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. There is nothing to do for you except initializing the Sentry SDK.

import sentry_sdk
from sentry_sdk.integrations.redis import RedisIntegration

sentry_sdk.init(
    dsn='https://examplePublicKey@o0.ingest.sentry.io/0',
    # Set traces_sample_rate to 1.0 to capture 100%
    # of transactions for performance monitoring.
    traces_sample_rate=1.0,
)

The Redis integration is enabled automatically if you have the redis package installed.

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
    rc = RedisCluster(host='localhost', port=16379)

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

Integration Options

If you want to change the default behavior of the Redis integration, you need to instantiate the integration manually to pass options to the integration and then pass it to Sentry's init function.

max_data_size

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

• When you set max_data_size to a value that evaluates to False (like 0 or None) no trimming will take place.
• You can set max_data_size to an integer to control how many characters should be collected.

Example for disabling data trimming, the whole Redis command will be recorded:

import sentry_sdk
from sentry_sdk.integrations.redis import RedisIntegration

sentry_sdk.init(
    dsn='https://examplePublicKey@o0.ingest.sentry.io/0',
    integrations=[
        RedisIntegration(max_data_size=None),
    ]
)

Example of keeping just a maximum of 50 characters of Redis commands:

import sentry_sdk
from sentry_sdk.integrations.redis import RedisIntegration

sentry_sdk.init(
    dsn='https://examplePublicKey@o0.ingest.sentry.io/0',
    integrations=[
        RedisIntegration(max_data_size=50),
    ]
)
