Would it be possible to add a zabbix process association in the Documentation, in order to help us know which Zabbix_Process we need to increase the log-level for debugging.
For example, a one-line in Zabbix-Agent items may indicate that if you need to enable debugging fot this item in the log file, then you need to increase the logging for the "Polling" zabbix process.
Under Zabbix-Agent(Active), you would need to log the "Trapper" process
Under Discovery, Need to log the "Discovery" process, but does not include the "LLD" discoveries, need to enable "Poller" or "Trapper" for those.
Under External Scripts --> Poller
The issues I have when debugging is that I'm often not sure I'm even increasing the logging for what I need to debug.
