The data on my graph and "Latest Data" screen in the Web GUI does not match what is stored in the database.
For example... currently all the "Latest Data" on this item says "116.47MB" (the item is set to multiply the data by 1000) but the database actually has the correct values...
MariaDB [zabbix]> select value from history where history.itemid = "35835";
4 rows in set (0.00 sec)
So instead of 116.47MB I would expect to see 122.01MB.
This is running on a CentOS 7.3.1611 server and the actual Zabbix version is 3.2.3
