====== Use Logging ======
Logging helps to understand what your running system is currently doing. Read about the possibilities of the logging framework in [[tools:logger:start|]]. 

In the EEROS library you will find a directory with examples. For this example see [[https://github.com/eeros-project/eeros-framework/blob/master/examples/logger/LoggerTest.cpp|LoggerTest.cpp]]. 

Open a shell in the build directory of your EEROS library and run 
<code>
$ ./examples/logger/loggerTest
</code>
This examples shows various log messages on different log levels. Study the code to understand how matrices and safety levels can be put into log messages.
