Calculated Items in Low Level Discovery Rules


We can also extend discovery rules with calculated items.

In this example we will add a calculated item to show the change in bytes for each #FSNAME in the Windows by Zabbix agent active ⇾ Mounted filesystem discovery rule.

In the Mounted filesystem discovery rule, create a new Item Prototype.

Key Value
Name {#FSNAME}: Used Changed
Type Calculated
Key usedChanged[{#FSNAME}]
Formula change("vfs.fs.size[{#FSNAME},used]")
Type of information Numeric (float)
