trigger, action about low free disk

[careeye]

Hi All,

I installed zabbix agent on linux server and windows 2003 server. They work fine now. Just a little problem, zabbix don't send notification email for low free disk. For other triggerl like machine was restarted or unreachable, I can get email. But for low free disk trigger, zabbix don't send mail on both linux and windows low disk trigger. For example, I set action for trigger "Low free disk space on Template_Linux volume /", and the status is "true" or severity is high, then send email to me. But when the trigger is true, zabbix did not send email to me. Is there anyone know this?

Aother questions is about trigger "Low free disk space on Template_Windows volume c:", the default expression is "{Template_Windows:vfs.fs.size[c:,free].last(0)}<10000", could anyone can tell me what 10000 means? Is it mens 10G? Because I tested on a server, only 64MB left on C driver, but the status of this trigger is still false! How can I make this trigger true if C driver is less than 500MB? Thanks.

Now it works.

{Template_Windows:vfs.fs.size[c:,free].last(0)}<10000

seems doesn't work.

I changed it to

{Template_Windows:vfs.fs.size[c:,free].last(0)}<1G

Then the status of the trigger is ture and I got the notification email.

could anyone can tell me what 10000 means?

It's 10000 bytes. Now that's what I call low free disk space ;-)

[careeye]

10000 means 10000 bytes. about 10KB. Ok, thanks.

another option:
*spesific to windows machine*

you can add:

PerfCounter = LogicalDisk:PercentFreeSpaceOnC,"\LogicalDisk(C:)\% Free Space",900
PerfCounter = LogicalDisk:PercentFreeSpaceOnD,"\LogicalDisk(D:)\% Free Space",900

on you zabbix_agentd.conf. And create trigger to alert you when machine has lower then 10% or 5%

[bashman]

Hi,

Is this trigger expression correct?:

{HOSTNAME:vfs.fs.size[/,free].last(0)}<500M

with a "Custom multiplier" = 1024

[bashman]

Works fine.

Hi,
I want to monitor and trigger the disk Free disk space for an average time 10 Mins with the threshold of free space less than 2 G . For this can i use the below parameter , it works if the threshold goes below 2G Immediately it is triggering the alert ,but as for the template it shoould wait for 10Mins ,if am wrong with the parameter please help me out...

BLR-NOC-06:vfs.fs.size[c:,free].avg(600)}<2G

Thanks,
Subbu

[bashman]

BLR-NOC-06:vfs.fs.size[c:,free].avg(600)}<2G

That should be fine. If you want to delay your trigger 10 minutes you can enable escalations with 600 seconds period. Take a look:

Hi,

I have problem to setup the this trigger (monitoring low disk space) on windows 2008.

Here is my configuration:

-=Item=-

type: zabbix agent
key: vfs.file.size[c:,free]
type of information: numeric (float)
units: GB

-=trigger=-
expression: {low disk monitoring for windows:vfs.file.size[c:,free].last(0)}<10G

The status said "Not Supported"

Could someone please advise how to fix it?

Thanks
Ricky

Got it working now.

change key: vfs.file.size[c:,free] to key: vfs.fs.size[c:,total]

[HullZabbix]

Got it working now.

change key: vfs.file.size[c:,free] to key: vfs.fs.size[c:,total]

I'm not quite sure you've got that correct. That's alerting you when the total disk size is over 10GB.

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%

Thanks for the reply. Yeah. I converted from % to total space. That works well
