vfs.dev.read/write Types

[ahanson]

I want to add Disk I/O monitoring for a Linux machine. I got a simple "vfs.dev.read[hda1]" key to work, which I guess defaults to either "operations" or "sectors" depending on which post you read. Could I get some clarification on this, and any other options for this key.

I really just want to see if Disk I/O is becoming a bottleneck.

on linux the default is sectors:

from src/libs/zbxsysinfo/linux/diskio.c:

if(mode[0] == '\0')
{
/* default parameter */
zbx_snprintf(mode, sizeof(mode), "sectors");
}

Thanks so much for that response.

Now my only question is, what other options are there? I know of operations and sectors, is that all?
