Free monitor software for mac

iTunes 4 introduced the ability to share music between computers. However, as of version 4.1, iTunes doesnt provide much information about who is connected or what is being shared. This utility monitors iTunes to provide a solution.
The iTunes application must be named "iTunes." In order to be recognized as music files, file names must have one of the following extensions: .wav, .wma, .sn2, .mov, .moov, .mp3, .aiff, .m4a, or .m4p. The iTunes Monitor cant associate a shared music file with a given remote user and files being accessed locally arent distinguished from those being shared. iTunes monitor cant display the name of a file which is being received. iTunes Monitor may not work properly if another application is being used to proxy music streams over the Internet (iTunes 4.0.1 only.)
Since lsof (the UNIX tool at the core of this application) doesnt reliably return complete path names, iTunes Monitor must scan your Music folder when a new file is encountered. It may take a few seconds after launching before it completes its analysis of the files and sockets iTunes is using and initially displays the information.
Enhancements:
- Added support for multiple music folders.
- Bug fixes: fixed memory leaks, improved responsiveness, fix for Panther.

CPU Load Monitor is a gadget that shows your CPU load.

It also has a timer.

Battery Monitor is a simple application that records the performance of your battery over a discharge cycle by writing the power and estimated remaining time to a text file every minute. You can then use this list of values to see if it works as it should. (E.g., does it discharge fully or does it break down prematurely?)

Note that this tool does nothing magical. It simply records to a file what you can see when you use a stop watch and look at the battery indicator in the control strip or menu bar.

Since the values of every minute get recorded, you can use the output also to iport into a spreadsheet for making nice graphs. Its up to you to figure out how to do that.

Service Monitor works with our PowerKey and Kick-off! products to ensure that internet services running on a computer keep working.

Service Monitor works by periodically querying the chosen services running on this computer, and verifying that they respond as desired. As long as they do, Service Monitor updates a "Rebound! Timer" in the PowerKey/Kick-off! software. If the service fails for any reason, Service Monitor stops updating the corresponding timer, and PowerKey/Kick-off! can take appropriate action to restart the computer.
