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.

To setup a WSUS server on a workgroup server, you need to alter the register.
You can find the register keys here: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WindowsUpdate
AU register settings are in the key: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WindowsUpdate\AU
For more information on keys you can follow the next link: http://technet.microsoft.com/en-us/library/cc708449(WS.10).aspx
With the command “wuauclt.exe /detectnow” you can let the WSUS server detect your machine faster.
Send the queued information directly to the wsus server with: “wuauclt /r /reportnow”
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
How to create a bootable USB key from which you can install Windows 7 on your system.
Now you have a USB key with an installable windows 7 on it. It will install faster then a DVD and it’s easier to carry it with you. Another advantage is that you can install netbooks without dvd players from the USB key.
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.
