Utilizing script option in policy/rule-based actions to produce custom alert.

Hello.

I am using DPA V6.2.1 installed on a windows server (not ideal). I am trying to customize an alert for a Avamar job failure. We're using DPA policy to currently generate our alerts with the email option. Unfortunately the basic format from the email output is not satisfying our needs. I thought I could utilize the option to execute a script and perform text processing in that script with the parameter variables found on page 183 of the Installation and Administration guide.

First of all, I couldn't find documentation on how DPA executes the script, or even what is an acceptable scripting language.

I wrote a test script in PowerShell. It does generically what I want it to do and I have tested it successfully. It also emails me whenever the script is executed. Following the Installation and Admin guide, I've put the script, AvamarAlert.ps1 in the directory /services/shared/AvamarAlerts/AvamarAlert.ps1. I have set this path in the Analysis policy and set it to run on successful backups (I also configured email out to know that the alert generated successfully). DPA is not executing the script. I've looked in the application logs to see if there was anything, but nothing useful.

So I guess my questions are thus:

1. What is the acceptable scripting languages that DPA can call (i.e. batch, VB, PS, BASH)?

2. How does it call it? (i.e. using the sytem account, or a different service account?)

Those are the issues for now, hopefully the parameters work correctly like they are listed in the documentation.
Thanks!
