An SNMP Trap monitor checks messages received (or trapped) from devices. Traps are the logical equivalent to an alert from the vendor's perspective, so they are important to consider when designing your own monitoring policies or considering how to customize your own monitors.
What You Can Do
You can:
- Find out when a network device detects potential intrusions.
- Be notified when a redundant Internet connection has been enabled.
