must be updated
1. "2 Setting up SNMP trap monitoring" document section
When SNMPTT is configured to receive the traps, configure SNMPTT to log the traps:
log traps to the trap file which will be read by Zabbix:
log_enable = 1
log_file = [TRAP FILE]
set the date-time format:
date_time_format = %H:%M:%S %Y/%m/%d = [DATE TIME FORMAT]
needs the following:
net_snmp_perl_enable = 1
2. "4 Setup example" document section
snmptt.ini - configure output file and time format: log_file = /tmp/my_zabbix_traps.tmp date_time_format = %H:%M:%S %Y/%m/%d
needs the following:
net_snmp_perl_enable = 1
Without this the example setup does not work (for Zabbix 4.5 on Ubuntu).
Interestingly, the community setup guide for the CentOS does mention this config:
https://zabbix.org/wiki/ConfigureSnmptrapsCentos6_RHEL6
Edit snmptt Config vi /etc/snmp/snmptt.ini translate_log_trap_oid = 2 net_snmp_perl_enable = 1 date_time_format = %H:%M:%S %Y/%m/%d log_file = /tmp/zabbix_traps.tmp log_system_enable = 1
