Enterprise Specific Trap (.9001) Uptime: x days, [Time], .iso.3.6.1.2.1.1.5.0 = STRING: “[Server Name]”, .iso.3.6.1.4.1.232.11.2.11.1 = INTEGER: 0

This SNMP trap was being triggered every now and again. Like many SNMP messages, there’s not always anything useful within them to help explain what actually happened.
Here’s an example:
Description: [IP Address]: Enterprise Specific Trap (.9001) Uptime: x days, [Time], .iso.3.6.1.2.1.1.5.0 = STRING: “[Server Name]”, .iso.3.6.1.4.1.232.11.2.11.1 = INTEGER: 0

In my case, a scheduled reboot caused the iLO on an HP BL460c Blade to trigger the SNMP alarm, which HP call “Server Reset Detected”.
