Zabbix: What does "Questions" mean in "MySQL Command Counters"?

I have Zabbix monitoring a MySQL server, the MySQL Command Counter chart is nice, but a large portion of the graph shows massive Questions, Unlike SELECT or INSERT, what does Question mean in MySQL & Zabbix?


According to the docs at http://www.zabbix.com/documentation/1.8/manual/cookbook/specific, "questions" appears to be just a total of any queries (including SELECT, INSERT, etc.).


Questions is the sum of all queries performed by MySQL Db. Is very usefeul when you need perform tuning on data base side.
