Kronos is a simple periodic task scheduler. Each task is run in a separate thread. Task is written as a C++ class in a Kronos module, example of a simple module is here. The scheduler has been tested on Ubuntu 14.04. The scheduler can be compiled and run on OSX, but some modules will not work on OSX.

cmake . && make

The binary will be generated in src/core directory and it will be called kronos.

From root of the tree run

./src/core/kronos

The scheduler will start running the default modules:

• test.cpp: just prints "hello world" every 10s
• memory.cpp: prints and stores VM size of the process in database every 5s
• tcp_connect.cpp: stores time to estabish tcp connection to google.com every 5s

To undrestand where the data is stored please go through the code for the test.cpp module.

Writing a new module is simple. You just need to add a new .cpp file in the modules directory and extend the ModuleInterface or the PersistModule class and provide a run() method. In Case of PersistModule you also need to specify the name of the database table where you want to persist the data. Please refer test.cpp for further details and comments.
