PerfMon is a "floating" performance monitor tool. It shows on top of any other app you are running. Aside from being useful for powerusers wanting to know what their device is doing, it is a great tool to use during debugging and profiling.

PerfMon offers you four categories of metrics:

- Foreground App
- CPU
- Disk I/O
- Network I/O

PerfMon will also show you a new and unique-to-PerfMon performance metric: "CPU Capacity Usage". The CPU usage percentage traditionally used to measure and compare how much of the computational resources an app (or the entire device) is currently using does not make sense in a mobile multi-core setting. The capacity metric will take the CPU usage and scale it to what it would be if all cores were running at full capacity.

For example: if you have a 1.6ghz quad-core running a light app, it could be using 10% CPU with only one of the four cores active, and that core running at 200mhz. If you translate that to all four cores running at 1.6ghz, that app is using only 0.3% of total CPU capacity.

It's the only CPU Usage metric that makes any sense!

Foreground App

This window shows metric of the currently foreground (running and visible) application:

- Application title
- Application package name
- Memory usage total (in megabytes)
- Dalvik, Native, and Other memory usage (in megabytes)
- Overall CPU Usage (normal percentage and capacity)
- User and System CPU Usage (normal percentage)

CPU

This window displays overall CPU metrics:

- Capacity usage and current divider
- Overall CPU usage percentage
- Per-core CPU usage percentage and megahertz

Disk I/O

This window displays the disk I/O metrics of your MMC-based storage devices. Usually, mmcblk0 is your internal flash, and mmcblk1 is your removable SD-card. Please note that currently MTD-based storage is not supported by this display. Also note that the metrics displayed are raw I/O, so if the OS has I/O requests buffered/cached, you will not see anything happen here.

- Per-device read and write kilobytes/second

Network I/O

This window displays the network I/O metrics of your network interfaces.

- Per-interface transmit (Tx) and receive (Rx) kilobytes/second

Download

Download from Google Play

The Google Play download is not free - it costs about a beer (thanks!). The download listed below is 100% the exact same program, but free. If you are able to purchase on Play, please consider that these tools don't write themselves, and beer is an essential fuel to the Chainfire.

REDISTRIBUTION IS NOT ALLOWED
(you can link to this thread, but you can't repost the APK elsewhere, you can't include it in your ROMs, etc)

( < 1.1: 512 )

This must be the only time, in all my years on xda, that I have seen anyone give a valid reason as to why they were using a placeholder....

Also, first!!!

Nice tool!

Just a suggestion, there's random red lines blinking when refreshing the window and is a little bit ugly :P

I'm using a highly customized rom in a sgs2 (chamaleon 1.3), maybe that is the problem...

Doesn't happen on any of the 15 devices running stock ROMs I've tested it on.
