From ETW to EventPipe

on YouTube ↗01h 02m

" summary

Performance counters disappear on .NET Core, so the talk shows replacing them with CLR events captured via ETW on Windows and EventPipe cross‑platform; demos collect 10 and 5 thrown exceptions with PerfView, then use dotnet‑trace to produce .nettrace files. TraceEvent NuGet parses payloads; sample profiler suspends threads every millisecond (expensive). Examples show computing contention and GC pause durations from paired timestamps, GC allocation tick fires every 100KB, and custom counters (via dotnet‑counters or TraceEvent NuGet) and an in‑proc EventListener work — used at Criteo on tens of thousands of servers.
