Server says not supported but agent returns value

[vj88]

Hi,

I'm trying to get the value of space free (in percentage) of a scsi mount point.
The key i'm using is "vfs.fs.size[/home/backup/database.backups,pfree]" (without the quotes)
Now if i run "zabbix_agent -t vfs.fs.size[/home/backup/database.backups,pfree]"
I get "vfs.fs.size[/home/backup/database.backups,pfree] [d|84.001203]" on the host.

But if i run the zabbix_get variant t on the server i get ZBX_NOTSUPPORTED

The server is version 2.0.5 and the agent is 2.0.4.

Any help on what is going on.

Thanks

Please , post in this tread output of both commands(and from client and from server):

zabbix_get -s YOUR_HOST -k vfs.fs.size[/home/backup/database.backups,pfree]
zabbix_agent -t vfs.fs.size[/home/backup/database.backups,pfree]

Also check in your zabbix_agentd.conf option Server

Client:
Command: zabbix_agent -t vfs.fs.size[/home/backup/database.backups,pfree]
Result: vfs.fs.size[/home/backup/database.backups,pfree] [d|83.309983]

Server:
Command: zabbix_get -s 192.168.0.199 -k vfs.fs.size[/home/backup/database.backups,pfree]
Result: ZBX_NOTSUPPORTED

I checked the server config and all the ip addresses are pointing to the correct location. Plus i don't believe that would be the issue as there is a lot of other things that the agent is sending the server. So other items are all fine. Its just this one item that is not getting data.

So..... Nothing then.

What in your zabbix_agent.log In Debug=4 when you get vfs.fs.size[/home/backup/database.backups,pfree] key?

[vj88]

Ok, here are the results from the log file

3490:20130502:123226.745 Requested [vfs.fs.size[/home/backup/database.backups,pfree]]
3490:20130502:123226.745 Sending back [ZBX_NOTSUPPORTED]

Which is weird cause if i run zabbix_agent -t vfs.fs.size[/home/backup/database.backups,pfree] which i copied and pasted from the log, i get the correct info.

Try running this command from a user under which the zabbix agent runs.

Ok that actually provided the same error (the "zbx_notsupported" error) on the agent when run under the zabbix user. Ok so its a problem with the permissions. Except I don't know what permissions the zabbix user actually needs to get this info.

What OS do you use?

[vj88]

That particular box, Linux.

[neogan]

Could you show me

ls -al /home/backup/database.backups

Configure sudo so that the zabbix user can execute your script as root, then prefix the command with sudo

[vj88]

Ok I'v got it working now. I just gave the folders 755 permission and now the zabbix user (aka the zabbix agent) can now get the required information.

Thanks
