iostat

Hi,

Just would like to know if somebody suceeded to use the vfs.dev.read or write key on a linux box with /dev/sda disk.

I tried that:
vfs.dev.read[sda,,avg15] and vfs.dev.read[sda1,,avg15], but it doesn't seem to be supported.

It's a server where the bottleneck is i/o, so I would like to be able to monitor it.

Before going to use an userparameter with iostat and awk commands, I would like to know if somebody experience the same problem.

Thank you

Jean

On Linux avg{1,5,15} modes are do not supported (IIRC avg modes are supported only on *BSD).
You can only use vfs.dev.{read,write}[sda1,sectors] or vfs.dev.{read,write}[sda1,operations].
Dist Unix_t template is IMO unusable on Linux.

Thank you for your help.

I agree with you about the fact that zabbix agent "out of the box" is not able to get a lot of interresting metrics for disk monitoring.

I am going to be obliged to do some UserParameter script, with iostat...
