how to stop this error alerts
The shown host is configured for agent and SNMP. It looks like as it is only an SNMP device. Please remove the agent setting from the host configuration and the error should be gone.
thanks …

please suggest how to remove this warning
Have you configured SNMP correctly on the target system?
And then of course you have to tick SNMP under “Monitoring Agents” and enter the correct access data.
The message states that all services are no longer available, i.e. either no longer exist or simply cannot be accessed.
If you want the messages removed, all you have to do is perform a service discovery and remove the vanished services.
The message in the screenshot is “120 unmonitored services found” 
not fanished.
@Dharma the message is perfectly normal as it only states that new services are found now you have to decide if you want to monitor these services.
I should have read more carefully, but you’re right of course
