyDisks color output of command"
0.0.0.0 would be the ip address of your server if you only have 1 status+15m means every 15 minutes the server expects an update, otherwise it will go purple hostname is whatever is in bb-hosts (hosts.cfg) MyDisks is the name of your custom test that this script is running color - green|red|yellow any more output is optional, but very helpful in looking at the test's screen.
Then you can either run that script from a crontab or hobbitlaunch.cfg (xymonlaunch.cfg).

I have "tag" files, ".mounted" at the top of each native f/s mount, ".NFSmount" at the top of each NFS disk. ".CIFSmount" at the top of each CIFS disk. I test on ( I'm Linux so..) I test: 1) presence/readability 2) then, since a f/s fault will flip the f/s to read-only, writeability (echo date into it).
How you do this in windows is not my thing... #-------------------------------------------------------------------------------------------------------------- On 1/12/2011 3:16 PM, Larry Barber wrote:
