The Root cause Analysis (RCA) messages for any attribute will be changed whenever there is a change in severity. It will not change during every polling.
For example, let us assume that you have associated a threshold ( Critical > 90, Warning > 80 and Clear <= 80 ) to Cpu Utilization of a server. If the current cpu utilization value is 92%, then RCA message for Health of the monitor will say
| Quote: |
| Health is critical.Root Cause :
1. CPU Utilization 92 > 90 % (threshold). |
The RCA message for CPU Utilization attribute will say,
| Quote: |
| CPU Utilization - Critical.CPU Utilization of app-w2k1.india.adventnet.com is critical because its value 92 > 90 %.
[Threshold Details : Critical if value > 90, Warning if value > 80, Clear if value <= 80] |
In the next poll if the cpu utilization value increases to 96%, the RCA message will not be updated now for Health and CPU Utilization attribute. This message will be updated only when the cpu utilization becomes less than 90 ( when it becomes either warning or clear ). The RCA message for Health of the monitor will change however if another attribute becomes critical. So if the Physical Memory Utilization (%) also becomes critical, the RCA message for Health of the monitor will say,

| Health is critical.Root Cause :
1. Physical Memory Utilization 93 > 90 % (threshold). 2. CPU Utilization 92 > 90 % (threshold). |
