Tool of the Week: Sentry

Sentry is not just error logging. Used well, it is the difference between a 3-hour and a 20-minute incident response.

The Setup Most Teams Get Wrong

Most teams install Sentry, ignore the noisy alerts, and turn off notifications. Here is the better approach:

Step 1: Set up release tracking

Link every deploy to a Sentry release so you know exactly which deploy introduced an error.

Step 2: Configure alert rules properly

• Critical: new error type never seen before — immediate Slack/PagerDuty
• Warning: error rate increase over 10% baseline — Slack only
• Info: weekly digest of top errors by volume

Step 3: Use Performance Monitoring

Sentry's distributed tracing shows exactly where slow endpoints spend their time across services.

Verdict

• Free tier: sufficient for solo projects and small teams
• Team tier ($26/month): worth it for any production system
• Essential config: release tracking plus smart alert rules. Without these, you are paying for noise.
