SNMP Monitoring
For system analysis and monitoring purposes, the Gateway acts as a SNMP (Simple Network Management Protocol) Agent in an SNMP-enabled network.

WARNING!
SNMP support is an optional Gateway configuration with inherent security implications. The procedures required to configure the Gateway as a SNMP Agent are dependent on site and network factors and must be implemented in consultation with a CA Technologies Professional Services Specialist.For system analysis and monitoring purposes, the Gateway acts as a SNMP (Simple Network Management Protocol) Agent in an SNMP-enabled network.
Using an existing tool like SNMPWALK from the Net-SNMP tool kit (http://net-snmp.sourceforge.net) configured with the MIB (Management Information Base) information in Gateway as SNMP Agent, you can construct the following:
- various "SNMP GET" queries
- requests for Gateway CPU load
- network traffic
- other basic statistical information.
When queried, the Gateway returns an SNMP trap notification with the required counter data. Since the SNMP query and response processes are executed independently from the standard Gateway functionality, they do not affect the performance of the implementation.
The configured threshold of the Gateway’s Audit Log determines the type and depth of audit records that are accessible by the SNMP queries.
Related to but separate from the Gateway’s SNMP Agent functionality, you can configure a Send SNMP Trap Assertion in the Policy Manager. When encountered in a policy path, the Send SNMP Trap Assertion instructs the Gateway to broadcast an SNMP trap event to a predefined network address. The event could be an alert based on the processing result of a previous assertion, or an alert based on another policy processing outcome.
