Default Integrations

System integrations are integrations enabled by default that integrate into the standard library or the interpreter itself. Sentry documents them so you can see what they do and that they can be disabled if they cause issues. To disable all system integrations, set default_integrations=False when calling init().

Atexit

Import name: sentry_sdk.integrations.atexit.AtexitIntegration

This integrates with the interpreter's atexit system to automatically flush events from the background queue on interpreter shutdown. Typically, one does not need to disable this. Even if the functionality is not wanted, it's easier to disable it by setting the shutdown_timeout to 0 in the options passed to init().

Excepthook

Import name: sentry_sdk.integrations.excepthook.ExcepthookIntegration

This integration registers with the interpreter's except hook system. Through this, any exception that is unhandled will be reported to Sentry automatically. Note that exceptions raised in interactive interpreter sessions will not be reported.

Options

You can pass the following keyword arguments to ExcepthookIntegration():

• always_run:

  Bash

  Copied

  $ python
  >>> import sentry_sdk
  >>> from sentry_sdk.integrations.excepthook import ExcepthookIntegration
  >>> sentry_sdk.init(..., integrations=[ExcepthookIntegration(always_run=True)])
  >>> raise Exception("I will become an error")
  

  By default, the SDK does not capture errors occurring in the REPL (always_run=False).

Deduplication

Import name: sentry_sdk.integrations.dedupe.DedupeIntegration

This integration deduplicates certain events. The Sentry Python SDK enables it by default, and it should not be disabled except in rare circumstances. Disabling this integration, for instance, will cause duplicate error logging in the Flask framework.

Stdlib

Import name: sentry_sdk.integrations.stdlib.StdlibIntegration

The stdlib integration instruments certain modules in the standard library to emit breadcrumbs. The Sentry Python SDK enables this by default, and it rarely makes sense to disable.

• Any outgoing HTTP request done with httplib will result in a breadcrumb being logged. urllib3 and requests use httplib under the hood, so HTTP requests from those packages should be covered as well.

• Subprocesses spawned with the subprocess module will result in a breadcrumb being logged.

Modules

Import name: sentry_sdk.integrations.modules.ModulesIntegration

Sends a list of installed Python packages along with each event.

Argv

Import name: sentry_sdk.integrations.argv.ArgvIntegration

Adds sys.argv as an extra attribute to each event.

Logging

Import name: sentry_sdk.integrations.logging.LoggingIntegration

See Logging

Threading

Import name: sentry_sdk.integrations.threading.ThreadingIntegration

Reports crashing threads.

This integration also accepts an option propagate_scope, which influences the way data is transferred between threads. If set to True (default), the current scope will be shared between threads and scope data (such as tags) will be transferred from the parent thread to the child thread.

Next are two code samples that demonstrate what boilerplate you would have to write without propagate_scope. This boilerplate is still sometimes necessary if you want to propagate context data into a thread pool, for example.

Manual propagation

import threading

import sentry_sdk

sentry_sdk.init(...)

sentry_sdk.set_tag("mydata", 42)

def run(thread_scope):
    thread_scope.capture_message("hi")  # event will have `mydata` tag attached

# We take all context data (the tags map and even the entire client
# configuration), and pass it as explicit variable
# into the thread.
with isolation_scope() as thread_scope:
    tr = threading.Thread(target=run, args=[thread_scope])
    tr.start()
    tr.join()

Automatic propagation

import threading

import sentry_sdk
from sentry_sdk.integrations.threading import ThreadingIntegration

sentry_sdk.init(
    ...,
    integrations=[
        ThreadingIntegration(propagate_scope=True),
    ],
)

sentry_sdk.set_tag("mydata", 42)

def run():
    sentry_sdk.capture_message("hi")  # event will have `mydata` tag attached

# The threading integration hooks into the stdlib to automatically pass
# existing context data when a `Thread` is instantiated.
tr = threading.Thread(target=run)
tr.start()
tr.join()
