Logger

The logger component writes the values of DDS topics as time series to netCDF log files. The main sections of the input file are:

• Options:
  • PeriodMs: The period between writing to file, in milliseconds.
• LogSetup: The signal-independent configuration of the logger.
  • Maxsamples: The number of samples before further samples are written to a new NetCDF File.
  • CompressionLevel: The NetCDF compression level, an integer between 0 and 9.
  • Directory: A string specifying the directory where the log files should be written.
  • FilePrefix: The prefix for the files.
  • Title: Title of the log file series.
  • Origin: Typically name of the ship.
  • OriginType: Typically 'ship'.
  • OriginId: Typically the IMO number or another ID.
  • Summary: A short description of the data series.
• Signals: A list of signals to write, with the following fields:
  • Type: The data type of the signal, e.g. DoubleVal, PosInfo, Float3. Available types can be found here.
  • Topic: The topic name
  • Unit: The unit of the signal. This is currently for reference only.
  • Partition: The DDS partition to find the signal.
  • DdsSelectQuery: A DDS query to perform to find the signal.

Available DDS-types can be found here
