public final class GemPrometheusLogger extends io.sbm.logger.impl.SbmPrometheusLogger implements GemLogger
Prometheus-backed GEM logger built atop SbmPrometheusLogger.

Provides the CLI arguments expected by GEM when launching remote SBK instances. Options returned by getOptionsArgs() are those the logger contributes to the command line. getParsedArgs() returns the concrete values based on the current logger configuration (time unit, latency bounds, CSV settings, metrics context).

  • Constructor Details

    • GemPrometheusLogger

      public GemPrometheusLogger()

  • Method Details

    • getOptionsArgs

      public String[] getOptionsArgs()
      List of logger-specific CLI options that GEM should include when composing the remote SBK command line.
      Specified by:
      getOptionsArgs in interface GetArguments
      Returns:
      array of option names (e.g., -time, -minlatency, -maxlatency, -csvfile, -context)

    • getParsedArgs

      public String[] getParsedArgs()
      Concrete logger arguments reflecting current configuration.

      If CSV is enabled, includes the CSV filepath; otherwise omits it. Always includes time unit, latency bounds, and the metrics context (port + context path).

      Specified by:
      getParsedArgs in interface GetArguments
      Returns:
      array of option/value pairs to be appended to the remote SBK command.
