zabbix_get on proxy and zabbix_agentd on client reports different

[royalliege]

Hello,

I have written a python script to monitor allocation on vgdocker and added it as an item to Zabbix. Although I get the right value with zabbix_agentd on client server(dockerserver); zabbix_get on proxy server generates error:


I ran the command with zabbix user (su -s /bin/bash zabbix)
$ zabbix_agentd -t vg.allocated.pool[Allocated]
vg.allocated.pool[Allocated] [t|25.36]
$ zabbix_agentd -V
zabbix_agentd (daemon) (Zabbix) 4.0.3

Could you assist me what to check?

Thanks,


Edit: Solved by changing sudo permission to run the whole script rather than vgdisplay command.
