A small set of utilities for configuring sentry & modifying normal sentry_sdk functionality
Project description
Lenders Sentry Utils
This is a package containing Sentry related utilities used across several Lenders Cooperative projects.
Installation
$ pip install lenders-sentry-utils
Usage
There are two major components in the package, sentry_init
and TrafficSplittingHttpTransport
.
These are explained in the sections below.
Additionally, there is one minor component, capture_exception
.
This is a simple wrapper for sentry_sdk.capture_exception
that adds an event processor to protect a request's body if it exists in the event.
Sentry Init
This package's sentry_init
is a wrapper for sentry_sdk.init
with default values and automatic checking of environment variables.
The following table lists each parameter and its relevant information.
Any parameter with no description directly corresponds to a sentry_sdk.init
option.
Parameter name | Type | Default value | Description |
---|---|---|---|
env | Env | None | An Env object to search if dsn , environment , or release are not passed |
dsn | str | env("SENTRY_DSN") | |
environment | str | env("BASE_URL") | |
release | str | env("VERSION") | |
debug | bool | False | |
send_default_pii | bool | True | |
traces_sample_rate | float | 0.1 | |
integrations | List | Django, Celery, Redis integrations | |
transport | Transport | HTTPTransport | |
before_send | function | None |
Note: env
, dsn
, and environment
are dependent on each other to a certain degree.
If dsn
or environment
are not passed as parameters, env
must be passed in order to pull the corresponding environment variable.
Additionally, if dsn
or environment
are passed, the passed value will be used even if the corresponding environment variable exists in env
.
release
is similar to dsn
and environment
, but it is fully optional.
Sentry Init Examples
from lenders_sentry_utils import sentry_init
from environ import Env
env = Env(
SENTRY_DSN = (str, 'https://PK@sentry.io/0'),
BASE_URL = (str, 'base.com'),
)
# Minimum viable function call
sentry_init(env=env)
# Forcing a DSN that's not in the environment
different_dsn = 'https://different@not.sentry.io/3'
sentry_init(env=env, dsn=different_dsn)
# Setting DSN and environment without using environment variables
sentry_init(dsn=different_dsn, environment='special.env.com')
TrafficSplittingHttpTransport
TrafficSplittingHttpTransport
is a custom transport that splits transaction events to a second DSN while still sending error events to the primary DSN.
This is usually done for billing purposes to ensure that all errors can be reported to Sentry.
To use this transport, the environment variable SENTRY_TRANSACTIONS_DSN
must be set with the second DSN as its value.
If this environment variable is not set, transaction events will instead be discarded.
TrafficSplittingHttpTransport Examples
import lenders_sentry_utils as lsu
from environ import Env
drop_transactions_env = Env(
SENTRY_DSN = (str, 'https://error_dsn@sentry.io/0'),
BASE_URL = (str, 'base.com'),
)
send_transactions_env = Env(
SENTRY_DSN = (str, 'https://error_dsn@sentry.io/0'),
BASE_URL = (str, 'base.com'),
SENTRY_TRANSACTIONS_DSN = (str, 'https://transactions_dsn@sentry.io/0'),
)
# Example 1: Sending transaction events
lsu.sentry_init(env=send_transactions_env, transport=lsu.TrafficSplittingHttpTransport)
# Example 2: Ignoring transaction events
lsu.sentry_init(env=drop_transactions_env, transport=lsu.TrafficSplittingHttpTransport)
