The observability landscape is witnessing a radical transformation today. The central driver of this shift is eBPF (extended Berkeley Packet Filter), a technology that is revolutionizing how we observe and monitor systems. In an earlier post, we took a detailed look at the technology of eBPF and its implications for observability.
In this article, we will compare eBPF-based instrumentation with other instrumentation methods like code agents and sidecars and see which best suits the needs of observability today.
Before we dive in, let’s briefly revisit eBPF.
