Defining a Monitoring Request
Selecting Protocols for Sending Events
The Severity area options for SNMP traps are:
• Map from value (this is not available with all monitors)
• Critical
• Major
• Minor
• Warning
• Normal
A specified severity other than Normal is returned under the following
conditions:
• When value is . . . If this notification option is set, a non-normal
severity occurs when the value changes from FALSE to TRUE.
For example if a disk is being monitored, you want notification when
the disk is down. The When value is condition is FALSE while the
disk is up and running correctly. The condition becomes TRUE,
meaning action needs to be taken, when the disk is down or not
operating correctly.
• When value changes If this notification option is set, a non-normal
severity occurs when the current value does not match the previous
value
Certain SNMP monitoring requests can map directly to severity levels.
Select the Map from value option from the list in the Severity area.
