Zabbix 4 Network Monitoring - Third Edition

Human-readable constants

Using plain numeric constants is fine while we're dealing with small values. When an item collects data that is bigger, such as disk space or network traffic, such an approach becomes very tedious. You have to calculate the desired value, and from looking at it later, it is usually not obvious how large it really is. To help here, Zabbix supports so-called suffix multipliers in expressions—the abbreviations K, M, G, T, and so on are supported. This results in shorter and way more easy-to-read trigger expressions. For example, checking disk space for a host called host looks like this at first:

{host:vfs.fs.size[/,free].last()}<16106127360 

With suffix multipliers, it becomes this:

{host:vfs.fs.size[/,free].last()}<15G ...
