Space Usage Trigger is not working

[m.agios]

Hello team,
I am new in zabbix and i am trying to understand why the trigger of space usage of my Windows Server is not working.
I have some Windows Server where i have install agent2 and add them in the Template: Windows by Zabbix agent.
The trigger for disk usage for partion C is working but for the other partions does not work (D,E,etc).

I check in the Latest Data, i see this:


This data collection is used in the Trigger for usage space:




This specific disk is almost full for 1 month since i am trying to configure the trigger before increasing the size.

Please can you help me?
Thank you

add a host level macro {$VFS.FS.FREE.MIN.CRIT:"E:"} with value of 120G for example... that should cover your current free space and trigger might work...

It is pretty big disk. What's your values for those macros there?

Hi Cyber,

I am new in Zabbix and i can not find where to see the values of these macros. Can you guide me please?
Thanks

Template-> Macros -> there should be your macros... might also be that you have there similar macro but without ":E:" part... (or any letter).
Or <your host> -> macros -> inherited and host macros

Nothing for {$VFS.FS.FREE.MIN.CRIT} ???

I suppose it is on default value of 5G... So your trigger will not activate as you still have more than 5G of empty space and it does not change also...
if you digest the trigger... "if last percentage of used space is over 90 and ((there is less than 5g of space left) or (it will fill up in 1 day))". so first part is TRUE.. both parts in ()-s are FALSE... so "TRUE and (FALSE or FALSE)" => "TRUE and FALSE" => FALSE... trigger does not activate...

Trigger works on C drive probably because it is much smaller and its size also changes, which may indicate that it may fill up in a day...
