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
Go to the Performance Monitoring dashboard in the Firebase console.
Review the list of potential performance issues. Top issues are listed in the section labeled Issues this month by importance.
To see all issues, click See all.
Mute or close issues
Open the Issues tab in the Firebase console.
On the issue you want to hide, click the menu, then click Mute or Close. You can come back to closed or muted issues and click Reopen from the menu to open them again.
Configure issue thresholds
To change the frequency or sensitivity that Performance Monitoring uses to flag issues, you can modify the default thresholds by issue type (where possible).
Open the Performance Monitoring dashboard in the Firebase console.
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.
Select Move threshold, then adjust the threshold accordingly, or select Reset to default to restore the default threshold.
