This shell script uses the output of the "find" command (published via snmp to avoid check_by_ssh or NRPE) to locate all the existing snapshots. It checks the size of each snapshot and based on your criteria sends a CRITICAL or OK status. Helps find forgotten snapshots that are growing out of control before they become a problem.
Inspired by "jacob"'s script check_snmp_snapshot.sh.

Nagios check script for vmware snapshots sizes

add the following to your ESX server in the /etc/snmp/snmpd.conf and restart the snmpd deamon
exec .1.3.6.1.4.1.6876.99999.2 snapshots /etc/snmp/snapshots.sh

If that OID is in use, increment the last number and modify the 'snmpwalk' line accordingly

snapshot.sh should contains these lines.
#!/bin/sh
/usr/bin/find /vmfs/volumes/ -name '*delta*.vmdk' -printf %f' '%s'n'

make sure it's executable by using the following command
chmod a+x /etc/snmp/snapshots.sh

Call this command as follows:
check_snmp_esx_snapshots.sh [devicename] [snmp read community] [crit]

So far the script doesn't support a WARNING level, only CRITICAL and OK.

Tested with ESX 3.5 and Nagios 3.0.3 running on OpenBSD 4.4
