cpqarray

I've been playing around with the get-stat command. Thanks a bunch to Brian Denicola at http://www.bjd145.org/labels/vmware%20powershell.html for posting the example.

To grab memory stats from an ESX host type the command get-stat $esx -Memory -maxsamples 3 -realtime this will grab 3 memory samples from the server $esx.

For example

$vc = get-viserver myvcserver -username admin -password vmware
$esx = get-vmhost MyEsxServer
$get-stat $esx -Memory -maxsamples 3 -realtime

The -common switch gives averages for all major hardware subsystems cpu,memory, disk, and networking.

$get-stat $esx -common -maxsamples 1 -realtime

There is also a way to pull individual counters provided that you know the counter name

get-stat $esx -stat cpu.usagemhz.average

This returns the average cpu usage in MHZ over the interval of collection. The list of all counters can be found here:

If you're not reading the forum for the VMware VI Toolkit Beta you are missing out on just a goldmine of useful information. Take this post from LUCD. This will allow you to query the ESX host for it's current time. This another one of those instances where there is no applet in the toolkit to do this so you hook into the API to get the information.

$svcRef.Type = "ServiceInstance"

$svcRef.Value = "ServiceInstance"

$serviceInstance = get-view $svcRef

$datetime = $serviceInstance.ServerClock
