# opentelemetry-instrumentation-jinja2 — OpenTelemetry jinja2 instrumentation

License: permissive · Maintenance: active · Downloads: 5.0M/mo

## What it is and what it does

This package integrates Jinja2 template rendering into OpenTelemetry's distributed tracing system. It automatically instruments Jinja2 environments to emit spans and metrics whenever templates are compiled or rendered, allowing you to observe template performance and behavior as part of your broader application telemetry. The instrumentation captures template names, rendering duration, and other execution details.

It is designed for applications already using OpenTelemetry for observability—it acts as a bridge between Jinja2 and your existing tracing infrastructure. The package depends on opentelemetry-api, opentelemetry-instrumentation, and wrapt to hook into Jinja2's execution without modifying your template code.

Use it for:

- Monitor template rendering latency in web applications to identify performance bottlenecks in view generation.
- Correlate template execution with upstream and downstream service calls in distributed tracing dashboards.
- Debug template-related errors by examining spans and context propagation across your observability platform.
- Measure template compilation and rendering costs in high-throughput applications serving many concurrent requests.
- Audit which templates are executed and how often in production environments for compliance or optimization.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Adds OpenTelemetry tracing instrumentation to Jinja2 template rendering, capturing metrics and traces for template execution within your observability pipeline.

Yes, if you are already using OpenTelemetry in your application and render Jinja2 templates. It adds observability with minimal overhead and no code changes to your templates. Not necessary if you are not using OpenTelemetry or do not use Jinja2. Beta status (0.65b0) means it is stable enough for production but may see API changes.

## Install

pip install opentelemetry-instrumentation-jinja2
uv add opentelemetry-instrumentation-jinja2
poetry add opentelemetry-instrumentation-jinja2

## Installing opentelemetry-instrumentation-jinja2

Before you install: Low install friction with three lightweight runtime dependencies. Actively maintained as of 2026-08-14 with recent releases; part of the OpenTelemetry Python contrib ecosystem.

License in practice: Apache-2.0 permissive license allows use in commercial and open-source projects with minimal restrictions.

Quickstart:

pip install opentelemetry-instrumentation-jinja2

from opentelemetry.instrumentation.jinja2 import Jinja2Instrumentor
from jinja2 import Environment

Jinja2Instrumentor().instrument()
env = Environment()
template = env.from_string('Hello {{ name }}')
template.render(name='World')

Requires Python 3.10 or later; requires an active OpenTelemetry tracer/exporter configured in your application.

Verify before relying:

- Whether instrumentation works with Jinja2 versions prior to the package's first release in 2020
- Performance overhead of instrumentation on high-volume template rendering
- Compatibility with async Jinja2 environments
