Netflix Launches bpftop Aimed at Enhancing eBPF Performance Efficiency
Netflix has recently announced bpftop, a command-line utility aimed at enhancing the optimization and monitoring of eBPF programs. bpftop provides a real-time snapshot of eBPF programs in operation. It shows metrics such as the average duration of program execution, the number of events processed every second, and an approximation of the total CPU usage percentage for each program.

Grafana Beyla Provides Auto-Instrumented Observability through eBPF
Grafana has released Grafana Beyla, an open-source eBPF auto-instrumentation tool for application observability. Beyla is able to report span information and RED metrics (Rate-Errors-Duration) for both Linux HTTP/S and gRPC services. This is accomplished without having to make code modifications for inserting probes.
