HP System Management Homepage Timeout Error

leave a comment »

From time to time, I get the following error when trying to load the HP System Management Homepage:

A timeout occurred when while loading data for the HP System Management Homepage which may result in missing or incomplete information. See the HP System Management Homepage log for additional information

How to solve this?
This is normally caused by bad SNMP settings, Community Strings and/or Version Control Agent on the problem host, make sure it is pointing to a valid version control repository manager.

Here are some samples….
