Redis

The Redis integration hooks into the Redis client for Python and logs all Redis commands as breadcrumbs.

Install

pip install --upgrade 'sentry-sdk'

Configure

If you have the redis Python package in your dependencies, the Redis integration will be enabled automatically.

import sentry_sdk

sentry_sdk.init(
    dsn="https://examplePublicKey@o0.ingest.sentry.io/0",
    # Set traces_sample_rate to 1.0 to capture 100%
    # of transactions for tracing.
    traces_sample_rate=1.0,
    # Set profiles_sample_rate to 1.0 to profile 100%
    # of sampled transactions.
    # We recommend adjusting this value in production.
    profiles_sample_rate=1.0,
)

Verify

Standard Redis

import redis

def main():
    sentry_sdk.init(...)  # same as above
    r = redis.Redis(host='localhost', port=6379, decode_responses=True)

    with sentry_sdk.start_transaction(name="testing_sentry"):
        r.set("foo", "bar")
        r.get("foo")

main()

Redis Cluster

from redis.cluster import RedisCluster

def main():
    sentry_sdk.init(...)  # same as above
    rc = RedisCluster(host='localhost', port=16379)

    with sentry_sdk.start_transaction(name="testing_sentry"):
        rc.set("foo", "bar")
        rc.get("foo")

main()

Async Redis client

import asyncio
import redis.asyncio as redis

async def main():
    sentry_sdk.init(...)  # same as above
    r = redis.Redis(host='localhost', port=6379)

    with sentry_sdk.start_transaction(name="testing_sentry"):
        await r.set("foo", "bar")
        await r.get("foo")

asyncio.run(main())

These examples will create a transaction called testing_sentry in the Performance section of sentry.io, and create spans for the redis commands.

It takes a couple of moments for the data to appear in sentry.io.

Behavior

With Redis integration the following information will be available to you on Sentry.io:

• Performance information about requests to redis will be available in the waterfall diagram in the Performance section on Sentry.io.
• Redis commands will be added as breadcrumbs.
• If send_default_pii is set to True you will also see the data used in your redis commands.
• Data of the AUTH command will never be collected.

Options

By adding RedisIntegration explicitly to your sentry_sdk.init() call you can set options for RedisIntegration to change its behavior:

import sentry_sdk
from sentry_sdk.integrations.redis import RedisIntegration

sentry_sdk.init(
    # ...
    integrations=[
        RedisIntegration(
            max_data_size=None,
            cache_prefixes=["mycache", "template.cache"],
        ),
    ],
)

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

• max_data_size

By default RedisIntegration() will trim data collected after 1024 characters. You can change this behavior with the max_data_size parameter:

You can set max_data_size to an integer to control how many characters should be collected.

When you set max_data_size to a value that evaluates to False (like 0 or None), no trimming will take place. The whole Redis command will be recorded.

• cache_prefixes

You can specify a list of prefixes to Redis keys to define a key space that should be considered as cache. Cache keys will show up in the cache-monitoring dashboard, giving you more insight into your caching strategy.

For example, if you, set cache_prefixes to ["template.cache", "middleware.cache"], then access to all Redis keys starting with template.cache or middleware.cache will show up in your cache-monitoring dashboard.
