Unstable indicates that a system has repeatedly restarted over a short period of time and is considered unstable. The RestartTrapThreshold and the RestartTrapWindow parameters in the Connectivity setting for the “System Resources Groups” threshold group control the analysis for a system unstable condition. The VMware Smart Assurance IP Management Suite Configuration Guide provides information about these parameters.
“Diagnosis of Unstable Objects” on page 129 provides information about how IP Availability Manager concludes that a system is unstable.
The event used as a symptom to diagnose a system Unstable problem is SNMPAgent RepeatedRestarts.
