• Alert: A value is monitored and an alert condition occurs when the value reaches or exceeds the configured high threshold within the specified polling interval. The alert is then generated and/or sent at the end of the polling interval.
• Alarm: Both high and low thresholds are defined for a value. An alarm condition occurs when the value reaches or exceeds the configured high threshold within the specified polling interval. The alert is then generated and/or sent at the end of the polling interval.Important: Note that for certain values, the alert or alarm serves to warn of low quantities (i.e. memory, session licenses, etc.). In these cases, the low threshold is the condition that must be met or exceeded within the polling interval to generate the alert or alarm. Once the high threshold is exceeded during an interval, the low quantity condition is cleared.

• SNMP traps: SNMP traps have been created that indicate the condition (high threshold crossing and/or clear) of each of the monitored values. Complete descriptions and other information pertaining to these traps is located in the starentMIB(8164).starentTraps(2) section of the SNMP MIB Reference.
• Logs: The system provides a facility called threshold for which active and event logs can be generated. As with other system facilities, logs are generated Log messages pertaining to the condition of a monitored value are generated with a severity level of WARNING.Refer to the System Administration Guide for additional information on system logging functionality.
• Alarm System: High threshold alarms generated within the specified polling interval are considered “outstanding” until a the condition no longer exists and/or a condition clear alarm is generated.
