traceable-agent 1.0.4

Traceable.ai Python Agent

Python Agent

Usage

Python traceable agent requires Python >= 3.6

Additionally, to use the traceable filter, you must be on a supported OS.

• Ubuntu 18.04+
• Centos 7+
• Debian 10+
• Amazon Linux 2+

Instrumentation methods

There are two ways to instrument your application, auto-instrumentation and code based instrumentation.

Autoinstrumentation

Simply prepend traceableai-instrument to your applications startup command.

ex: traceableai-instrument flask run

Code based instrumentation

Add the following snippet to your python apps entrypoint file:

from traceableai.agent import Agent

app = Flask(__name__)

agent = Agent()
agent.instrument(app) # This will instrument the flask app + any other modules that are supported
agent.add_traceable_filter() # add the traceable filter to enable blocking

Developing

# Create a virtual env & install dependencies
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt -r dev-requirements 

Note: if you run into an error installing grpc:

File "/Users/user/.pyenv/versions/3.9.4/lib/python3.9/distutils/unixccompiler.py", line 120, in _compile raise CompileError(msg) distutils.errors.CompileError: command '/usr/bin/clang' failed with exit code 1

prepend this env var to the above pip install command: GRPC_PYTHON_BUILD_SYSTEM_ZLIB=true

Building

pip install -r requirements.txt
python3 -m build

Instrumenting

traceableai-instrument your_startup_command
# ex: traceableai-instrument flask run -p 5000 

Updating Libtraceable

When you want to update libtraceable you should first download the latest version and precompile the headers. gcc -E blocking.h > blocking.h.preprocessed

Then mv blocking.h.preprocessed ./src/traceableai/filter/blocking.h.preprocessed

Additionally, open src/download.py Edit the constant: LIBTRACEABLE_VERSION set it equal to the version you just generated headers for.

You can test this functionality by using the project within the: docker/test_apps It will fail to build if libtraceable cannot be downloaded

Updating the Proto

git submodule update --init --recursive
./scripts/build_proto.sh

Unit Tests

build_artifacts.sh builds all the whl files. Specify skipped versions in (CIBW_SKIP) to only build 3.6 for unit tests.

CIBW_SKIP="*37* *38* *39* *310*" ./build_artifacts.sh
docker build --build-arg ARTIFACTORY_USER --build-arg ARTIFACTORY_TOKEN -f docker/test_apps/Dockerfile.unittest -t pythonunittest . && docker run --rm pythonunittest

Test applications

Refer to docker/test_apps/ and the corresponding scripts in scripts/
