monitor disk usage

[MrKen]

. . . when i go to create a new ITEM it does not show the key i need to use (pfree nor puse)... anyway to get it again?

Actually it is there, but it is hiding. At the bottom of the Zabbix Agent list of keys you will see vfs.fs.size[fs<,mode>]. See the manual P.107 :

fs - filesystem, mode
- one of total
(default), free, used,
pfree (free,
percentage), pused
(used, percentage)

oh ok... got it thx

[Kai-Kai]

Can you show us screenshots of the configuration of you item, and of your trigger ?

You may want to set "Type of information" to Numeric(float) as you get percentage, which is not always integer: 10.34.

[Kai-Kai]

Yes, put the information to float.
And, another thing is wrong... your test. If you want to receive a notification when the / is 80% full, the trigger should be <20 and not <80.
(80% full == 20% free, so pfree <=20).

[ulises]

ok I just changed it to float... I used <80 just in order to test -- which means it will send alert if disk is 20% used :-)

however, the partition is 22% used and is not sending the event

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 2.9G 586M 2.2G 22% /

Are you sure you don't have a notification in the "non classified" column, on the line corresponding to the group of your machine ?
Is the monitoring of your machine well active ?
Is the item still active ? What about the walues collected on the "last metrics" screen ?
