In the past I have written about two of TripWire’s free tools - OpsCheck and ConfigCheck.

(see How can the free vWire OpsCheck help with your VMotion Configuration?
and Assessing VMware ESX server security with TripWire ConfigCheck)

Now, TripWire has launched a new, more complete management tool for your VMware environment called vWire.

Here’s what it can do for you:

• Monitors the health of your virtual infrastructure
• Correlates that data
• Alert you and take action
• Integrate with vCenter

Compared to other virtualization management tools, vWire is very inexpensive and there is  a free 30-day eval. Checkout vWire at this link
