This Node.js application uses Amazon Kinesis Streams and MongoDB Atlas to process log data from a SYSLOG file. The application consists of two parts: the producer, which generates sensor readings and sends them to a Kinesis stream; and the consumer, which reads records from the stream, adds some metadata to each entry, and stores it in MongoDB Atlas. The example uses the AWS SDK for Node.js and the MongoDB Node.js driver. It also includes an agent that can monitor files and send their contents to a Kinesis stream, providing a simple way to process log data without writing custom code.
