[Announce] IOTop - I/O top-like monitor

iotop does for I/O usage what top(1) does for CPU usage. It watches I/Ousage information output by the Linux kernel and displays a table of current I/O usage by processes on the system. It is handy for answering the question "Why is the disk churning so much?".

Package page: http://maemo.org/packages/view/iotop/
This is actually latest iotop (official site), with some UI modifications to make it more usable on small screen. The process name was moved to the left part of UI and if you increase the terminal size, it will drop some additional information out, but keep name and basic IO info.

Handy - thanks for this :)

Re: [Announce] IOTop - I/O top-like monitor

Guys, i am noob at this, I/O stands for operations made with memory, not RAM, right?

Re: [Announce] IOTop - I/O top-like monitor

It doesn't install: couldn't find package.
Repos are enabled.

Re: [Announce] IOTop - I/O top-like monitor

Bit of a bug - got this when I tried to run it:

Code:

N900:~ $ iotop

 -bash: /usr/bin/iotop: /scratchbox/tools/bin/python: bad interpreter: No such file or directory

So I edited line 1 of /usr/bin/iotop so it reads:

Code:

#!/usr/bin/python

And it now works :)

Alfred - I/O stands for "Input/Output" - all hardware does it in some shape or form - disks, RAM, keyboards, video cards, usb sticks, printers, etc etc.

Yeah, I saw it as well. The autobuilder added this :( Will try to figure out why..

Re: [Announce] IOTop - I/O top-like monitor

I get the error:

Could not run iotop as some of requirements are not met:

Oh, I'm afraid it only works with kernel-power kernel.
Will add it to dependency, thank you.
