If I place a device in maintenance mode or the device enters a maintenance schedule, will WhatsUp Gold still collect Passive Monitor data from the device?
In a word, yes. The maintenance mode feature prevents polling of Active Monitors and Performance Monitors from occurring, but it will not prevent incoming Windows Events, Syslog messages, or SNMP Traps from being received and processed by WhatsUp Gold. Any actions assigned to these Passive Monitors will be triggered even if an event is received while the device is in maintenance mode.
