Instrumentation Tools & Auto Instrumentation for OpenTelemetry Python

Installation

pip install opentelemetry-instrumentation

This package provides commands that help automatically instrument a program:

Note

You need to install a distro package to get auto instrumentation working. The opentelemetry-distro package contains the default distro and configurator and automatically configures some of the common options for users. For more info about opentelemetry-distro check here

pip install "opentelemetry-distro[otlp]"

When creating a custom distro and/or configurator, be sure to add entry points for each under opentelemetry_distro and opentelemetry_configurator respectfully. If you have entry points for multiple distros or configurators present in your environment, you should specify the entry point name of the distro and configurator you want to be used via the OTEL_PYTHON_DISTRO and OTEL_PYTHON_CONFIGURATOR environment variables.

opentelemetry-bootstrap

opentelemetry-bootstrap [-a |--action=][install|requirements]

This command install default instrumentation packages and detects active Python site-packages to figure out which instrumentation packages the user might want to install. By default, it prints out a list of the default and detected instrumentation packages that can be added to a requirements.txt file. It also supports installing the packages when run with --action=install or -a install flag. All default and detectable instrumentation packages are defined here <https://github.com/open-telemetry/opentelemetry-python-contrib/blob/main/opentelemetry-instrumentation/src/opentelemetry/instrumentation/bootstrap_gen.py>.

opentelemetry-instrument

opentelemetry-instrument python program.py

The instrument command will try to automatically detect packages used by your python program and when possible, apply automatic tracing instrumentation on them. This means your program will get automatic distributed tracing without having to make any code changes. This will also configure a global tracer and tracing exporter as well as a meter and meter exporter. By default, the instrument command will use the OTLP exporter but this can be overridden.

The command supports the following configuration options as CLI arguments and environment variables:

• --traces_exporter or OTEL_TRACES_EXPORTER

• --metrics_exporter or OTEL_METRICS_EXPORTER

• --distro or OTEL_PYTHON_DISTRO

• --configurator or OTEL_PYTHON_CONFIGURATOR

The exporter options define what exporter destination to use and can be set to one or more exporter names (see below). You can pass multiple values to configure multiple exporters (e.g., zipkin_json,otlp).

• Defaults to otlp.

• Can be set to none to disable automatic tracer initialization.

• Can be set to ‘console` to display JSON results locally.

Trace exporter names:

• jaeger_proto

• jaeger_thrift

• opencensus

• otlp

• otlp_proto_grpc (deprecated)

• otlp_proto_http (deprecated)

• zipkin_json

• zipkin_proto

Metric exporter names:

• otlp

• otlp_proto_grpc (deprecated)

• prometheus

Note: The default transport protocol for otlp is gRPC.

• --id-generator or OTEL_PYTHON_ID_GENERATOR

Used to specify which IDs Generator to use for the global Tracer Provider. By default, it will use the random IDs generator.

The code in program.py needs to use one of the packages for which there is an OpenTelemetry integration. For a list of the available integrations please check here

• OTEL_PYTHON_DISABLED_INSTRUMENTATIONS

If set by the user, opentelemetry-instrument will read this environment variable to disable specific instrumentations. e.g OTEL_PYTHON_DISABLED_INSTRUMENTATIONS = “requests,django”

Examples

opentelemetry-instrument --traces_exporter console flask run --port=3000

The above command will pass --traces_exporter console to the instrument command and --port=3000 to flask run.

opentelemetry-instrument --traces_exporter zipkin_json,otlp celery -A tasks worker --loglevel=info

The above command will configure global trace provider, attach zipkin and otlp exporters to it and then start celery with the rest of the arguments.

opentelemetry-instrument --id_generator random flask run --port=3000

The above command will configure the global trace provider to use the Random IDs Generator, and then pass --port=3000 to flask run.

Programmatic Auto-instrumentation

from opentelemetry.instrumentation import auto_instrumentation
auto_instrumentation.initialize()

If you are in an environment where you cannot use opentelemetry-instrument to inject auto-instrumentation you can do so programmatically with the code above. Please note that some instrumentations may require the initialize() method to be called before the library they instrument is imported.
