Documentation Improvement and AI

For a long time, I struggled with the daunting task of enhancing the documentation for Rsyslog. My extensive knowledge of Rsyslog technology often made it challenging for me to create user-friendly documentation, especially for individuals with little to no syslog background. Additionally, as a non-native English speaker, I was aware that some of my sentences might be harder to understand than desired. But thanks to the breakthroughs in generative artificial intelligence (AI), the game has changed, and a new era of documentation improvement has begun.

Elevating Syslog Security: RSyslog Introduces DTLS Plugins for UDP

We at the RSyslog project are excited to share our recent advancements in syslog security. We have introduced initial plugins for Datagram Transport Layer Security (DTLS) syslog, namely imdtls (input module) and omdtls (output module). This development, which aligns with RFC 6012, represents a significant enhancement, albeit not a game-changer, in our continuous efforts to improve secure log transmission.

Release Date: 2023-06-21

Build-IDs: Service 7.4.0.223, Client 7.4.0.315

Bugfixes

  • Syslog Action: Fixed a very rare case where an Action could try to open **TCP connections** to the same target **multiple times simultaneously**. The handling has been hardened to avoid concurrent connection establishment retries for the same Action.
  • Syslog Action: Fixed error handling when **the** connection fails and Syslog Caching is enabled. If a syslog backup server is enabled, the action will now retry the primary server correctly again after syslog caching has been activated.
  • EventLog Monitor V2: Fixed an issue in XML-Stream Processing that could cause failure in processing an EventLog Message.
  • LogRotate: Corrected error reporting when the feature is not available **due to** licensing.
  • Network Core: **Enhanced stability** during closing connections.

RSyslog Windows Agent 7.4 Released

Adiscon is proud to announce the 7.4 release of Rsyslog Windows Agent.

This latest release delivers enhanced stability and improved error handling, reflecting our commitment to offering our customers the most secure and efficient solutions. Key updates include vital improvements to our Syslog Action functionality. Our engineers have resolved a rare situation where an Action might have attempted to establish multiple TCP connections with the same target simultaneously. Also, in the event of a connection failure, error handling has been improved to retry the primary server correctly if a Syslog backup server is active and Syslog caching has been activated.

We have also made significant advancements in our EventLog Monitor V2 by fixing an XML-Stream processing issue that could impede processing an EventLog message. Changes in our Network Core further amplify system stability during connection closures.

Finally, we’ve enhanced our LogRotate functionality, improving error reporting for situations where the feature is unavailable due to licensing limitations. As always, Adiscon remains committed to providing superior system reliability, robust security, and exemplary customer support. Stay tuned for more updates on our continuing development.
