SNMP Traps Collector
SNMP Traps Collector will:
- Wait on the
/opt/opsview/snmptraps/var/run/snmpFIFO and once a trap is received, it reads it and processes it via the traps processing library available withopsview-snmptraps-base. - Process a trap by either sending a result to the results forwarder FIFO, or send an exception to the
snmp-traps-exception-queue. - Manage the starting and stopping of traces set on a host, running the trace for the given duration in minutes or hours (up to a maximum of 48 hours).
- Read messages from the
snmptrace-request-<machine-ref>queue and sends messages to theorchestrator-queueandsnmp-traps-exception-queue.
Dependencies Copied
- The package requires
opsview-datastoreto be installed on the collector so that it can create trace documents. - The package requires access to the
opsview-messagequeueto send traces and exceptions to theresult-snmp. - The package requires access to the
opsview-messagequeueto receive trace request message from the orchestrator.
Installation Copied
This is deployed when installing Opsview Monitor.
See MIBs for SNMP Traps and Gets to add MIBs that are required for translating SNMP Traps.

$ sudo /opt/opsview/watchdog/bin/opsview-monit <start|stop|restart> opsview-snmptrapscollector
The component logs to syslog like all other components. Note that you may see errors in syslog regarding No such file or directory: "/opt/opsview/snmptrapscollector/var/conf/snmptraps.cfg" until the first SNMP Trap rule is associated with a host and Apply Changes is performed.
