To define your own handlers and change the EXEC statement to your needs or comment it out. Unknown traps will be logged to /var/log/snmptt/snmpttunknown.log. Also the file /root/testsuccessful should be created so our custom handler command was also fired.įrom this point on you should be able to create your own handlers. Now you should now have the logfile /var/log/snmptt/snmptt.log created and filled whith your entry.

We can give this all a try by entering the following command (best done from another machine to see it´s working from other hosts, change DESTINATIONIP to match yours): snmptrap - v 1 - c public DESTINATIONIP "" "" 1 1 "" Through the creation of an EventSource, LogicMonitor can alert on SNMP traps received by the Collector. Should show snmpd and snmptrapd are running. Overview SNMP traps involve the monitored device sending a message to a monitoring station (the LogicMonitor Collector in our case) to notify of an event that needs attention. To do so edit /etc/snmp/nf and paste the following lines at the end: #ĮVENT test. Now we will create a handler for a test trap. This enables logging all incoming traps to /var/log/snmptt/snmpttunknown.log. If you activate this check, any trap not being captured under a host will get thrown in the server logs. Next edit /etc/snmp/snmptt.ini and change unknown_trap_log_enable = 0 This might be too late but there is a setting under Adminstration/General/Other (depending on the version, the menu might change) mentionning 'Log unmatched SNMP traps'. With Net-SNMP release 5.3 and later, you must specify who is authorized to send traps and informs to the notification receiver (and what types of processing these are allowed to trigger). You configure how incoming traps process in the /etc/snmp/nf file. snmptrapd passes the trap to SNMPTT or calls Perl trap receiver. The workflow of receiving a trap: snmptrapd receives a trap. Here we are specifically interested in configuring the trap receiver. The Net-SNMP trap daemon in /etc/snmp/nf receives SNMP traps. Receiving SNMP traps in Zabbix is designed to work with snmptrapd and one of the built-in mechanisms for passing the traps to Zabbix - either a perl script or SNMPTT. This is needed for snmptt to recognize the incoming traps. formally known as UCD-SNMP, is installed by default on most Linux distributions.

The ‘-On’ parameter tells snmptrapd to log OID numbers. To TRAPDOPTS = '-On -Lsd -p /var/run/snmptrapd.pid'

You can define which incoming traps you want to process and where to log them to (syslog, File, Database).
