Profiles, the Missing Pillar: Continuous Profiling in Practice

With Continuous Profiling (CP) you capture resource usage (such as CPU, memory, I/O, etc.) over time, enabling you to pinpoint the (source) code that is slow or causes an issue. In recent times, CP has become mainstream and a number of open source projects such as Parca, Pyroscope, or CNCF Pixie are now available to benefit from CP in your own environment. We will have a look at the origins and the underlying motivation of CP and discuss cost and benefits of using CP in production. Finally, we will make the case that profiles are, in addition to logs, metrics, and traces, the missing pillar of observability.

Could Observability-Driven Development Be the Next Leap?

Tuesday Apr 5 / 04:10PM BST

Twenty years ago Kent Beck coined the term “test-driven development”: write tests first, develop the code later. Today, even if not practising true TDD, the idea of writing code without tests is an immediate warning sign to any developer. Yet, most teams still continue shipping code...

Slack’s DNSSEC Rollout: Third Time’s the Outage

Tuesday Apr 5 / 02:55PM BST

We all have to manage DNS. DNS changes are inherently high-blast-radius and high-visibility. We present a case study of what happened when a large SaaS company enabled DNSSEC. We did significant planning and testing beforehand. The rollout went smoothly for most of our domains, but one...

An Observable Service with No Logs

Tuesday Apr 5 / 10:35AM BST

After working with Honeycomb for a little while and starting to instrument our existing code with events, I’d become enamoured with the level of observability possible with that sort of telemetry. In particular, how easy it became to interactively and visually explore how my systems were...

Chaos Engineering Observability with Visual Metaphors

Tuesday Apr 5 / 01:40PM BST

Observability is key in operating a system in production; it’s required during an incident, when an operator has to interrogate, inspect, and piece together what happened to avoid a similar event. In those scenarios, Chaos engineering and Observability are closely connected - providing...
