Glance output

[haux]

Hi every one,

I usually use glance for performance supervission on our RP8400,

With option "v" "IO By File System" I see:

32 /oradata/vol10 /dev/vg_oracle/lvol10 vxfs 148.9/231.3 234.6/238.3

I can' understand how to understand what 234.6/238.3 AND 148.9/231.3 mean ?

does it mean min/max ? or avrage/max ?

Regards.

Haux,

Using the 'help' function from glance it explains the column headings for the 'current screen metrics'

On my version of glance (3.71) , IO by filesystem is "option i"

In this case the headings are: Idx - File System - Device - Type - Logl IO - Phys IO

You are enquiring about Logl IO (FS_LOGL_IO_RATE / FS_LOGL_IO_RATE_CUM) and Phys IO (FS_PHYS_IO_RATE / FS_PHYS_IO_RATE_CUM) - see the help screen for the technical details. Essentially you are looking at an IO rate (IOs per second) for the interval and an average collected over the cumulative collection time (varies depending on when process started vs glance started - or last reset)

Hope this helps
