8 Unit symbols

    Overview

    Instead of ‘86400’ for the number of seconds you can simply enter ‘1d’. Suffixes function as multipliers.

    Time suffixes

    For time you can use:

    • s - seconds (when used, works the same as the raw value)
    • m - minutes
    • h - hours
    • d - days
    • w - weeks
    • M - months (trend functions only)
    • y - years ( only)

    Time suffixes support only integer numbers (so ‘1h’ is supported, ‘1,5h’ or ‘1.5h’ are not; use ‘90m’ instead).

    • trigger expression constants and function parameters
    • constants of formulas
    • time period parameter of aggregate calculations
    • item configuration (‘Update interval’, ‘Custom intervals’, ‘History storage period’ and ‘Trend storage period’ fields)
    • item prototype configuration (‘Update interval’, ‘Custom intervals’, ‘History storage period’ and ‘Trend storage period’ fields)
    • low-level discovery rule configuration (‘Update interval’, ‘Custom intervals’, ‘Keep lost resources’ fields)
    • network discovery configuration (‘Update interval’ field)
    • web scenario configuration (‘Update interval’, ‘Timeout’ fields)
    • action operation configuration (‘Default operation step duration’, ‘Step duration’ fields)
    • user profile settings (‘Auto-logout’, ‘Refresh’, ‘Message timeout’ fields)
    • graph of Dashboards (‘Time shift’ field)
    • Administration → Housekeeping (storage period fields)
    • Administration → General → Trigger displaying options (‘Display OK triggers for’, ‘On status change triggers blink for’ fields)
    • Administration → General → Other (‘Login blocking interval’ field and fields related to communication with Zabbix server)
    • Zabbix server runtime control option

    Memory suffixes

    Memory size suffixes are supported in:

    • trigger expression constants and function parameters

    For memory size you can use:

    • K - kilobyte
    • M - megabyte
    • G - gigabyte
    • T - terabyte

    Other uses

    Unit symbols are also used for a human-readable representation of data in the frontend.

    • K - kilo
    • M - mega
    • G - giga
    • T - tera

    When item values in B, Bps are displayed in the frontend, base 2 is applied (1K = 1024). Otherwise a base of 10 is used (1K = 1000).

    Additionally the frontend also supports the display of:

    • P - peta
    • E - exa
    • Z - zetta
    • Y - yotta

    Usage examples

    By using some appropriate suffixes you can write trigger expressions that are easier to understand and maintain, for example these expressions:
