TaskMonitor Pro

It has two main options:

- It shows a chart and several labels wherein the values of the CPU and memory usage are updated every 0.5, 1, 2 or 4 seconds.

- It can record on a CSV file the read values for a later usage on a spreadsheet program.

When TaskMonitor Pro is running on the background it consumes little resources. Then it can monitor and record the CPU and memory usage of other applications on the foreground.

In order to get the CPU usage the app does not make use of the 'Top' command from Linux but instead it parses the '/proc/stat' file and work the calculations out with the user and system time.
