"Observability is the capability to continuously generate and discover actionable insights based on signals from the system under observation with the goal to influence that system" and that's for both people (eg debugging) and automation (eg autoscaling) @mhausenblas #QConLondon 
Observability can go beyond usual metrics, logs and traces: @mhausenblas introducing profiles and eBPF #QConLondon
High-level architecture of Continuous Profiling, from agent and ingestion to frontend for visualisation. @mhausenblas #QConLondon
Continuous Profiling with Parca, open source project, with concepts and query language very close to Prometheus. @mhausenblas #QConLondon
Looking ahead, eBPF is becoming the unified collection method for profiles. Profiling standards seem to be converging towards pprof with its increasing support @mhausenblas #QConLondon
Correlation remains a challenge with profiles, to link together all the different signal types, rather than dealing with multiple independent tools. @mhausenblas #QConLondon
