Traps v Events

Question

Hi guys,

Can anyone advise the difference between traps and events in Orion NPM? How does Orion generate / receive the events? My understanding is that traps will be generated by the network node itself, but I am unsure of how the event is generated. I assume that events are generated by polling the managed device?

Hi,

A SNMP Trap is sent by a network equipment to the Network Monitoring Solution. Orion provides a way to collect/manage these Packets throught the SolarWinds SNMP Service and the Trap viewer.

An Orion NPM event is an entry in the internal log of the application. Events are mostly created when Orion NPM detects a change in the network status/topology. Advanced alerts can log NPM events as well.

Here is a list of the event types:

Node Down
Node Warning
Node Up
Node Removed
Node Added
Interface Down
Interface Up
Interface Shutdown
Interface Unknown
Node Rebooted
Critical System Error
Interface Added
Interface Removed
Interface Remapped
Interface Changed
Monitoring Started
Monitoring Stopped
Interface Enabled
Interface Disappeared
Interface Reappeared
Fail Over
Fail Back
Application Stopped
Application Restart
UnManage Node
Manage Node
Node Changed
Volume Remapped
Volume Changed
Volume Added
Volume Removed
Volume Disappeared
Volume Reappeared

Informational
Warning
Critical
Alert Triggered
Alert Reset

Orion modules add further event types when you install them.

HTH,

Yann
