Chapter 3 CLI Commands
show alarms
• Node Health Manager (alarm overload condition)
• System Monitor (sysmon) for disk failures
The three levels of alarms in the WAAS software are as follows:
• Critical—Alarms that affect the existing traffic through the WAE and are considered fatal (the WAE
cannot recover and continue to process traffic).
• Major—Alarms that indicate a major service (for example, the cache service) has been damaged or
lost. Urgent action is necessary to restore this service. However, other node components are fully
functional and the existing service should be minimally impacted.
• Minor—Alarms that indicate that a condition that will not affect a service has occurred, but that
corrective action is required to prevent a serious fault from occurring.
You can configure alarms using the snmp-server enable traps alarms global configuration command.
Use the show alarms critical EXEC command to display the current critical alarms being generated by
WAAS software applications. Use the show alarms critical detail EXEC command to display additional
details for each of the critical alarms being generated. Use the show alarms critical detail support
EXEC command to display an explanation about the condition that triggered the alarm and how you can
find out the cause of the problem. Similarly, you can use the show alarms major and show alarms
minor EXEC commands to display the details of major and minor alarms.
Use the show alarms history EXEC command to display a history of alarms that have been raised and
cleared by the WAAS software on the WAAS device since the last software reload. The WAAS software
retains the last 100 alarm raise and clear events only.
Use the show alarms status EXEC command to display the status of current alarms and the alarm
overload status of the WAAS device and alarm overload configuration.
Examples Table 3-3 describes the fields shown in the show alarms history command display.
Table 3-4 describes the fields shown in the show alarms status command display.
