ControlTheory Blog

ControlTheory is headed to KubeCon + CloudNativeCon Europe 2025 – April 1-4, 2025 in London. Stop by booth S732 to check out how we are helping organizations regain control of their observability. Learn how to cut costs and optimize outcomes without changing your existing tools – including Datadog, Grafana, AWS CloudWatch, Dynatrace, NewRelic, or Cribl. […]

As I made my annual pilgrimage to KubeCon (US) this year, I started to think about my work over the year with OpenTelemetry (OTel), as well as KubeCon’s past and my perspective on where things are at. This perspective has been informed by my own tinkering certainly, but also conversations with many customers over the […]

Last Friday brought about the close of another KubeCon. And in other news last week, we had snow! Though it was less startling than the snow in KubeCon Austin in 2017, it seemed like a reminder from KubeCon’s past to not forget from whence we came – and to take stock of what’s changed, what’s […]

First there was monitoring. And logging. Then came traces. And let’s add RUM and profiling into that mix, too. Oh yeah, don’t forget APM. That’s a lot of signals, and I’m sure I missed a few. Along the way though, “Observability” was born. It first appeared in this new context in print in a Twitter […]

“Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs. In control theory, the observability and controllability of a linear system are mathematical duals.”

It’s time. Time to consider what’s next for Observability. Time to consider how to introduce more OpenTelemetry into your infrastructure. KubeCon is the perfect time to open your mind, question your current investments and preconceptions, and prepare for the BIG changes on the horizon.
