iostat, can I see mounted filesystem instead of disk device

[avraam jack dectis]

Hello,

I want to see io by filesystem, not disk device.

Iostat on other unix versions allow this. HP/UX iostat does not seem to. Is there a work around or a different command to do this?

Hi:

You could use 'glance'.

Great, that looks useful.

What I am looking for specifically is megabytes read and megabytes written per filesystem , as well as per disk.

I did see number of reads or writes in glance, but that was not translated into megabytes.

Shalom,

Can you post your results

Can you give background on what you are trying to achieve?

A file system is mounted on a disk device.

You can probably figure out which disk is hot by looking at the vgdisplay -v information for the volume group you are monitoring.

Thank you, that is very useful in determining which disk is which filesystem.

I was hoping to achieve an output that on one line listed the filesystem, percent busy the disk drives are, number of megabytes ( or equivalent ) read, number of megabytes ( or equivalent ) written.

I see however that I can piece it together from a number of commands, so that is good.

Thanks!

Hi,

Use glance, check the other option in glance
by which u can get the lvol wise load.

You can use Glance for exactly that information. GPM > Reports > Disk Info > IO by File System

That example used the GUI version - the same information is available in the graphical interface: glance > disk (F4) > next (F5) > next (F5) > IO by file system (F3)

"sar" is another useful tool for seeing I/O activity by HBA, disk, etc.

Hi,
You can run glance -i to get IO BY File System Report.

You can also run glance in adviser mode like below.

#cat myadviser

print GBL_STATTIME
fs loop
{
print "DEV Name:", FS_DEVNAME, " FS Dir:", FS_DIRNAME, " Physical Read Rate:", FS_PHYS_READ_BYTE_RATE, " Physical Write Rate:", FS_PHYS_WRITE_BYTE_RATE, " Physical IO Rate:", FS_PHYS_IO_RATE
}
print " "

#glance -aos ./myadviser
