Type support: getting started with syslog-ng 4.0
Version 4.0 of syslog-ng is right around the corner. It hasn’tyet been released; however, you can already try some of its features. The largest and most interesting change is type support. Right now, name-value pairs within syslog-ng are represented as text, even if the PatternDB or JSON parsers could see the actual type of the incoming data. This does not change, but starting with 4.0, syslog-ng will keep the type information, and use it correctly on the destination side. This makes your life easier, for example when you store numbers to Elasticsearch or to other type-aware storage.
