OpenTelemetry Pyramid Instrumentation

Pyramid instrumentation supporting pyramid, it can be enabled by using PyramidInstrumentor.

Usage

There are two methods to instrument Pyramid:

Method 1 (Instrument all Configurators):

from pyramid.config import Configurator
from opentelemetry.instrumentation.pyramid import PyramidInstrumentor

PyramidInstrumentor().instrument()

config = Configurator()

# use your config as normal
config.add_route('index', '/')

Method 2 (Instrument one Configurator):

from pyramid.config import Configurator
from opentelemetry.instrumentation.pyramid import PyramidInstrumentor

config = Configurator()
PyramidInstrumentor().instrument_config(config)

# use your config as normal
config.add_route('index', '/')

Using pyramid.tweens setting:

If you use Method 2 and then set tweens for your application with the pyramid.tweens setting, you need to explicitly add opentelemetry.instrumentation.pyramid.trace_tween_factory to the list, as well as instrumenting the config as shown above.

For example:

from pyramid.config import Configurator
from opentelemetry.instrumentation.pyramid import PyramidInstrumentor

settings = {
    'pyramid.tweens', 'opentelemetry.instrumentation.pyramid.trace_tween_factory\nyour_tween_no_1\nyour_tween_no_2',
}
config = Configurator(settings=settings)
PyramidInstrumentor().instrument_config(config)

# use your config as normal.
config.add_route('index', '/')

Configuration

Exclude lists

To exclude certain URLs from tracking, set the environment variable OTEL_PYTHON_PYRAMID_EXCLUDED_URLS (or OTEL_PYTHON_EXCLUDED_URLS to cover all instrumentations) to a string of comma delimited regexes that match the URLs.

For example,

export OTEL_PYTHON_PYRAMID_EXCLUDED_URLS="client/.*/info,healthcheck"

will exclude requests such as https://site/client/123/info and https://site/xyz/healthcheck.

Capture HTTP request and response headers

You can configure the agent to capture specified HTTP headers as span attributes, according to the semantic convention.

Request headers

To capture HTTP request headers as span attributes, set the environment variable OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_REQUEST to a comma delimited list of HTTP header names.

For example,

export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_REQUEST="content-type,custom_request_header"

will extract content-type and custom_request_header from the request headers and add them as span attributes.

Request header names in Pyramid are case-insensitive and - characters are replaced by _. So, giving the header name as CUStom_Header in the environment variable will capture the header named custom-header.

Regular expressions may also be used to match multiple headers that correspond to the given pattern. For example:

export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_REQUEST="Accept.*,X-.*"

Would match all request headers that start with Accept and X-.

To capture all request headers, set OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_REQUEST to ".*".

export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_REQUEST=".*"

The name of the added span attribute will follow the format http.request.header.<header_name> where <header_name> is the normalized HTTP header name (lowercase, with - replaced by _). The value of the attribute will be a single item list containing all the header values.

For example: http.request.header.custom_request_header = ["<value1>,<value2>"]

Response headers

To capture HTTP response headers as span attributes, set the environment variable OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_RESPONSE to a comma delimited list of HTTP header names.

For example,

export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_RESPONSE="content-type,custom_response_header"

will extract content-type and custom_response_header from the response headers and add them as span attributes.

Response header names in Pyramid are case-insensitive. So, giving the header name as CUStom-Header in the environment variable will capture the header named custom-header.

Regular expressions may also be used to match multiple headers that correspond to the given pattern. For example:

export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_RESPONSE="Content.*,X-.*"

Would match all response headers that start with Content and X-.

To capture all response headers, set OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_RESPONSE to ".*".

export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_RESPONSE=".*"

The name of the added span attribute will follow the format http.response.header.<header_name> where <header_name> is the normalized HTTP header name (lowercase, with - replaced by _). The value of the attribute will be a single item list containing all the header values.

For example: http.response.header.custom_response_header = ["<value1>,<value2>"]

Sanitizing headers

In order to prevent storing sensitive data such as personally identifiable information (PII), session keys, passwords, etc, set the environment variable OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SANITIZE_FIELDS to a comma delimited list of HTTP header names to be sanitized. Regexes may be used, and all header names will be matched in a case-insensitive manner.

For example,

export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SANITIZE_FIELDS=".*session.*,set-cookie"

will replace the value of headers such as session-id and set-cookie with [REDACTED] in the span.

Note

The environment variable names used to capture HTTP headers are still experimental, and thus are subject to change.

API

class opentelemetry.instrumentation.pyramid.PyramidInstrumentor(*args, **kwargs)[source]

Bases: opentelemetry.instrumentation.instrumentor.BaseInstrumentor

instrumentation_dependencies()[source]

Return a list of python packages with versions that the will be instrumented.

The format should be the same as used in requirements.txt or pyproject.toml.

For example, if an instrumentation instruments requests 1.x, this method should look like:

def instrumentation_dependencies(self) -> Collection[str]:

return [‘requests ~= 1.0’]

This will ensure that the instrumentation will only be used when the specified library is present in the environment.

Return type

Collection[str]

static instrument_config(config)[source]

Enable instrumentation in a Pyramid configurator.

Parameters

config – The Configurator to instrument.

static uninstrument_config(config)[source]
