%description
Wprof is a low-overhead BPF-based tracer and profiler with the focus on holistic
system-level performance data capture and analysis. It employs powerful and
flexible model of split data capture vs analysis/visualization phases, which
allows to iterate on captured performance data with exactly the same original
data. Wprof generates Perfetto-based traces and provides many options for
filtering and narrowing down exact subset of data to be visualized.
