Track performance issues

Performance Monitoring automatically flags possible performance issues in your app when a significant number of traces or network requests exceed a predetermined threshold over a monthly period. These issues appear in your Performance Monitoring dashboard in the Firebase console, where you can review and manage them.

You can close, mute, and re-open issues. You can also change the thresholds that Performance Monitoring uses to flag issues for each issue type.

Review a list of issues

  1. Go to the Performance Monitoring dashboard in the Firebase console.

  2. Review the list of potential performance issues. Top issues are listed in the section labeled Issues this month by importance.

  3. To see all issues, click See all.

  2. On the issue type you want to modify, click Edit threshold from the menu.

    If you no longer want to see issue notifications for that issue type, click Delete threshold.
