eBPF tracing is a broad and deep subject, and can be a bit daunting at first sight. However, when Brendan Gregg issued the dictum “Perhaps you’d like a new year’s resolution: learn eBPF!”, I figured it was as good a time as any to do something fun with it. Here at Circonus, we’ve talked about eBPF previously, so I had a starting point to look for an interesting problem to solve.
