Getting Started with Sentry: Chinese Developer Guide and Extension Handbook

Overview

Sentry is an open‑source platform that provides error monitoring, performance monitoring, and metric analysis for more than 30 programming languages. It integrates with tools such as GitHub, Slack and Jira.

Event Pipeline Architecture

The simplified flow of an event through Sentry consists of the following steps: Relay retrieves project configuration from sentry-web. Relay caches the configuration in memory using Redis. Relay calculates event data and tracks quota, also stored in Redis. Symbolicator provides the helper service symbolicate-event for symbolication.

Alert triggering is performed by postprocess-event, which launches a Celery task. The task reads from the Kafka consumer on the eventstream queue.
