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.
Review a list of issues
Go to the Performance Monitoring section of the Firebase console, then click the Issues tab.
Review the list of potential performance issues. The most recent issues are listed first.
Mute or close issues
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.
Muting hides the issue regardless of current or future status. Closing marks the issue as fixed, and Performance Monitoring can reopen the issue if it regresses.
Go to the Performance Monitoring section of the Firebase console, then click the Issues tab.
On the issue you want to hide, click , then select Mute or Close.
You can come back to closed or muted issues and select 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).
Go to the Performance Monitoring section of the Firebase console, then click the Issues tab.
On the issue type you want to modify, click , then select Edit threshold.
If you no longer want to see issue notifications for that issue type, select Delete threshold.
Select Move threshold, then adjust the threshold accordingly, or select Reset to default to restore the default threshold.
