20 Frontend definitions

While many things in the frontend can be configured using the frontend itself, some customisations are currently only possible by editing a definitions file. Located in the frontend directory, this file is include/defines.inc.php. Parameters in this file that could be of interest to users:

  • TRIGGER_FALSE_PERIOD

For how long to show triggers in OK state after their state changed from PROBLEM, in seconds.

Default: 1800

  • TRIGGER_BLINK_PERIOD

For how long a trigger should blink after its state changed, in seconds.

Default: 1800

  • ZBX_PERIOD_DEFAULT

Default graph period, in seconds. One hour by default.

  • ZBX_MIN_PERIOD

Minimum graph period, in seconds. One hour by default.

  • ZBX_MAX_PERIOD

Maximum graph period, in seconds. Two years by default since 1.6.7, one year before that.

  • GRAPH_YAXIS_SIDE_DEFAULT

Default location of Y axis in simple graphs and default value for drop down box when adding items to custom graphs. Possible values: 0 - left, 1 - right.

Default: 0

  • ZBX_UNITS_ROUNDOFF_THRESHOLD

Threshold value for roundoff constants. Values less than it will be rounded to ZBX_UNITS_ROUNDOFF_LOWER_LIMIT number of digits after comma, greater to ZBX_UNITS_ROUNDOFF_UPPER_LIMIT.

Default: 0.01

  • ZBX_UNITS_ROUNDOFF_UPPER_LIMIT

Number of digits after comma, when value is greater than roundoff threshold

Default: 2

  • ZBX_UNITS_ROUNDOFF_LOWER_LIMIT

Number of digits after comma, when value is less than roundoff threshold

Default: 6

  • ZBX_HISTORY_DATA_UPKEEP (available since 1.8.4)

Number of days, which will reflect on frontend choice when deciding which history or trends table to process for selected period on data graphing. When this define is:

  • less than zero - zabbix takes item values for selected graph period configured in item “keep in history” field to make calculations;
  • equal to zero - zabbix takes item values only from trends;
  • greater then zero - zabbix overwrites item “keep in history” configured value with this define;

This define could be useful for partitioned history data storage.

Default: -1

  • ZAPCAT_COMPATIBILITY

Enables support for Zapcat Zabbix Java JMX bridge item keys syntax

Default: false

ZAPCAT_COMPATIBILITY is only available for 1.8.4.
