What is eventSystem?

This OCTET STRING reports the computername of the host that generated the underlying Windows event. Because evntagent traps are forwarded from individual Windows machines, this field lets an NMS receiving the trap identify which server or workstation raised it, independent of the trap's source IP. For instance, a w32SystemStartup trap might carry the value "FILESRV02", telling the admin exactly which machine just rebooted.
