sues, for
example, in the following scenarios:

  * You select relevant metrics on the dashboard and you notice a big delta. 
  * In the traces table you sort to display the largest deltas at the top, and you see a significant percentage change. 
  * You receive an email alert notifying you of a performance issue. 

You can access the troubleshooting page in the following ways:

  * On the metric dashboard, click the **View metric details** button. 
  * On any metric card, select  ** more_vert  => View details ** . The troubleshooting page displays information about the metric you selected. 
  * In the traces table, click a trace name or any metric value in the row associated with that trace. 
  * In an email alert, click **Investigate now** . 

When you click a trace name in the traces table, you can then drill down into
metrics of interest. Click the  **Filter add  ** button to filter the data by
attribute, for example:

attribute_native-1.png)

  * Filter by _App version_ to view data about a past release or your latest release 
  * Filter by _Device_ to learn how older devices handle your app 
  * Filter by _Country_ to make sure your database location isn't affecting a specific region
