The SNMP channel allows the logging server to send filtered events to an SNMP management system.
A decoded SNMP trap appears as follows:
The trap values are as follows:
SNMP Version |
The traps SNMP version. The Nsure Audit SNMP driver sends SNMPv1 traps. |
Community |
The string, or password, needed to access the SNMP management system. |
Command |
The SNMP Command. This is always Trap. |
Enterprise |
The Enterprise that sent the event is always 2.16.840.1.113719.1.347.3.1 . |
Network address |
The IP address of the logging server that sent the trap. |
Generic trap |
The Generic Trap field is always 6 (Enterprise specific). |
Specific trap |
The Specific Trap field always contains the EventID of the event that triggered the trap. |
Time Ticks |
Time Ticks is always the time the event was sent in seconds since 1970. |
Object |
The Object of the trap is the Object ID specified in the SNMP Channel object. If no Object ID is specified in the SNMP Channel object configuration, the Nsure Audit internal OID is used (2.16.840.1.113719.1.347.3.1). |
Value |
The Value associated with the Object is the message configured in the SNMP Channel object. |
At startup, the SNMP driver, lgdsnmp.*, performs a server check; that is, the driver attempts to connect to the designated host at UDP port 162. The server check verifies the driver can actually communicate with the server before it attempts to send SNMP traps. If the server check fails, the SNMP driver refuses to load. This safeguard ensures that no traps are lost due to misconfiguration.
NOTE: The SNMP driver does not buffer traps that are undeliverable due to misconfiguration or a server failure.
The SNMP driver sends SNMPv1 traps.
