The SNMPTT translator is required to collect information received via SNMP traps.
To process SNMP traps with the SNMPTT service, the SNMP trap OID contained in the MIB file must be converted into a file with the .conf extension.
The utility snmpttconvertmib is used here, which is included in the /etc/snmp/snmptt.ini file.
In the Nagios configuration file, you must add a passive query template and associate this pattern with a group of hosts, for example.
Note:
The name "Trap1" must match the name of the SNMP trap notification in the Didactum Monitoring System.
SNMP Traps under Nagios:
Nagios uses passive notifications and checks in the form of SNMP traps. For example, the Didactum IT monitoring system uses this method to report when events occur.
To receive and interpret SNMP traps, the following tools are required:
- Net-SNMP snmptrapd SNMP Trap Services (http://www.net-snmp.org/)
- SNMPTT - SNMP Trap Handler (http://snmptt.sourceforge.net/)
The Net-SNMP snmptrapd utility is configured as follows:
Notes:
The following packages/plugins are required for integrating Didactum monitoring systems and their associated intelligent IP sensors:
- check_didactum-pl - Didactum Sensor Plugin
- check_didactum_table.pl - Plugin for checking SNMP sensors
- submit_check_result - Script for passively checking SNMP traps
These plugins can be found in the DidactumNagios.zip file in our download area at www.didactum-security.com/didactum-downloads/firmware.html
Additionally, the following are required:
- Net-SNMP - Collection of SNMP tools
- pnp4nagios - Nagios add-on for creating graphs and charts
- SNMPTT - SNMP Trap Handler for Nagios
