What to do when an External Script does not work?

When a script runs fine interactively but fails in the rsyslog context (i.e., when executed by a background process or as part of a service) it typically indicates differences between the interactive environment and the service environment. Most importantly, it is not rsyslog itself you need to look at. Check the system config and debug your script so that you can obtain maximum information on why and when it fails.

If you know exactly that rsyslog cannot start the script, check that it has sufficient permissions and that all pathes are correct (use absolute pathes!).

Besides that general advice, here are some common reasons why the problem can happen and suggestions for debugging:

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.

With current state of technology, AI can not auto-generate complete documentations. It needs to form a team with a human instead. (Image: Rainer Gerhards via AI)

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.
