Pearl Script for monitoring snapshots
Many VMWare admins may have experienced problems with VMWare snapshots specifcally when they become no longer visible in the VI Client. SnapHunter will create a report letting you know the status of snapshots on all your VM’s from the command line.
SnapHunter can be download from here >> http://engineering.xtravirt.com/products/phd-technologies/snaphunter.html
You will need to copy the tar.gz file to your server using something like WinSCP
To extract the tar type tar -zxf snap_hunter.tar.gz
Now enter the folder that has been created and make the pearl scipt executable by running the following command chmod +x snap_hunter.pl
You will now be able to execute the pearl script by running ./snap_hunter.pl
You will need to edit the config file in an editor like nano or VI to reflect your settings
To automate this you can run ./snap_hunter.pl -schedule, this will automaticlly create a crom job for you scheduled as you wish, for the username and password I would recommend you use a local administrator and password on your VC server.

Hi,
I implemented snap_hunter on esx 3.5 but now, that we upgrade to vSphere 4.0u2, don’t work anymore.
Script start running, and give some errors:
cat: /vmfs/volumes/477dfcc1-5c0f635a-2022-0

Search completed successfully. No VMs were found to currently have snapshots.
That VMs don’t stand on the host where I running snap_hunter. Also when I look for crontab job, created by “snap_hunter.pl -schedule” with user root, I can’t find it. I tried with a snapshot in a vm, and email still don’t work.
