 ## Analytics Channel ANALYTICS
 The analytics channel provides processed collected during the whole execution cycle. Information yield by this channel are derived by a LoggingContext where logging metadata are stored.
 
-Statement time analytics provide information about which statements were called during the program execution, how much time was spent totally to execute that statement and how many times each one was hit.
