vfs.fs.size - Wrong Value

[Zophren]

Hello !

My Zabbix Server version => 1.8.11 (Debian) 64Bits
My Zabbix client version => 1.8.2 (Debian) 64Bits

I try to use the Items "Free disk space on /" => vfs.fs.size[/,free]

When i launch a "df -lh" on the client, i have this result :

Sys. de fichiers    Taille  Uti. Disp. Uti% Monté sur
/dev/sda1             9,8G  5,7G  3,6G  62% /

When i launch this " zabbix_agentd -t vfs.fs.size[/,free]" on the client, i have this result :

3848830976 Bytes => 3.8GB

When i launch this on the supervision server "zabbix_get -s toto.server.fr -k vfs.fs.size[/,free]", i have this result :

3848830976 Bytes => 3.8GB

So, all it's ok but in the Web portal (Last Data), i have this :



16GB ??? I don't understand why, this value is wrong ... Problem when the agent stock the value in the BDD ?

Is it from default zabbix template for Linux?

Could you attach the screenshot of setting your problem item?

[Zophren]

Hello,

Thanks for your interest, i'm use the default linux template :

What in the lastest data?
(I mean Monitoring -> Lastest data: click Graph, next choose Values) Attach the screenshot here.
What version web frontend do you use?

[Zophren]

Zabbix => 1.8.11

The screenshot in attachment ... The value is wrong relative to the agent Value ....

[Zophren]

Someone have a solution ?

Are you sure that you look latest data to correct server (toto.server.fr)?

[Zophren]

Yes of course .

I have the same problem on all my server ...

I seem to recall an issue of that nature in one of the 1.8.x agents.
Any chance you can upgrade the agent to match your Zabbix server release on at least one of your problem machines and see if that fixes the problem?

[Zophren]

Yes, it's a good idea, thank for your experience !

The version on the debian repository is mine (1.8.11), i will compile a most recent version and keep you posted !

I thinking about your comment during the night ... I don't think the problem is on the Zabbix agent, because he has the good value :

When i launch this " zabbix_agentd -t vfs.fs.size[/,free]" on the client, i have this result :

3848830976 Bytes => 3.8GB

When i launch this on the supervision server "zabbix_get -s toto.server.fr -k vfs.fs.size[/,free]", i have this result :

3848830976 Bytes => 3.8GB

However, the problem is localized when the server record the value in the database OR when he shows it in the Dashboard ...

[Heilig]

At your place I would updated the zabbix server and agent to the latest stable version (as advised by tchjts1).

[Zophren]

Update to 2.0.6 in progres ... The database update take many times ...

I keep you posted

[Zophren]

I upgraded to Zabbix Frontend 2.0.6 and Zabbix agent 2.0.6 ...

I still have the same problem.

When i launch this on the supervision server "zabbix_get -s toto.server.fr -k vfs.fs.size[/,free]", i have this result :

3848830976 Bytes => 3.8GB

And on the Dashboard, i still have :

Arghhhhhh ....

Any idea ?

[Heilig]

Hmm, interesting.
If you remove "B" from "Units" in item configuration, what then displays this item in the latest data?

P.S.: do I understand correctly that your zabbix server is upgraded, too?
