Hi,
On the SEPM home page, click on view details & select SONAR failures.
Also, you can construct custom filters by using the Basic Settings and Advanced Settings to change the information that you want to see. You can save your filter settings to the database so that you can generate the same view again in the future. When you save your settings, they are saved in the database. The name you give to the filter appears in the Use a saved filter list box for that type of logs and reports.
