Hi there.
I'm trying to get the IOPS for some linux devices (disks, LVM etc).
I could not find how the types are computed and I need your help.
For example, running:
$ /usr/bin/zabbix_get -s IP -p 10050 -k "vfs.dev.write[/dev/mapper/vg_os-lv_root,ops]"
Returns 2.850000. But what are those? Are not operations per second because iostat shows way more than that and the box is busy.
Also, running the above command, but for 5 min average returns 0:
$ /usr/bin/zabbix_get -s IP -p 10050 -k "vfs.dev.write[/dev/mapper/vg_os-lv_root,ops,avg5]"
0.000000
Can someone shed some light?
Thank you.
