Templates Items Triggers Alerts dont work

[xris718]

Hi

I am running zabbix version 2.0. on a linux redhat server. The client is also a linux redhat server (kvm). Both can communicate back and forth just fine. The problem is that I have created a Template+Item+Trigger to monitor root space. When space fills up to 95% a trigger needs to be executed and alert sent out. I cant seem to get it working properly. Here is my setup.

Templates
-------------
Name: Template_KVM_Filesystem


Items
------------
Host: Template_KVM_Filesystem
Name: root fs < 10% left
Type: zabbix agent
Key: vfs.fs.size[/,free]
Type of information: Numeric (unsigned)
Data Type: Decimal
Units: B


Triggers
-------------
Name: root fs < 10% left
Expression: {Template_KVM_Filesystem:vfs.fs.size[/,free].last(0)}<10
Severity: High


The above template has been created and added to my client redhat server which looks like this from client view:

Items (the items are greyed out and cannot be changed)
-----
Parent items: Template_KVM_Filesystem
Host: kvmtest
Name: root fs < 10% left
Type: Zabbix agent
Key: vfs.fs.size[/,free]
Type of information: Numeric (unsigned)
Data Type: Decimal
Units: B

Triggers (the items are greyed out and cannot be changed)
--------
Parent triggers: Template_KVM_Filesystem
Name: root fs < 10% left
Expression: {kvmtest:vfs.fs.size[/,free].last(0)}<10



So my question is how come the above configuration is not working when space on my client redhat kvm server reaches above 95% and no alert gets triggered?

vfs.fs.size(/,free) is not the same as vfs.fs.size/,pfree). You aren't watching percent.
