Custom updates to vCenter via VMTools

Already VMTools updates important information to vCenter via VMTools such as the operating system.

Is there a way to have it update other information that may be important in my settings?

For example I have a custom field in vCenter for versions of a particular app. I also have a script that reports the version of the app running. I would like to have VMTools populate that information to vCenter so that it is always up to date. As of now there is now guarantee that the app owners update vCenter when they update the App.

I understand that I could have an application update it directly to the SQL database, but my servers have no connections through the firewall to the SQL Database. This is by design and will not be changed.

Thanks.

I don't know that you will be able to do that directly with VMware Tools. However you could leverage the VMware vSphere Web Services SDK 4.1 (http://www.vmware.com/support/developer/vc-sdk/visdk41pubs/ApiReference/index.html) in a custom program to do what you wish. You would have to leverage the Windows task scheduler or Linux cron facility to make it run every so often to update whatever it is you are updating.

Tale a look under Data Object Types, the object type would be VirtualMachineConfigInfo, in that schema there is a extraConfig entry that takes Option/Value pairs, where you can specify key and value to update on the vCenter server. Here is the link for that structure: http://www.vmware.com/support/developer/vc-sdk/visdk41pubs/ApiReference/vim.option.OptionValue.html

Good Luck
