Lumigo OpenTelemetry Distribution for Python
Project description
Lumigo OpenTelemetry Distro for Python :stars:
The Lumigo OpenTelemetry Distribution for Python is a package that provides no-code distributed tracing for containerized applications.
The Lumigo OpenTelemetry Distribution for Python is made of several upstream OpenTelemetry packages, with additional automated quality-assurance and customizations that optimize for no-code injection, meaning that you should need to update exactly zero lines of code in your application in order to make use of the Lumigo OpenTelemetry Distribution. (See the No-code instrumentation section for auto-instrumentation instructions)
Note: If you are looking for the Lumigo Python tracer for AWS Lambda functions, lumigo-tracer
is the package you should use instead.
Supported Runtimes
- cpython: 3.7.x, 3.8.x, 3.9.x, 3.10.x
Setup
Add lumigo_opentelemetry as dependency
The lumigo_opentelemetry
package needs to be a dependency of your application.
In most cases, you will add lumigo_opentelemetry
as a line in requirements.txt
:
lumigo_opentelemetry
Or, you may use pip
:
pip install lumigo_opentelemetry
Environment-based configuration
Configure the LUMIGO_TRACER_TOKEN
environment variable with the token value generated for you by the Lumigo platform, under Settings --> Tracing --> Manual tracing
:
# Replace `<token>` below with the token generated for you by the Lumigo platform
export LUMIGO_TRACER_TOKEN=<token>
It is also strongly suggested that you set the OTEL_SERVICE_NAME
environment variable with, as value, the service name you have chosen for your application:
# Replace `<service name> with the desired name of the service`
export OTEL_SERVICE_NAME=<service name>
Tracer activation
There are two ways to activate the lumigo_opentelemetry
package: one based on importing the package in code (manual activation), and the other via the environment (no-code activation).
The no-code activation approach is the preferred one.
No-code activation
Note: The instructions in this section are mutually exclusive with those provided in the Manual instrumentation section.
Set the following environment variable:
export AUTOWRAPT_BOOTSTRAP=lumigo_opentelemetry
Manual activation
Note: The instructions in this section are mutually exclusive with those provided in the No-code activation section.
Import lumigo_opentelemetry
at the beginning of your main file:
import lumigo_opentelemetry
Configuration
OpenTelemetry configurations
The Lumigo OpenTelemetry Distro for Python is made of several upstream OpenTelemetry packages, together with additional logic and, as such, the environment varoables that work with "vanilla" OpenTelemetry work also with the Lumigo OpenTelemetry Distro for Python. Specifically supported are:
- General configurations
- Batch span processor configurations: The Lumigo OpenTelemetry Distro for Python uses a batch processor for sending data to Lumigo.
Lumigo-specific configurations
The lumigo_opentelemetry
package additionally supports the following configuration options as environment variables:
LUMIGO_TRACER_TOKEN
: [Required] Required configuration to send data to Lumigo; you will find the right value in Lumigo underSettings -> Tracing -> Manual tracing
.LUMIGO_DEBUG=TRUE
: Enables debug loggingLUMIGO_DEBUG_SPANDUMP
: path to a local file where to write a local copy of the spans that will be sent to Lumigo; this option handy for local testing but should not be used in production unless you are instructed to do so by Lumigo support.LUMIGO_SECRET_MASKING_REGEX=["regex1", "regex2"]
: Prevents Lumigo from sending keys that match the supplied regular expressions. All regular expressions are case-insensitive. By default, Lumigo applies the following regular expressions:[".*pass.*", ".*key.*", ".*secret.*", ".*credential.*", ".*passphrase.*"]
.LUMIGO_SWITCH_OFF=TRUE
: This option disables the Lumigo OpenTelemetry distro entirely; no instrumentation will be injected, no tracing data will be collected.
Baseline setup
The Lumigo OpenTelemetry Distro will automatically create the following OpenTelemetry constructs provided to a TraceProvider
:
- A
Resource
built from the default OpenTelemetry resource with thesdk...
attributes - If the
LUMIGO_TRACER_TOKEN
environment variable is set: a BatchSpanProcessor, which uses anOTLPSpanExporter
to push tracing data to Lumigo - If the
LUMIGO_DEBUG_SPANDUMP
environment variable is set: aSimpleSpanProcessor
, which uses anConsoleSpanExporter
to save to file the spans collected. Do not use this in production!
