I wanted to set an alert if tomcat heap memory usage exceeds 75% of meximum, but I got an alert even for lower values (this is copy/paste from alert e-mail):

Conditions: 
  - Condition 1: Heap Usage > 75,0% of Baseline Maximum Value
  - Date/Time: 2012/02/01 10:55:11 CET
  - Details: 92,9MB

This tomcat has 1GB+ memory assigned. Did I used wrong condition?

Thank you in advance,
Milan
