JSON structured logs

Log files are system administrators’ best friends. Well, they are if they are understandable and useful. The problem with most log files, including most of the so-called “human-readable” ones, are very badly structured, and ultimately only truly understandable by a machine.

For that reason, in the past few years JSON-structured log files have become all the rage. Because they are easily understandable by a human being, and extremely fast to parse for a computerized log analyzer.

So, yes, in Syncplify Server! v6 you will find JSON-structured logs that look pretty much like this:

 }

In addition to that, while older versions of our software only supported logging to file or syslog, the next major version will support 4 log targets: file, syslog, database, or stdout.
