Certain sources and destinations are not supported on every platform (particularly, the sql() destination, and the hdfs() destination). For details, see the description of the specific source and destination.
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.
HTTPS connection, as well as password- and certificate-based authentication is supported. The content of the events is sent in JSON format.
Version 7.0.12 of syslog-ng PE is now available on the Ubuntu 18.04 platform. Note that the Java-based drivers of syslog-ng PE (used for Apache Kafka, Elasticsearch, HDFS) require Java 8, Java 10 is not supported.
The http() destination now supports load balancing, so a single syslog-ng PE instance can feed log data to multiple HTTP servers, for example, multiple ingestion nodes of an Elasticsearch cluster. For details, see "Batch mode and load balancing" in the Administration Guide.
HTTP and HTTPS redirections now also handled automatically.
The syslog() and network() drivers now support the so-reuseport() option that allows multiple sockets on the same host to bind to the same port, improving the performance of multithreaded network server applications running on top of multicore systems.
The Cisco parser now supports Cisco Catalyst formatted triplets.
