    Zabbix Calculated Item

    Hello there,

    1st time posting here , ive looked for something similar to my problem but couldnt find any.

    I want to make a graph to show the disk read and write in MB's

    I created the item for it

    KEY - perf_counter_en["\PhysicalDisk(_Total)\Avg. Disk Bytes/Read",60]
    Numeric Float

    And this item works

    And when i preview the graph its showing in K , from what ive researched this is giving me the data in kilobytes , so since im not that bad in math i tryed the following

    create a new item calculated and in the formula last("PhysicalDisk.AvgDiskBytesRead")/1024 since that was the name i gave the item , ive tryed with the item ID but it always gives me the error of
    • Incorrect value for field "Formula": incorrect usage of function "last".

    i even tryed last(perf_counter_en["\PhysicalDisk(_Total)\Avg. Disk Bytes/Read",60]) / 1024

    and i cant find anything with this. im using Zabbix 6.4.12rc1.

    If anyone can give me direction or an alternative i would be much apreciated
Working...
