This is a simple python script that creates logs to monitorize CPU usage on multicore machines. It works with the help of top, so of course, you will need to adapt the parser to your top output.
There are two versions of the script. This is because the first saves CPU since it loads the data on memory and at the end, that data is dumped to a file. The second one writes the logs on each meassure so it saves memory, but it sacrifices CPU.
You can launch the script at any moment, it will take the data from the top command and store it. In the first version, when you press ctrl+c the executions of the script will stop and two files will be created, while in the second these are built incrementally.
One of these files contains a detailed dump with the 10 programs that were using the CPU the most on the moment of the meassure, a list with all the core level of usage and a date and time string. The other one is formated as CSV, ready to be loaded on some ploting tool to display the core usage.
There are a lot of things to improve here, but this is not the first thing on my list so... Anyway, here you have the main features that should be added.
- Code again the parser part to make it modular and develop a way to easy select the parser, or even create one.
- Replace the memory and file storage for the meassures. A better option will be using a db to store the information.
- The way of finishing the script is not the best.
