Syslog-ng Python Packaging
In version 4 of syslog-ng, the role of Python became even more important. Previously, all parts of syslog-ng could be extended using Python code, but no actual Python code was provided with syslog-ng. Version 4.0 added a Kubernetes module implemented in Python, while version 4.2 added support for Hypr. But how can we ensure that all Python dependencies are met? In my latest blog I describe the current situation and ask you for feedback!

Getting syslog-ng 4
Version 4 of syslog-ng was released last December. Quite a few people use it already in production. How can you install it for a test drive? It might be already available in your Linux distribution. There are also several unofficial repositories with the latest syslog-ng. From this blog, you can learn how to check your syslog-ng version, where to check if it is not yet installed, and a few additional resources, if you want to install the latest version from unofficial repositories.
Upgrade problems from syslog-ng 3 to 4
Version 4 of syslog-ng works perfectly well in version 3 compatibility mode. However, if you want to use the syslog-ng 4 features, you need to be aware of some significant changes. If you have a simple configuration, like those in Linux distributions, then simply rewriting the version string is most likely enough. However, if you use PatternDB or JSON parsing, any Python code, or an Elasticsearch, or MongoDB destination, you have to be aware of the changes.
The syslog-ng Insider 2023-04: FreeBSD; Splunk; Deduplication;
The April syslog-ng newsletter is now on-line: Installing a syslog-ng 4 development snapshot on FreeBSD Getting data to Splunk Streaming deduplication in syslog-ng It is available at https://www.syslog-ng.com/community/b/blog/posts/the-syslog-ng-insider-2023-04-freebsd-splunk-deduplication syslog-ng logo
Getting data to Splunk
Getting data to Splunk can be challenging. Syslog is still the most important data source, and it can provide you with hard-to-solve problems (for example, like high volume, non-compliant messages, unreliable network protocol (UDP), and more). The syslog-ng Premium Edition (PE) and syslog-ng Store Box (SSB) by One Identity can make these challenges manageable. https://www.syslog-ng.com/community/b/blog/posts/getting-data-to-splunk syslog-ng logo
Syslog-ng 101, part 13: Updating syslog-ng, syslog-ng 4
Version 4 of syslog-ng is now available. The good news is that it is fully backwards compatible. If the version string in your configuration is set to a 3.X version, it will work as expected even after updating to version 4. Of course you might run into corner cases, but I had no problems even with complex configurations. Today, we learn about updating syslog-ng, and some of the new features of syslog-ng 4.
Syslog-ng 101, part 12: Elasticsearch (and Opensearch, Zinc, Humio, etc.)
