## About this task

Save time in resolving the current alert by reviewing how similar alerts were resolved. Provide resolution consistency by resolving similar alerts in the same way.

## Procedure

1.  Navigate to **All** > **Event Management** > **All Alerts**.

2.  In the list of alerts, click the alert record that you want to investigate.

3.  In the alert record, click the **Similar Alerts** tab.

    Alerts that are similar to the alert that is being investigated are listed.

    By default, up to 10 similar alerts are listed. You can modify this value by setting the `evt_mgmt.similarity_max_similar_alerts_shown` property.

4.  If you configured a threshold, in the Related links area, click **Show Similarities Details**.

    The Sys ID and confidence level of each similar alert is displayed. The Confidence level is an indication of how the similar alert matches the parameters that you set. As an example, a high confidence percentage value indicates a higher likelihood of similarity of the alerts to the values that you set.
