James Hofer over at PowerWF has posted his first blog article, it points out how to report the virtual machine snapshot age. He has created a step by step tutorial how to create the PowerWF workflow.
VMware provides a relatively easy way to script virtual machine management using PowerShell with PowerCLI. Unfortunately there is still a significant learning curve for someone with minimal PowerShell experience; not realizing a connection to the virtual center or ESX host is required before executing other commands, or that failure to close that connection in a script leaves the connection open indefinitely can be very frustrating.
Fortunately PowerWF simplifies this process significantly. One problem VMware administrators face is finding old virtual machines snapshots that are wasting storage space. The following example takes advantage of both PowerShell and PowerCLI to find outdated snapshots and email the results. To begin, create a new workflow project named, “SnapshotAge”.
