Instructions Retired Explorer is a tool to parse ETW files like those produced by BenchmarkDotNet (aka BDN) (via -p ETW) or PerfView.
It understands profile, jit, and method events, and can attribute profile or PMU samples to jitted code.
It also understands BDN's profiling events, and can filter profiles to just those taken when BDN is actively measuring performance (that is, it will ignore the various warmup and overhead phases, as well as time spent within BDN itself).
dotnet run -- file.etl [-process process-name] [-pid pid] [-show-events] [-show-jit-times] [-benchmark] [-instructions-retired]
-process: defaults to corerun
-pid: choose process to summarize via ID
-benchmark: only count samples made during BechmarkDotNet intervals. Changes default process to dotnet
-show-events: show counts of raw ETL events
-show-jit-times: summarize data on time spent jitting
-show-samples <pattern>: show raw method-relative hits for some methods
-instructions-retired: if ETL has instructions retired events, summarize those instead of profile samples
This shows some output from analyzing a BDN produced file, with -benchmark:
