Logging events is important for every device connected to the Internet or a network. The syslog-ng application is an enhanced logging daemon, with a focus on portability and central log collection. It collects logs from many different sources, processes and filters them, and finally it stores them or routes them for further analysis. IoT developers can get started with it quickly, as its configuration language is similar to programming languages.

From this session you will learn how to use logging for collecting usage statistics, monitoring, security, or debugging running applications, using examples from syslog-ng. We will discuss some interesting use cases from a wide range IoT devices: consumer devices, like the Amazon Kindle or the BMW i3 electric car IT appliances, like NAS and network devices industrial uses, like National Instruments devices

In addition to acting as a logging agent, syslog-ng can be your logserver and collect data from IoT devices. The syslog-ng application can parse incoming data for interesting information, anonymize it if required by compliance, and route results to the proper destination. Other than saving logs locally, you have many possibilities, including visualizing logs using Graphite, creating alerts using Riemann, analyzing them in Kibana, or saving them to Hadoop HDFS for long term storage.
