TrapCountThreshold runs as a Quartz job and can be seen via the controller (/SnmpManager/quartz/list) or as a config entry:

select * from snmp_manager.QRTZ_CLUSTER_TRIGGERS where JOB_NAME  = 'com.errigal.snmpmanager.jobs.TrapCountThresholdJob';

Setting up TrapCountThreshold for the following traps:

…

When the job runs, traps are queries with the below statement:

SELECT count(*) as trapCount, ne.id, gts.trap_name
FROM snmp_manager.general_trap_summary gts, snmp_manager.network_element ne
WHERE gts.trap_name LIKE ${TrapName}
AND gts.received_date > date_sub(now(), interval ${TrapCountThresholdIntervalInHours} hour)
AND gts.alarm_status= ${TrapSeverity}
AND gts.network_element_id = ne.id
GROUP BY ne.id, gts.trap_name;

Sample result list for VoltServer traps:

Sample TrapCountThreshold config:

For the functionality to kick-off, the returned trapCount from the first result set has to be greater than the configured trap_count_threshold in the trap_count_threshold configuration in the second result set.

The system will then send a Trap Breached Threshold alarm with parameters from the first result set.

Resulting GTS info based on the above configuration:
