influx-cpp

Modern C++ library for InfluxDB v2

Example

influx::Influx db("http://localhost:8086", org_id, auth_token);
influx::Bucket bucket = db.CreateBucket("MyDataBucket", 24h);

bucket << (influx::Measurement("cpu") << influx::Field("user", 90.0) << influx::Tag("node", node));
bucket.Flush();

Integration

This library is currently designed to be integrated with projects using CMake and Conan (however, it is not yet available as a Conan package itself). Include it using add_subdirectory. You will need to add the following to your project's conanfile.txt:

• libcurl/7.79.Z
• nlohmann_json/3.10.Z
• gtest/1.11.Z

Known issues and limitations

• On MSVC influx::Timestamp are in hundreds of nanoseconds, not nanoseconds, due to MSVC's implementation of system_clock.
• Flux query parsing is very limited and only supports predictable measurement querying. If you do complex query use QueryRaw to get raw output. I intend to fix this in the future.
• All communications with the InfluxDB instance are blocking. Threading concerns are left to the implementor.
