Passive Monitor Properties - Select Passive Monitor Type

Which passive monitor class would you like to add. Select a passive monitor class from the pull-down list.

SNMP Trap. A trap is an unsolicited SNMP message sent from a device to indicate a change in status, such as a router indicating one of its interfaces went down or a printer indicating that it is out of paper.
Syslog. A Syslog monitor is used to examine Syslog messages forwarded from other devices for a specific record and/or specific text within a record. Usually Syslog messages are forwarded from the "Syslog" on a system that runs UNIX, but they can also come from non-UNIX devices as well. They might contain anything that you want permanently logged, such as a device failure, or an attempt to log in to the system.
Windows Event Log. This could be monitoring when a service is started or stopped, if there was a logon failure, or any other entry in the Windows Event Log.
