Windows logs provide a wealth of information that must be made usable for Observability. As you may know, I work on normalizing these logs for quite some while, I even created liblognorm for that purpose. Ingesting them properly is important for schema mapping, e.g. to Elastic Cloud.

I am glad to tell that I finally managed to solve an issue that caused confusion for years. Someone had cloned and published the rsyslog documentation at readthedocs. Unfortunately, it was not maintained afterwards and also looked like an official rsyslog doc. That added a lot to the “rsyslog’s doc is bad and inconsistent” feel inside the community. This could now be resolved, and current, official doc is now available at readthedocs. I am very happy and glad for readthedocs staff members who helped us to finally resolve the issue.
Status update: omhttp, CI, backlog, and containers
Time goes fast, it is Sep 10 already. Mid August I said we will do a great refactoring of omhttp within a week or two. Well, that did not work out as planned. We still made solid progress, but more pressing work put it on hold for a bit. Time for a small update of what is happening in rsyslog.
rsyslog becoming target for social engineering PRs? Lessons learned.
In the past days I noticed PR patterns that do not look right. This is a smell, not a verdict. The upside is real: rsyslog is interesting enough to attract attention. That is actually great news. Now we have the problem ourselves, and that is the moment to engineer the right guardrails without losing our welcoming tone. You need to be a target in order to gain sufficient experience to tackle that hard problem.
Sluggish Responses – And How We Plan to Do Better
TL;DR
- My responses to PRs and issues were sluggish, especially during the pandemic. I am sorry, and thank you for sticking with us.
- We aim for reasonable, not instant, turnaround.
- Expect a quick maintainer look at every PR within 3 business days.
- Full review typically follows once CI is green and AI review items are addressed or explained.
- We will not mass-close old issues. We are revisiting them with AI assist and closing for the right reasons.
- We are formalizing labels and dashboards to make navigation easier. Details will follow in a short, separate post.
- Suggestions are welcome.
I want to be very honest with you: my responses to pull requests and issues have been sluggish for quite some time. This affected the whole rsyslog project, because in the end it always comes back to the limited capacity of the maintainers – and most often, that means me.
We are working hard to change this. It will not mean ultra-fast turnaround times, but it will mean reasonable turnaround times. We have already made important steps, and AI will play a key role in improving this going forward. Still, this is work in progress, and I welcome your suggestions.

Seventeen years old, raw “armchair philosophy” — but surprisingly close to what I still believe today.
While reflecting on my current work, I remembered a text I had written in April 2008 during a discussion with a friend in biology. It’s an unfinished “armchair philosophy” piece — raw, dense, and hard to read — but it still reflects many of my core beliefs about IT systems. I’m publishing it unchanged as an archival entry, because the foundations it sketches are still relevant today.

I’ve long had mixed feelings about messengers – especially WhatsApp—because of privacy concerns. At the same time, as a councilman in my village, WhatsApp is essentially unavoidable in Germany. Announcements, e.g. from Public bodies and personal conversations – much of the day-to-day information flow runs through it. So I use it in that local role and follow announcement channels from government institutions. It also the tool to go for one-on-one conversations with my fellow citizens.
(Side note: for genuinely private conversations with security-aware folks, I prefer Threema. I’m well aware of the privacy trade-offs.)

I chased a rare crash in highly-threaded code. It popped up now and then; earlier fixes didn’t stick. I suspected an advanced concurrency issue. I also asked Gemini, Copilot/Codex, and Claude for help. They agreed with me: surely something subtle—epoll, re-queueing, ownership flags…
We were all wrong—and, importantly, I was wrong in the same way the AIs were. Their analyses reinforced my initial hypothesis. The fact that the static analyzer reported nothing reinforced it even more—after all, that’s “proven non-AI tech.” In hindsight, if I had thought earlier about the limits of these tools (AI and non-AI), I might have changed direction sooner—but I was also primed by experience: in this part of the codebase, bugs are almost always complex.

I’ve been using AI to help with commit messages for a while now. Yesterday, in a discussion with co-workers, it became clear that this may not just be a convenience feature — it’s turning into a real time saver.
That was the background for creating the new rsyslog Commit AI Assistant. It directly addresses a problem we ourselves face in daily development. True to dogfooding, we now use it internally whenever we craft a commit message — myself included.
Want to give it a try: use the rsyslog commit Assistant.

This week—and likely into next—my primary focus (together with Andre and our AI Agents) is a substantial refactor of contrib/omhttp. We’re tracking the work in #5957 and will link the PR from there once it’s open.
