Where does zabbix store its history data?

[tfqzab]

Hello, my friends. I am using zabbix appliance 1.8.4. I want to select some special sets of historical monitor datas from zabbix. But I don't know where to fetch. I've connected to the mysqldatabase, it seems the history datas(for example, a interface's bandwidth datas in the past week) are not stored any database tables. So where does the history datas store? How can I select them?
Thanks in advance!

I can't imagine that the zabbix appliance would be any different from any other zabbix, although I could be wrong, but historical data is kept in the following tables:

history
history_log
history_str
history_str_sync
history_sync
history_text
history_uint
history_uint_sync

MrKen, maybe you're right. Thank you. I'll look into the details of the history tables and find the datas I want.
