v0.1.2 -Minor Release

What's Changed

• pprof: add support for allocations and lock data by @dpsoft in #18

GO(mode): Allocs & Block Support

The AP-Agent now supports two additional endpoints in Go mode, allowing you to profile memory allocations and contended locks.

/debug/pprof/allocs endpoint, you can get a profiling report of memory allocations performed by the application.
/debug/pprof/block endpoint returns a profiling report of contended locks that are blocking on synchronization primitives.

All the credits to @NeQuissimus for the changes to support allocations and lock data(async-profiler/async-profiler#713) in async-profiler converter.

v0.1.0 - First Release

Startup Banner

The banner currently only shows the current version of the agent and the AP-Loader

Hot/Cold FlameGraph Support(Mixed)

This type of visualization combines both on-CPU and off-CPU flame graphs. This visualization provides a comprehensive view of the performance data by showing all thread time in one graph and allowing direct comparisons between on-CPU and off-CPU code path durations. The hot and cold functions are shown together in the same graph, providing a clear and concise view of the performance of the program.

The darker colors indicate on-CPU and lighter colors indicate off-CPU

hotcold (http://localhost:8080/profiler/profile?event=wall&output=hotcold&duration=30)

Firefox Profiler Support

Basic example with curl

1. Execute the profiler for the cpu event, fp (Firefox Profiler) output, a 60 seconds duration and write the response to profiling_results/firefox-profiler-example.json.gz

curl -s "http://localhost:8080/profiler/profile?event=cpu&output=fp&duration=60" -o profiling_results/firefox-profiler-example.json.gz

2. Visit the Firefox Profiler page

3. Load the output file from step 1, and you'll see the profiling result
