Architectural Overview of NonStop SNMP
•
The SNMP agent uses Interprocess Communication (IPC) messages to 
communicate with independent subagents about the resources they manage. 
Subagents can reside on the same node as the SNMP agent or on different nodes. 
Each SNMP agent can support one instance of any particular subagent.
•
The SNMP control file (SNMPCTL) contains configuration parameters for the 
SNMP agent.
•
When the primary SNMP agent process is active, it writes trace records to the file 
ZZSMPTRP. When the backup process becomes active, it writes to the file 
ZZSMPTRB.
