I've installed Zabbix on Ubuntu.

Although I can see a "graph" and related "latest data" for all network interfaces in Zabbix front-end, there is no data for them when I directly query MySQL database!!!!

mysql>select value from history where itemid=**23717**

Empty set(0.00 sec)

23717 is one of the itemid's for my network interfaces.

actually there are lots of info in front-end (graph & latest data) but the query return no value.

however another itemid i.e "cpu usage" is OK.

please help me.

You are querying the wrong table - that item is probably set to be "Numeric (unsigned)", and you should query the history_uint table instead.
