CProfiles

The CProfiles provides a simple API to create and manage profiles for monitoring and observability purposes, the internal data structure is based on OpenTelemetry Profiles schema (v1/development):

Build

Clone the repository:

git clone https://github.com/fluent/cprofiles

Get into the project directory and retrieve submodules:

cd cprofiles/
git submodule update --init --recursive --remote

Compile:

cd build/
cmake -DCPROF_DEV=on ../
make

CPROF_DEV flag enables debugging mode, examples and the unit tests

Usage

For now you can try out the unit test that compiles when dev mode is enabled: tests/cprof-test-profile:

--- profile debug
Profile Duration: 0 nanoseconds
