file system monitoring

[yngvith]

Hi, I'm new to zabbix. So, I've just installed a zabbix server vesion:
zabbix_server --version
Zabbix server v2.4.7 (revision 56694) (12 November 2015)
Compilation time: Nov 13 2015 11:41:19
the server is ubuntu 14.04 LTS, kernel 3.13.0-68-generic

I've installed agent on several nodes (also ubuntu 14.04 LTS, kernel 3.13)

But, I'm not seeing zabbix report correctly on full file systems. i.e.
when I test this by creating files on file system /var/log
os it's 98% full, zabbix only tells me:
"free disk space is less than 20% on volume /var/log ( the colour is orange)

Also, when this volume is 100% full ( /var/log ) zabbix is only reporting :
"free disk space is less than 20% on volume /var/log" ( the colour is orange)

why is'nt this reported as 'high' with a Red colour?

best regards

I suggest to get familiar with concepts of Zabbix first. The online documentation is a very good starting point.
Regarding your question take a look at Items and Trigger in particular.

The short answer to your question is that your Trigger likely has 20% statically defined in its name.

E.g.: Free disk space is less than 20% on volume {#FSNAME}

and the expression of the Trigger just checks the last value of the respective Item being below a certain threshold.

E.g.: {Template OS Linux:vfs.fs.size[{#FSNAME},pfree].last(0)}<20

Note that Items and Triggers related to file systems in the Template distributed with Zabbix are managed by so called Low-Level discovery.

As being new to Zabbix, you might possibly also be interested in Some principles and practices I consider useful (not only) when using Zabbix at larger scale.

OK, so I've created a new 'trigger prototype' under the relevant template->discovry ...
and it works
thanks a lot for your help

Or u can juste write a powershell script (for instance) and then with the zabbix trapper you retrieve all the informations. I did this, I think it's the easiest way to do it !
