v2 disk monitor problem

[valferon]

Hello,

I'm trying to setup hard disk monitoring on my server using zabbix latest version (2.0).

I'm using "UserParameter" in zabbix_agentd.conf. For some of them it works, for others, it doesn't.

Here are the user parameters I use :

- this one works :

UserParameter=custom.vfs.dev.read.ms[*],cat /proc/diskstats | grep $1 | head -1 | awk '{print $$7}'

Both CLI and zabbix frontend get my datas and it works just fine.


- this one doesn't work

UserParameter=custom.vfs.dev.disk.use[*],iostat -xk 1 2 | grep sda |tail -n 1 | sed -e's/  */ /g' | cut -d ' ' -f 12

Frontend shows "no data" and turn my item from enabled to not supported after few seconds.
CLI works though so it's quite strange :

zabbix_get -s 127.0.0.1 -k custom.vfs.dev.disk.use[sda]
4,40

Of course zabbix's item name are the same in the frontend and the config file.

Thanks !

Any idea?
Thanks for your help!

4,40 don't look like an understanable number to zabbix.
your script should return 4.40 (notice the dot).

you either have a problem with your script or your system locale . try adding a LANG=C in your agent's startup script

Thanks for help Ghoz!

So I tried LANG=C, zabbix_get no longer return a "," but "." so it should be alright.

But, still having the same problem and zabbix_agentd.log shows :

   869:20120611:093531.803 Requested [custom.vfs.dev.use[sda]]
   869:20120611:093531.803 Sending back [ZBX_NOTSUPPORTED]

Even if :

zabbix_get -s 127.0.0.1 -k custom.vfs.dev.disk.use[sda]
5.94

( UserParameter=custom.vfs.dev.disk.use[*],iostat -xk 1 2 | grep sda |tail -n 1 | sed -e's/ */ /g' | cut -d ' ' -f 12 )

[ghoz]

check your item name : according to the logs, you configured zabbix with

custom.vfs.dev.use[sda]

while the agent and your manual check uses

custom.vfs.dev.disk.use[sda]

Once more, thank you for help

It returns good values now so it's alright for me now.
