In v7.1.x, we have removed some of that functionality in the UI, and replaced it with "dslc" from the CLI except for the System Events as shown below.

To enable email notifications for the network capture event enter the following command at the terminal prompt:

dslc enable category capture email

Sample output:

[root@SA ~]# dslc enable category capture email
Enable method: email for category capture
