I once installed Zabbix Server 5.2 on Ubuntu Server 20.04 and noticed the following errors in /var/log/zabbix/zabbix_server.log:
item “192.168.5.5:icmppingloss” became not supported: fping failed: 192.168.5.5
item “192.168.5.5:icmppingsec” became not supported: fping failed: 192.168.5.5
item “192.168.5.5:icmpping” became not supported: fping failed: 192.168.5.5
The following path to fping was specified in the Zabbix server configuration /etc/zabbix/zabbix_server.conf:
FpingLocation=/usr/bin/fping
Fping6Location=/usr/bin/fping6
I tried fping manually, and I was convinced that it works:
/usr/bin/fping 192.168.5.5
192.168.5.5 is alive
Then I looked at fping and owner permissions:
ls -la /usr/bin/fping
-rwxr-xr-x 1 root root 52128 Feb 20 2019 /usr/bin/fping
The reason for the error turned out to be that zabbix could not access fping, and therefore I indicated the zabbix group to him:
chown root:zabbix /usr/bin/fping
chown root:zabbix /usr/bin/fping6
After that, the error was resolved.
