Trigger of percentage of free disk space

[alexand3r]

Hey everone !

I need help on something that looks reall simple to fix but I do not have any clue on how to do it.
Here is the thing, I already receive alerts on my zabbix server when the hd of my servers are too low on free disk space, but it works on the quantity of size that remains.

I'd like this trigger to work on the percentage instead.

Like if I have less than 10% of free disk space, then I receive an alert.

Do you know how I could manage to get this ?

Thank you for your answers !!

You can:

• create a Zabbix agent item with key

  vfs.fs.size[<fs>,pfree]

  (replace <fs> with actual filesystem name)
• create a trigger that uses this item.

As above,

I posted this on another thread if it's any help for you:

ITEMS:
vfs.fs.size[c:,total] is going to give you the overal size of the C drive
vfs.fs.size[c:,pfree] is going to give you the percent of free space
vfs.fs.size[c:,free] is going to give you the size of the free space

TRIGGER:
{machinename:vfs.fs.size[c:,pfree].last(0)}<5
That will trigger when the disk space percentage is less than 5%

Thank you guys ! I've tried your solutions and it worked !

I used pfree like this

{xx:vfs.fs.size[h:,pfree].last(0)}<5

And it's perfect for what I wanted to do !

Is there any "variable" to replace the letter of the file system ?

Like a generic item, and zabbix will turn this variable depending on which letter he founds, and make several triggers depending on the number of drives he get.

Oh nevermind i managed to lower the default discovery triger.

Sry !
