Dear syslog-ng users,

This is the 71st issue of syslog-ng Insider, a monthly newsletter that
brings you syslog-ng-related news.

NEWS

Version 3.19 of syslog-ng released
----------------------------------

Version 3.19 of syslog-ng has been released with plenty of new
features and bugfixes. Performance of the HTTP destination improved
thanks to load-balancing to multiple servers. You can use this to send
the messages to a set of ingestion nodes or indexers of your SIEM
solution if a single node cannot handle the load. The new Slack
destination allows you to send alerts to a Slack channel.

https://github.com/balabit/syslog-ng/releases/tag/syslog-ng-3.19.1.


Optimize your Splunk infrastructure using new syslog-ng features
-------------------------------------------------------

Learn how to use less resources for better performance in Splunk! Many
people have been using syslog-ng for decades without knowing that it
receives new features as well as bugfixes. While many Linux utilities
are practically in maintenance mode, syslog-ng keeps evolving
constantly. A strong focus in recent years has been on message parsing
and destination drivers.

After my talk at Suricon, Splunk users explained how they will change
their syslog-ng configurations to optimize their Splunk
infrastructure.

Python source in syslog-ng
--------------------------

Using syslog-ng 3.18 and newer releases, you can write new source
drivers for syslog-ng in Python. While performance is not as good as
C, you gain flexibility and ease of implementation. There are quite a
few log sources without a ready to use C API, but with a Python API.
Using the Python source of syslog-ng you can leverage these.

Bulk mode message sending to Elasticsearch with syslog-ng http() destination
---------------------------------------------------------

Learn how to send log messages in bulk mode to your Elasticsearch
server with syslog-ng. Bulk mode offers better performance, because it
sends multiple log messages in a single POST request.
