This guide describes the use of the following syslog-ng versions:
syslog-ng Open Source Edition (OSE) v3.0.x
syslog-ng Premium Edition (PE) v3.0.x and later, including syslog-ng Agent for Windows v3.0.x and later
syslog-ng Agent for IBM System i
Most of the guide applies equally to both the Open Source and the Premium editions of syslog-ng, with the following exceptions:
The syslog-ng agent for Microsoft Windows is available only as part of the Premium Edition.
Disk-based buffering (disk-buffer) is available only in the Premium Edition.
Only the Premium Edition can store messages in encrypted and timestamped log files (so called logstore).
The Premium Edition automatically detects configuration changes.
Only the Premium Edition can read messages from file sources that have wildcards in their path or filename.
Only the Premium Edition can handle directories recursively: that is, monitor a directory and its subdirectory for log files.
The Open Source Edition does not require a license file.
The syslog-ng Agent for IBM System i is a commercial product independent from both syslog-ng OSE and PE, and must be licensed separately.
