Caution:

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.

Caution:

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 details about the syslog-ng Agent for Windows application, see the syslog-ng Agent for Windows documentation. For an agent-less solution, see the list of supported platforms.

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.

New features in syslog-ng PE 7.0.20

Version 7.0.20 of syslog-ng PE includes the following main features.

  • Red Hat EL 8 support

    Starting with version 7.0.20, syslog-ng PE supports Red Hat EL 8 (kernel version 4.18).

  • SNMP destination

    The snmp() destination of syslog-ng PE can send log messages to an SNMP destination.

  • The syslog-ng PE application uses its own Python interpreter

    Starting from version 7.0.20, the syslog-ng PE application uses its own Python interpreter (shipped with the default syslog-ng PE installation) instead of the system's Python interpreter.

    NOTE: The syslog-ng PE application's built-in Python interpreter only supports Python 3. As a result, any custom Python code used in syslog-ng PE must be compatible with Python 3.

  • Disabling and forcing TLSv1.3 in TLS contexts
    • The tlsv1_3 value has been added to the available values of ssl-version() for drivers based on the http() destination.

    • The no-tlsv13 value has been added to the available values of ssl-options() in TLS contexts.

  • New statistics item: the connections counter

    The connections counter of syslog-ng PE displays the number of active connections for network-based sources in the syslog-ng-ctl stats statistics information.
