8 Unit symbols

Overview

Working with large values such as "86400", "104857600", or "1000000" can be challenging and can lead to errors. Therefore, Zabbix supports unit symbols (suffixes) that function as value multipliers.

The use of suffixes can simplify, for example, the configuration of trigger expressions, making them easier to understand and maintain.

Trigger expressions without suffixes:

last(/host/system.uptime)<86400
       avg(/host/system.cpu.load,600s)<10
       last(/host/vm.memory.size[available])<20971520

Trigger expressions with suffixes:

last(/host/system.uptime)<1d
       avg(/host/system.cpu.load,10m)<10
       last(/host/vm.memory.size[available])<20M

Suffixes can also simplify the configuration of other entities - item keys, widgets, etc. To see if a configuration field supports suffixes, always see the relevant page for the entity being configured.

Time suffixes

Zabbix supports the following time suffixes:

• 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 (trend functions only)

Memory size suffixes

Zabbix supports the following memory size suffixes:

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

Other uses

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

Zabbix server and frontend support the following unit symbols (suffixes):

• K - kilo
• M - mega
• G - giga
• T - tera
• P - peta (frontend only)
• E - exa (frontend only)
• Z - zetta (frontend only)
• Y - yotta (frontend only)
