Whether your developers are keeping snapshots around for months or your backup program is leaving behind old snapshots due to backup failures, its always good to know about your aging snapshots.
Below is a script which will find all VMs with snapshots older than 7 days. As usual you can customize this to meet your needs, for me I like to keep transcripts and output files for archival and troubleshooting.
