Note: The name of a disabled host is displayed in red (in both the host dropdown and the list). Data of disabled hosts is accessible starting with Zabbix 2.2.0.
Starting with Zabbix 3.2.4, only values that fall within the last 24 hours are displayed by default.

It is also possible to change this limitation by changing the value of ZBX_HISTORY_PERIOD constant in include/defines.inc.php.
