I need to install SHA ,i have followed these steps:
a. Log in to BSM as an administrator and go to Admin , Platform , Setup and Maintenance , License Management .
b. Select Service Health Analyzer , click the plus sign, and add a Service Health Analyzer license by navigating to and selecting the Service Health Analyzer license file.
So what? What are you asking about? Where to get a license file?
In the same place where you got other BSM license files.
