If you are planning to use Python in syslog-ng PE (for example Python parser or Python template function) on RHEL 6 platform, then you have to manually install Python 2.7. If the Python version on the machine is not 2.7, you will receive a similar error message during startup:
[2017-07-27T13:42:03.606679] Reading shared object for a candidate module: path='/opt/syslog-ng/lib/syslog-ng', fname='mod-python.so', module='mod-python' [2017-07-27T13:42:03.606994] Error opening plugin module: module='mod-python', error='libpython2.7.so.1.0: cannot open shared object file: No such file or directory'
For using syslog-ng PE on other platforms (for example, AIX, FreeBSD, HP-UX, Solaris, Microsoft Windows), see the list of supported platforms in the syslog-ng PE version 6 Administration Guide.
The stackdriver destination of syslog-ng PE can send log messages to the Google Stackdriver cloud. Google Stackdriver is a widely used metrics, event, and log aggregator and analyzer system. For details, see "stackdriver: Sending logs to the Google Stackdriver cloud" in the Administration Guide.
The Windows Event Collector application now supports Windows Server 2019.
The syslog-ng-ctl reload command now has a return value: 0 if the operation was successful, 1 otherwise.
Instead of dropping incoming messages that are too long, you can now trim them using the trim-large-messages() option of the syslog() source.
