rising or falling threshold crossing event indicator, the sample type (absolute or delta), the sampled value,
the threshold value, the rmon-alarm-id, the associated rmon-event-id, and the sampled SNMP object
identifier.
The alarm command configures an entry in the RMON-MIB alarm table. The alarm command controls the
monitoring and triggering of threshold crossing events. To trigger the notification or logging of a threshold
crossing event, at least one associated rmon event must be configured.
The agent periodically takes statistical sample values from the MIB variable specified for monitoring and
compares them to thresholds that have been configured with the alarm command. The alarm command
configures the MIB variable to be monitored, the polling period (interval), sampling type (absolute or
delta value), and rising and falling threshold parameters. If a sample has crossed a threshold value, the
associated event is generated.
Preconfigured CLI threshold commands are available. Preconfigured commands hide some of the
complexities of configuring RMON alarm and event commands and perform the same function. In
particular, the preconfigured commands do not require the user to know the SNMP object identifier to be
sampled. The preconfigured threshold configurations include memory warnings, alarms, and compact flash
usage warnings and alarms.
To create events, use the following sample CLI configuration.
Example
config>system>thresholds# cflash-cap-warn cf1-B: rising-threshold 2000000 falling-threshold
1999900 interval 240 trap startup-alarm either
Example
config>system>thresholds# memory-use-alarm rising-threshold 50000000 falling-threshold 45999999
interval 500 both startup-alarm either
Example
config>system>thresh# rmon
Example
config>system>thresh>rmon# event 5 both description "alarm testing" owner "Timos CLI"
