      Returns:
      the metrics service
    • getBaseName

      String getBaseName(Measured measured)
      Parameters:

    • getMetricsSnapshot

      JsonObject getMetricsSnapshot(Measured measured)
      Will return the metrics that correspond with the measured object, null if no metrics is available.

      Returns:
      the map of metrics where the key is the name of the metric (excluding the base name unless for the Vert.x object) and the value is the json data representing that metric
