Currently more and more people use Zabbix API, sometimes methods are used not in proper way. So it would be great to have the following type of Zabbix API debug. Debug should contain:
1. User session information (userid, sessionid... anything which can help to identify user)
2. Methods information (request data), like debug information in Zabbix frontend
3. SQL queries information (full SQL text, SQL response time, place from sources)

Maybe such information should be stored somewhere in physical log file.
