Distributed Monitors tab not showing SPA and SPB

Hi, In Unisphere, System>Monitoring And Alerts > Notification > Distributed Monitors tab is not showing SPA and SPB Images. As these are missing, we are getting failure notice when we are trying to handle SNMP templates through Navispere. Any idea why these are missing and how to configure those back?

Cannot communicate to the distributed event monitor.
