Compiles added status messages sets the status.

If the status is STATUS_UNKNOWN, this will attempt to set the status based on expected value and threshold configurations. See \Drupal\monitoring\Sensor\SensorInterface::runSensor() for details.

Throws

\Drupal\monitoring\Sensor\SensorCompilationException Thrown if an error occurs during the sensor result compilation.
