Did you know we're now in the third generation of observability solutions? Over 20 years ago, I envisioned the future of observability with Application Performance Management (APM) - see my description of the imaginary JFantasticAPM in that article! We're not quite where I envisioned yet, even with the current third generation. But the recent LLM developments in AI have moved us to within sight of what I envisaged - the fourth generation solutions.

What I envisioned 20 years ago should become available within the next 5 years. To update that vision and see where we are, I've written a new article that covers the past, present and future of observability. It's especially interesting if you're not aware of the agentic capability already available in Observability and APM solutions.

Now on to all the usual newsletter list of links, tips, tools, news and talks, and as usual I've extracted all the tips into this month's tips page.
