During a converter action, the following error occured: “The session is not authenticated”.
After searching for a solution, i found two converter sessions on the server:
When killing all converter action, i could restart the session and do a succesfull convert action.
To correct the issue I removed the sysprepDecryptor.exe registry entry from the session manger key.
Here is the location to delete the sysprepDecryptor.exe registry entry.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\
Value name = BootExecute
Default Value = autocheck autochk *
vLogView is a Windows® based application which manages VMware® ESX Server log files.
The product is designed to be installed on an administrators PC, and provides the ability to store, view and search ESX Server log files from multiple ESX Servers, without requiring individual login, navigation and manual file transfer.

Thanks to the previous post (http://lucd.info/?p=1455) and a little extra scripting, i am able to run a script which will run daily scheduled and email the results to my mailbox.
This script will mail a CSV file with all cpu averages in 5 minutes samples between 7.30 and 19:30 off a specific Virtual machine.
If other counters are needed, you can find them in the following document: http://www.vmware.com/support/developer/vc-sdk/visdk25pubs/visdk25programmingguide.pdf
Beneath is the script i’m using (change all bold items):
Add-PSSnapin VMware.VimAutomation.Core
# Mail variables
$enablemail="yes"
$smtpServer = "smtpserver"
$mailfrom = "emailadres"
$mailto = "emailadres1,emailadres2"
# Server Variables
$VIServer = "viserver"
$vmName = "vmname"
# Log File Location
$log = "path\CPU_Stats" + "_" + $VMname+ ".csv"
# Connect to the VI Server
Connect-VIServer $VIServer
# Script
$esxImpl = Get-VM -Name $vmName
$todayMidnight = (Get-Date -Hour 0 -Minute 0 -Second 0).AddMinutes(-1)
$workingDays = "Monday","Tuesday","Wednesday","Thursday","Friday"
$dayStart = New-Object DateTime(1,1,1,7,30,0) # 07:30 AM
$dayEnd = New-Object DateTime(1,1,1,19,30,0) # 07:30 PM
$stats = Get-Stat -Entity $esxImpl -Stat cpu.usage.average -Start $todayMidnight.AddDays(-0) -Finish $todayMidnight.AddDays(+1)
$report = $stats | Where-Object {
$workingDays -contains $_.Timestamp.DayOfWeek -and
$_.Timestamp.TimeOfDay -gt $dayStart.TimeOfDay -and
$_.Timestamp.TimeOfDay -lt $dayEnd.TimeOfDay
}
$report | Export-Csv $log -NoTypeInformation
if ($enablemail -match "yes")
{
$msg = new-object Net.Mail.MailMessage
$att = new-object Net.Mail.Attachment($log)
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$msg.From = $mailfrom
$msg.To.Add($mailto)
$msg.Subject = “CPU Statistics $VMname”
$msg.Body = “Business-hours CPU Statistics are attached ”
$msg.Attachments.Add($att)
$smtp.Send($msg)
}
$VIServer | Disconnect-VIServer -Confirm:$false
To get the average cpu statistics from a virtual machine use the line below.
Get-Stat -Entity (Get-VM $VMName) -Stat cpu.usage.average -MaxSamples 5 -IntervalMins 5
This will give a cpu average off the last 25 minutes.
Other examples are on this webpage: http://lucd.info/?p=1383
An excellent article which explains a lot of counters from esxtop. With ESXtop you can see a lot of performance counters of your ESX server.
Check MTU settings on ESX 3.5:
esxcfg-vswitch -l

A nice oneline script to show the total VM’s on your datastore:
Get-Datastore | Select Name, @{N="NumVM";E={@($_ | Get-VM).Count}} | Sort Name
Example output:
| Name | NumVM |
| VMFS_0 | 5 |
| VMFS_1 | 2 |
