Truenas Scale - Zabbix App Problems Fping/ICMP

[Llanelwy]

Hi,

I have just installed the Docker App for Zabbix on my Trunas Scale Homeserver. But i am running into some problems. All ICMP monitoring seems to fail. SNMP works fine however.

I have had a poke about and went into the Shell for the Zabbix app. From the command line Ping works fine. However fping always shows Host Unreachable. Even when trying localhost.

$ bash
zabbix@f501d68535a1:~$ ls
dbscripts enc enc_internal export mibs modules snmptraps ssh_keys ssl
zabbix@f501d68535a1:~$ ping localhost
PING localhost (::1) 56 data bytes
64 bytes from localhost (::1): icmp_seq=1 ttl=64 time=0.035 ms
64 bytes from localhost (::1): icmp_seq=2 ttl=64 time=0.047 ms
64 bytes from localhost (::1): icmp_seq=3 ttl=64 time=0.049 ms
^C

3 packets transmitted, 3 received, 0% packet loss, time 2004ms

zabbix@f501d68535a1:~$ fping localhost
localhost is unreachable
zabbix@f501d68535a1:~$

I am sure this is a simple config error on my part, but I can't seem to find it. I have looked at the fping location in the zabbix_server config files. The only mention I can find is in zabbix_server_location.config Which i appear unable to edit or modify as there appears to be no editor in the docker container at all (vi, vim nano all appear to not be installed)

### Option: FpingLocation
# Location of fping.
# Make sure that fping binary has root ownership and SUID flag set.
#
# Mandatory: no
# Default:
# FpingLocation=/usr/sbin/fping

FpingLocation=${ZBX_FPINGLOCATION}

### Option: Fping6Location
# Location of fping6.
# Make sure that fping6 binary has root ownership and SUID flag set.
# Make empty if your fping utility is capable to process IPv6 addresses.
#
# Mandatory: no
# Default:
# Fping6Location=/usr/sbin/fping6

Fping6Location=

Hope this is a quick fix and something i am just missing in the zabbix config somewhere. Thanks
