Open 2 terminals.
1 terminal: tail -f /var/log/zabbix/zabbix_agent2.log
1 terminal to change configs/restart agent2.
Make a config error, like:
Server=127.0.0.1;1.2.3.4
Increase debug level:
DebugLevel=5
Validate config:
zabbix_agent2 -T
and see (expected!):
Validating configuration file "/etc/zabbix/zabbix_agent2.conf" zabbix_agent2 [1920653]: ERROR: Cannot validate configuration: failed to validate "Server" configuration parameter: invalid "Server" configuration: incorrect address parameter: "127.0.0.1;1.2.3.4".
Good. Let's restart the agent:
systemctl restart zabbix-agent2
Observed result:
2025/05/06 22:01:02.000381 check 'log[/tmp/test.log]' is not supported: Cannot obtain information for file "/tmp/test.log": [2] No such file or directory 2025/05/06 22:01:05.001295 check 'log[/tmp/test.log]' is not supported: Cannot obtain information for file "/tmp/test.log": [2] No such file or directory 2025/05/06 22:01:08.000535 check 'log[/tmp/test.log]' is not supported: Cannot obtain information for file "/tmp/test.log": [2] No such file or directory 2025/05/06 22:01:08.716737 Zabbix Agent 2 stopped. (7.2.6)
Debug 5 is enabled nothing is written in the logs.
systemctl is also not failing.
Trying something stupid with Zabbix-server gives me:
# systemctl restart zabbix-server Job for zabbix-server.service failed because the control process exited with error code. See "systemctl status zabbix-server.service" and "journalctl -xeu zabbix-server.service" for details.
No error whatsoever however;
# systemctl status zabbix-agent2

Expected result:
Indicate in the agent/system log that the agent cannot start due to incorrect configuration.
