zabbix not receiving traps to /tmp/zabbix_traps.tmp

[gurlinks]

Hi, I'm trying to configure Zabbix to receive traps. I see snmptrapd port receiving traps. but, not writing to /tmp/zabbix_traps.tmp

I have followed the below procedure

1. Installed net-snmp-utils net-snmp-perl net-snmp

2. snmpd and snmptrapd service is running

3. cp ./zabbix-4.4.6/misc/snmptrap/zabbix_trap_receiver.pl /usr/bin

4. chmod +x /usr/bin/zabbix_trap_receiver.pl

5. added below lines to snmptrapd.conf authCommunity execute public perl do "/usr/bin/zabbix_trap_receiver.pl";

6. vi /etc/zabbix/zabbix_server.conf StartSNMPTrapper=1 SNMPTrapperFile=/tmp/zabbix_traps.tmp (same as zabbix_trap_receiver.pl)

7. restarted Zabbix server and snmptrapd.

when I send traps I can see it server receiving through tcpdump but not in zabbix_traps.tmp file

Are you running zabbix-server on a system that uses systemd? If so, is systemd's PrivateTmp setting causing the "/tmp" directory to be relocated to a private spot for zabbix-server?
