Examples with MqttLogMsgBuilder org.openmuc.framework.datalogger.mqtt.util.MqttLogMsgBuilder used on opensource projects

Example 1 with MqttLogMsgBuilder

use of org.openmuc.framework.datalogger.mqtt.util.MqttLogMsgBuilder in project OpenMUC by isc-konstanz.

the class MqttLogger method log.

@Override
public void log(List<LoggingRecord> loggingRecordList, long timestamp) {
    if (!isLoggerReady()) {
        logger.warn("Skipped logging values, still loading");
        return;
    }
    // logger.info("============================");
    // loggingRecordList.stream().map(LoggingRecord::getChannelId).forEach(id -> logger.info(id));
    // FIXME refactor OpenMUC core - actually the datamanager should only call logger.log()
    // with channels configured for this logger. If this is the case the containsKey check could be ignored
    // The filter serves as WORKAROUND to process only channels which were configured for mqtt logger
    List<LoggingRecord> logRecordsForMqttLogger = loggingRecordList.stream().filter(record -> channelsToLog.containsKey(record.getChannelId())).collect(Collectors.toList());
    // channelsToLog.values().stream().map(channel -> channel.topic).distinct().count();
    // Concept of the MqttLogMsgBuilder:
    // 1. cleaner code
    // 2. better testability: MqttLogMsgBuilder can be easily created in a test and the output of
    // MqttLogMsgBuilder.build() can be verified. It takes the input from logger.log() method, processes it
    // and creates ready to use messages for the mqttWriter
    MqttLogMsgBuilder logMsgBuilder = new MqttLogMsgBuilder(channelsToLog, availableParsers.get(parser));
    List<MqttLogMsg> logMessages = logMsgBuilder.buildLogMsg(logRecordsForMqttLogger, isLogMultiple);
    for (MqttLogMsg msg : logMessages) {
        logTraceMqttMessage(msg);
        mqttWriter.write(msg.topic, msg.message);
    }
}

Example 2 with MqttLogMsgBuilder
