pprof
pprof is a tool for visualization and analysis of profiling data.
pprof reads a collection of profiling samples in profile.proto format and
generates reports to visualize and help analyze the data. It can generate both
text and graphical reports (through the use of the dot visualization package).
profile.proto is a protocol buffer that describes a set of callstacks
and symbolization information. A common usage is to represent a set of
sampled callstacks from statistical profiling. The format is
described on the proto/profile.proto file. For details on protocol
buffers, see https://developers.google.com/protocol-buffers
Profiles can be read from a local file, or over http. Multiple
profiles of the same type can be aggregated or compared.
If the profile samples contain machine addresses, pprof can symbolize
them through the use of the native binutils tools (addr2line and nm).
