OpenTelemetry in Python Applications

Effective document generation and observability are essential foundations for developing scalable and resilient systems in contemporary software development. Developers can instrument, gather, and analyze observable data from distributed systems using OpenTelemetry, an open-source observability platform.

Developers can easily create, modify, and output PDF documents with IronPDF, a robust .NET framework. This article will discuss the integration of OpenTelemetry Python with IronPDF, demonstrating how these two technologies work together to improve observability and document generation potential.

Developers can access an extensive feature set for instrumenting, gathering, and exporting open telemetry and data from distributed systems with the OpenTelemetry API and SDK packages, an OpenTelemetry project implementation in Python.

OpenTelemetry Features

Let's examine OpenTelemetry instrumentation for Python's salient features:

Distributed Tracing

• Distributed tracing, which lets developers follow the path of requests through dispersed systems, is made possible by OpenTelemetry for Python.
• Traces offer insight into the sequence of requests, including the dates and times of service contacts.
• Python programs can be instrumented by developers to record spans, which are discrete actions or parts of a distributed trace.

Metrics Gathering

• OpenTelemetry Python facilitates metrics import MeterProvider, which gathers numerical data regarding the behavior and performance of the system.
• Developers may instrument their applications to gather measurements like latency, throughput, error rates, and resource usage.
• By offering insights into usage patterns, performance trends, and system health, these metrics help in comprehending system behaviors.

Context Propagation

• Context propagation is made easier by the OpenTelemetry API package, which makes sure that distributed context—such as trace and span context—is propagated across service boundaries.
• Telemetry data can be correlated and contextualized as it moves through the system due to context propagation, which preserves the data's continuity and consistency.

Libraries of Instrumentation

• OpenTelemetry Python makes it simple to instrument existing Python applications by providing instrumentation packages for widely used frameworks, libraries, and protocols.
• Integrations for web frameworks (like Flask and Django), database clients (like SQLAlchemy and Pymongo), messaging systems (like Kafka and RabbitMQ), and more can be found in instrumentation libraries.

Ecosystem of Exporters

• A range of exporters provided by OpenTelemetry Python enables developers to export telemetry data to different observability systems and backends.
• Integrations with observability platforms like Jaeger, Zipkin, Prometheus, AWS X-Ray, Google Cloud Trace, and others are supported by exporters.
• Exporters can be set up by developers to transfer telemetry data to one or more backends for long-term storage, analysis, and display.
• Variable sampling techniques are supported by OpenTelemetry Python to regulate the quantity of telemetry data gathered.
• Developers have the option to apply custom sampling logic, set sampling to sample a certain percentage of traces, or sample according to predefined parameters (such as request headers or routes).

Contextual Recordkeeping

• Tools for recording contextual data in addition to telemetry data are available with the OpenTelemetry Python SDK.
• Developers can add trace and span context to log messages with contextual logging, which gives more context for troubleshooting and debugging.

Create and Configure OpenTelemetry Python

Set Up OpenTelemetry Configuration

To set up OpenTelemetry for your project, you can start by installing the necessary packages using pip install opentelemetry-exporter-jaeger.

pip install opentelemetry-exporter-jaeger

pip install opentelemetry-exporter-jaeger

Afterward, install the OpenTelemetry Python SDK using the following command:

pip install opentelemetry-sdk

pip install opentelemetry-sdk

The opentelemetry-api pip package provides a comprehensive API for instrumentation and offers automatic instrumentation, making it easier to instrument your applications. An alternative way of doing so could be using the export-import BatchSpanProcessor method to ensure efficient telemetry data exporting.

