Chapter 1
Thresholding Overview
Thresholding on the system is used to monitor the system for conditions that could potentially cause errors or outage.
Typically, these conditions are temporary (i.e. high CPU utilization, or packet collisions on a network) and are quickly
resolved. However, continuous or large numbers of these error conditions within a specific time interval may be
indicative of larger, more severe issues. The purpose of thresholding is to help identify potentially severe conditions so
that immediate action can be taken to minimize and/or avoid system downtime.
The following thresholding models are supported by the system:
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.
In the example shown in the figure below, this model generates alerts during period 2, 3, and 5 at the point
where the count exceeded HT.
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.
The alarm is cleared at the end of the first interval where the measured value is below the low threshold.
In the example shown in in the figure below, this model generates an alarm during period 2 when the count
exceeds HT. A second alarm is generated in period 6 when the count falls beneath LT. The second alarm
indicates a “clear” condition.

OL-25552-02
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.

AAA:
Archive size
Number of authentication failures
Authentication failure rate
Number of accounting failures
Accounting failure rate
Retry rate

Thresholding reports conditions using one of the following mechanisms:
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.
The generation of specific traps can be enabled or disabled on the system allowing you to view only those traps
that are most important to you.

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.
“Outstanding” alarms are reported to through the system’s alarm subsystem and are viewable through the
system’s CLI.

Saving Your Configuration
When you configure thresholds they are not permanent unless you save the changes. When you have completed
configuring thresholds, save your configuration to flash memory, an external memory device, and/or a network location
using the Exec mode command save configuration. For additional information on how to verify and save
configuration files, refer to the System Administration Guide and the Command Line Interface Reference.
