Configuring passive thresholds

Alert Center passive thresholds notify you when WhatsUp Gold passive monitors fall out of the parameters of the thresholds you configure. You can create three passive threshold types:

• SNMP trap
• Syslog
• Windows Event Log

Several things to keep in mind when configuring thresholds for passive monitors:

• For a passive threshold to work, the passive monitor for which you are creating a threshold must be assigned to and collecting traps from at least one device.
• For each type of passive threshold, the list of available monitors for which you can create a threshold is populated with monitors currently configured for use in the Passive Monitor Library. However, the monitors in this list are not necessarily assigned to any devices. You can create a dynamic group to find the devices to which a particular passive monitor is assigned to see if that particular monitor warrants an Alert Center threshold. For more information, see Dynamic Group Examples.
• There is no mechanism in the Alert Center to monitor unsolicited traps.
