Vmware Horizon View Protocol Failure

Posted on  by

So two weeks ago I had a nice little post about talking to Horizon View using PowerCLI. I also promised to be digging a bit more into PowerCLI by grabbing the script posted on the VMware blog and editing it a little to my taste. It’s a very useful script they have on there but still I prefer to know what might have caused the issues. I'm unsure which version of Horizon we're running in our environment. I will reach out to the team responsible for more info. I'm running version 4.8.1 of the Horizon Client, but I will upgrade to 4.9.0 and see if that corrects the issue. Update: Using v4.9.0 did not correct the issue. The vPC has been rebooted. Oct 21, 2013 Resolving the Blast Protocol Failure Issue with Horizon View 5.2. One of the new features packaged with VMware Horizon View 5.2 is the ability to provide desktop access by way of the Blast protocol with HTML5. This gives you three major methods to connect users to their desktops: PCoIP, RDP, and Blast. Horizon View HTML Access is required to be.

In addition, the document provides information on how to implement and troubleshoot each graphics technology.

Update: There is a new way to pull the event information without having to enter the sql password please see this post about it.

So two weeks ago I had a nice little post about talking to Horizon View using PowerCLI. I also promised to be digging a bit more into PowerCLI by grabbing the script posted on the VMware blog and editing it a little to my taste. It’s a very useful script they have on there but still I prefer to know what might have caused the issues. I decided I needed to know who the last user was that used the desktop and the last entry into the eventlog and the time of that log. So actually most code used talks to the eventlog database, something already available pre PowerCLI 6.5 but what I hardly ever used.

The basics for connecting I won’t post but we do need an extra connection and that is to the event database:

As with the Horizon View connection it’s best to put this into a variable so it can be used later on. The $hvedbpassword should be the password for the user that View uses to connect to the database server in plain text! Earlier in the script I read the password from hashed contents in a text file.The request has been dropped to be able to pass encrypted credentials and/or creta a credentialstore for this.

Next up is grabbing the events for a certain Desktop

This could use some rework since I would prefer the time period to be a variable based on the current date but if the event is older then a day it will be hard to find anything on it anyway.

This grabs the latest event, the time it happened and the user it happened to. This can be anything including a logoff. It might be able to help you why a lot of desktops are ending up in a rotten state.

The rest of the script is basic building of arrays, filling them, mailing it etc etc. So still not a lot of complicated code that some people build but it’s a bit of the basics in talking to the View Api and the event database.
