Hello guys,

I have something very strange with custom script.
Zabbix server - 3.2.7
client Debian 9 - 3.0.7

Running the script in the client working fine:

./rancher.sh stats Traefik-nginx-1 .cpu.usage.user
215940000000

Running the script from zabbix_agent_d working fine :

zabbix_agentd -t rancher[stats,Traefik-nginx-1,.cpu.usage.user]
rancher[stats,Traefik-nginx-1,.cpu.usage.user] [t|215950000000]

Running from the server returned empty string

zabbix_get -s 172.30.101.12 -k rancher[stats,Traefik-nginx-1,.memory.usage]

The script works perfectly with other argument

root@5e2b6f34a9b3 /]# zabbix_get -s 172.30.101.12 -k rancher[discovery,hosts]
{
"data" :
[
{"{#ID}":"1h60","{#NAME}":"infra-l1.labs.napalmlabs.fr"},{"{#ID}":"1h65","{#NAME}": "ross-galdo.labs.napalmlabs.fr"},{"{#ID}":"1h66","{#NAME }":"heidi-benesch.labs.napalmlabs.fr"},{"{#ID}":"1h68","{#NA ME}":"beth-lourence.labs.napalmlabs.fr"},{"{#ID}":"1h69","{#N AME}":"infra-l2.labs.napalmlabs.fr"}
]
}

At the end of the script, if I return fixed value (like echo 1) it's working.
