VMware View 5: End User Performance Monitoring

Over the next couple days I hope to bring some of new things of VMware View 5 that might get missed from the Hoopla that is VMworld.

VMware has added WMI based counters that capture what is going on PCoIP stream, the counters breakdown into 5 categories:

  • Audio
  • General
  • Imaging
  • Netowrk
  • USB







Companines like like Lakeside Software, SPLUNK, and Liqudware Labs are all integrating these into their products. VMware vCenter Operations is also said to be adding the type of monitoring to there overall solution.

ProfileUnity – New Release 4.8.1

Liquidware Labs new release of ProfileUnity 4.8.1 has three main points that I would like to cover.

1) – I had written a blog post about using ActiveSetup to speed up non-persistent machines. With 4.8.1 is it is now intregrated as a portablilty settings. Every easy to use and get up and running.

2) Log on Speeds – They have improved the movment of user persona data by changing giving two options to move data. For those unformilar with ProfileUnity, Liquidware Labs uses 7zip to compress and decompress the portabablity settings when logging off and on. The faster log on speeds results in bigger files being saved but it is less than 50% of the original.

3) Wizard Driven – If you just starting out you have the ability to use a wizard to configure your base policy instead of manually entering all the fields. It’s also nice now that unused settings are greyed out so you don’t have to go hunting around if you’re doing some troubleshooting.


Tip 41: Treat Your VDI Like A Produce Isle

You should also keep your VDI environment clean by refreshing or recomposing your desktops. If you’re using view composer and linked clones your virtual desktops won’t take up much space and you can redirect your IO to tiered storage. Sounds great right?

I think most people know that recomposing or refreshing will reclaim any space savings that you may have lost with the daily growth of the linked clones. I don’t want to spend too much time on the linked clone architecture since you can get all that information here: �

What I do want to point out is that all the writes are misaligned. After meeting our NetApp rep we got talking about the server side of the house and misalignment. This is what he had to say:

“The problem is the Delta disks use a grain size of 512 bytes. That means we don’t know by how much they will be misaligned, plus it could changed based on the IO the VM is doing. At this point there is no way to avoid the delta misalignment. All you can is mange it”

This was news to me and I thought I would pass it along to the masses.
