Identifying Hardware and OS Threshold Breaches

If the value of a monitored hardware health attribute, or OS resource utilization attribute breaches a threshold value, an event log is immediately created, which indicates that the threshold has been breached. The event log is available from the browser interface. A symbol appears among the monitored data table in the browser interface to indicate that a threshold has been breached, as shown in the graphic at To Retrieve Threshold Values for a Server in Sun N1 System Manager 1.3 Discovery and Administration Guide.

Alternatively, use the show log command to verify that the event log has been generated:

A critical high threshold was violated for server Sun_V20z_XG041105786: Attribute cpu0.vtt-s3 Value 1.32

A normal low  threshold was violated for server Sun_V20z_XG041105786: Attribute cpu0.vtt-s3 Value 1.2

If monitoring traps are lost, a particular threshold status may not be refreshed for up to 30 hours, although the overall status can still be refreshed every 10 minutes.
