Error trying to use system.run in an Item

[adminjerry]

I am creating an Item for Linux servers where I want to run a command but keep getting the error "failed to configure logger".
Item parameters:
Zabbix agent
Key: system.run[ksplice kernel uname -r]
I have also tried this as system.run["ksplice kernel uname -r"] and also created a script with a line ksplice kernel uname -r and set permissions as 755.
Type of information: Text
Preprocessing: Discard with heartbeat.

My test server has these entries in zabbix_agent2.conf:
AllowKey=system.run[*,*]
Plugins.SystemRun.LogRemoteCommands=1

I have tested it in the item screen and also from command line zabbix_get -s IP -k system.run["ksplice kernel uname -r"]
Result every time: Error: failed to configure the logger
I can't figure out why this isn't working.

I suspect that is the error that your ksplice command returns...
from this page https://www.dbi-services.com/blog/al7/ I suspect you just have no permissions to run that command as user zabbix.

[opc@al ~]$ ksplice -y all upgrade
Error: failed to configure the logger
[opc@al ~]$ sudo ksplice -y all upgrade
Updating on-disk packages for new processes

You see, first it fails as ordinary user, and then runs via sudo...
