We do not monitor Access Switch Interfaces; other than uplinks to our distribution boxes. Any new alert gets just me in the email line until the alert is fine tuned. Some alerts are for devices that other departments use and they are plugged into the network so just they and me of course will get the alert. Network related alerts go to a lot of people, all the way up (they like to know). But remedial items; like UPS batteries and some redundant hardware items go to the Operations team to be handled. We use the heck out of UnDP's for status.
Implementation of trap and syslog alerts has been ramped up to cover all ends of a situation. At the same time; triggers in the syslog highlight specific events on nodes that trigger alerts to just me and a few folks. Sometimes a really granular syslog or trap alert helps me to maintain the 'Big Brother' status and keeps people looking over their shoulder.
