The availability of vMotion and svMotion, provided you have a license that allows it, in vSphere are some of its key features.
The DRS and SDRS functionality will use vMotion and svMotion to better use the available resources.
And you as a vSphere administrator can use it to facilitate your work. Just think of how easy patching or datastorecluster maintenance becomes with the help of these two features.
But as an administrator you want to be able to report on what vMotion and svMotion have been doing over a specific time interval in your vSphere environment.
In the past I already provided a vMotion reporting tool in Events – Part 8 – vMotion history, but now it was time to provide a universal (s)vMotion reporting feature.
Update October 29th 2013: added additional parameters to the Get-VIEventPlus function
User: one or more users for which to return the events
System: a switch to return all system user events
ScheduledTask: return all events for a specific Scheduled Task
A single vMotion can now scale over multiple NICs. This feature can use a regular vSwitch or distributed vSwitch.On YouTube there are 2 videos, uploaded by VMwareKB, that show how to configure such a vMotion enabled multi-NIC vSwitch, regular and distributed.
Very useful videos, but as you can imagine, I wanted to automate this. No GUI clicking for me
Since vSphere doesn’t maintain any historical data with the guests themselves, we have to fall back on the Tasks and Events to create such a report. The basic algorithm to query the tasks, and their related events, is already published in Events – Part 3 : Auditing VM device changes. But to get a historical record of the servers where your guests have been hosted requires a bit more logic in the script.
