We would like to change the dashboard refresh rate from 60 seconds to 5 minutes, but the documentation only references the following:
"You can turn auto refresh on and off using the option in the upper-right corner of the Performance Center user interface. Enabling auto refresh displays the most recent data. Auto refresh defaults to refresh every 60 seconds. However, this setting is adjustable. For example, if polling is set to 5 minutes, you can work with CA Support to set auto refresh to 5 minutes."
Release : 3.x
Component : IM Reporting / Admin / Configuration
To alter the refresh rate globally you would need to
1. Access this page and authenticate as the admin user:
Note: Use https:// and :8182 instead if using SSL.
2. Once there you need to find this parameter
3. Change the 60 to 300 then scroll to the top and click update.
