21 Suffixes

It is possible to simplify Zabbix trigger expressions or item keys by using suffixes.

Standard multipliers

The following table summarises available standard multipliers in Zabbix frontend and server:

Server K (Kilo)
M (Mega)
G (Giga)		 T (Tera)
Frontend K (Kilo)

Time-related multipliers

Since Zabbix version 1.8.2 the following time-related multipliers are available:

  • s - seconds; when used, works the same as raw value;
  • m - minutes;
  • h - hours;
  • d - days
  • w - weeks.

These are supported in trigger expression constants and function parameters, as well as in the internal item zabbix[queue,<from>,<to>] parameters.

Examples

These multipliers allow to write expressions that are easier to understand and maintain, for example the following expressions:

{host:zabbix[proxy,zabbix_proxy,lastaccess]}>120
{host:system.uptime[].last(0)}<86400
{host:system.cpu.load.avg(600)}<10

could be changed to:

{host:zabbix[proxy,zabbix_proxy,lastaccess]}>2m
{host:system.uptime.last(0)}<1d
{host:system.cpu.load.avg(10m)}<10
