Hi Carrie,
Are you able to provide a screenshot of the button not being available or is it greyed out? When you click on the Add button, the relevant details should appear for creating a new view and the +Add Filter option should be available within this screen. It should then allow you to add in server, alert policy, job filter, etc.
I am sure that this is available as default when the installation happens and the monitor view access is controlled through the EEM policy MonitorViewControl -> MonitorViewControlDefault.
Thanks
Richie