To define OpenTelemetry SDK parameters, create a configuration file. The configuration file otel_config.py serves as an example. Ensure all imports such as resources import Resource and trace import TracerProvider are present to set up the code example without any errors.

from opentelemetry import trace
from opentelemetry.sdk.resources import Resource
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor
from opentelemetry.exporter.jaeger.thrift import JaegerExporter

# Configure Jaeger exporter
jaeger_exporter = JaegerExporter(
    agent_host_name="localhost",
    agent_port=6831,
)

# Create a TracerProvider with Jaeger exporter
tracer_provider = TracerProvider(resource=Resource.create({'service.name': 'my-python-service'}))
tracer_provider.add_span_processor(BatchSpanProcessor(jaeger_exporter))
trace.set_tracer_provider(tracer_provider)

from opentelemetry import trace
from opentelemetry.sdk.resources import Resource
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor
from opentelemetry.exporter.jaeger.thrift import JaegerExporter

# Configure Jaeger exporter
jaeger_exporter = JaegerExporter(
    agent_host_name="localhost",
    agent_port=6831,
)

# Create a TracerProvider with Jaeger exporter
tracer_provider = TracerProvider(resource=Resource.create({'service.name': 'my-python-service'}))
tracer_provider.add_span_processor(BatchSpanProcessor(jaeger_exporter))
trace.set_tracer_provider(tracer_provider)

Within this configuration file:

• The Jaeger exporter is set up to export traces to a localhost Jaeger agent.
• Using the Jaeger exporter, we construct a TracerProvider and configure it to be the global tracer provider.
• We provide the service name for our Python program.

Initialize OpenTelemetry in Your Application

Import the otel_config module into your Python program, then initialize OpenTelemetry at the outset with the following example Python code:

from opentelemetry import trace
from otel_config import tracer_provider

# Initialize OpenTelemetry
trace.get_tracer(__name__)

from opentelemetry import trace
from otel_config import tracer_provider

# Initialize OpenTelemetry
trace.get_tracer(__name__)

By doing this, the configuration found in otel_config.py is initialized for OpenTelemetry instrumentation.

Instrument Your Application

Use OpenTelemetry to instrument your Python program so that it can record traces. You have two options for instrumenting your code: manually or via the built-in libraries. This is an illustration of a few manual instrumentation calls:

from opentelemetry import trace

# Start a span
with trace.get_tracer(__name__).start_as_current_span("example_span"):
    # Your code here
    pass

from opentelemetry import trace

# Start a span
with trace.get_tracer(__name__).start_as_current_span("example_span"):
    # Your code here
    pass

View Traces in Jaeger UI

To see and examine the recorded traces, go to the Jaeger user interface. To view the traces that the OpenTelemetry collector records, open the Jaeger UI in your web browser (usually at http://localhost:16686) and choose your service name.

You have successfully established and configured OpenTelemetry Python in your application by following these instructions. Now, you can see how your Python program behaves and performs by using OpenTelemetry to record traces and export them to the Jaeger backend.

Getting Started with IronPDF

What is IronPDF?

With the powerful .NET library IronPDF from Iron Software, developers can create, edit, and present PDF documents within .NET applications.

 pip install ironpdf

Using OpenTelemetry to Generate a PDF Document with IronPDF

Add the following code below OpenTelemetry's initialization to use IronPDF to create a PDF document:

from ironpdf import ChromePdfRenderer
from opentelemetry import trace

# Generate PDF document with IronPDF
with trace.get_tracer(__name__).start_as_current_span("pdf_generation"):
    iron_pdf = ChromePdfRenderer()
    html_content = "<html><body><h1>Hello, IronPDF!</h1></body></html>"

    pdf_content = iron_pdf.render_html_as_pdf(html_content)

    # Save or send the PDF content as needed
    with open("output.pdf", "wb") as file:
        file.write(pdf_content)

from ironpdf import ChromePdfRenderer
from opentelemetry import trace

# Generate PDF document with IronPDF
with trace.get_tracer(__name__).start_as_current_span("pdf_generation"):
    iron_pdf = ChromePdfRenderer()
    html_content = "<html><body><h1>Hello, IronPDF!</h1></body></html>"

    pdf_content = iron_pdf.render_html_as_pdf(html_content)

    # Save or send the PDF content as needed
    with open("output.pdf", "wb") as file:
        file.write(pdf_content)

In this passage of code:

• Utilizing the OpenTelemetry tracer, we begin a new span called pdf_generation.
• We use IronPDF to turn HTML material into a PDF document during this time.
• A file called output.pdf contains the generated PDF material.
