1. Missing or Delayed Error Reports

Understanding the Issue

Errors are not appearing in the Rollbar dashboard or are delayed.

Root Causes

• Incorrect API key configuration.
• Rate limiting causing event throttling.
• Client-side errors blocked by Content Security Policy (CSP).

Fix

Verify the API key in the environment configuration:

export ROLLBAR_ACCESS_TOKEN="your-token-here"

Check rate limits in Rollbar settings:

curl -H "X-Rollbar-Access-Token: your-token" https://api.rollbar.com/api/1/rate_limit/

Allow Rollbar in CSP settings:

Content-Security-Policy: connect-src https://api.rollbar.com

2. Integration Failures

Understanding the Issue

Rollbar fails to integrate with frameworks such as Node.js, Python, or React.

Root Causes

• Incorrect SDK installation or missing dependencies.
• Improper initialization of Rollbar client.
• Conflicting logging configurations.

Fix

Ensure the Rollbar SDK is installed:

npm install --save rollbar

Initialize Rollbar correctly:

const Rollbar = require("rollbar");
const rollbar = new Rollbar({
    accessToken: "your-token-here",
    captureUncaught: true,
    captureUnhandledRejections: true
});

Verify logging settings:

console.log(rollbar.options);

3. Performance Bottlenecks

Understanding the Issue

Rollbar causes application slowdowns or excessive memory usage.

Root Causes

• High volume of error logs overwhelming the system.
• Synchronous logging slowing down request handling.
• Excessive payload size in error reports.

Fix

Enable asynchronous logging:

rollbar.configure({
    payload: {
        maxItems: 1000,
        itemsPerMinute: 100
    }
});

Reduce the amount of logged data:

rollbar.log("Error occurred", { errorType: "critical" });

Monitor application performance:

top -o %CPU

4. Incorrect Alert Configurations

Understanding the Issue

Rollbar alerts are too frequent, missing, or not triggering correctly.

Root Causes

• Incorrect notification settings.
• Filters preventing error alerts.
• Rate limits affecting alert delivery.

Fix

Verify alert settings in Rollbar:

Settings → Notifications → Configure Alerts

Check filters applied to alerts:

Ensure severity level is set correctly (Critical, Warning, Info).

Confirm webhook delivery status:

curl -X GET https://api.rollbar.com/api/1/webhooks/

5. Data Retention Limitations

Understanding the Issue

Older logs are missing or Rollbar storage is exceeding quotas.

Root Causes

• Data retention policies automatically deleting logs.
• Exceeded event storage limits.
• Incorrect project settings for log storage.

Fix

Adjust data retention policies:

Settings → Account → Data Retention

Upgrade Rollbar plan for more storage:

Check pricing plans for higher log limits.

Export logs before deletion:

curl -X GET https://api.rollbar.com/api/1/items/

Conclusion

Rollbar is an essential DevOps tool, but troubleshooting missing error reports, integration failures, performance issues, incorrect alert configurations, and data retention limitations is necessary for maintaining smooth error tracking. By ensuring proper API configurations, optimizing logging, and monitoring system resources, developers can fully leverage Rollbar’s capabilities.
