Users should NEVER directly connect to a collector. You should be looking at why the performance is degraded and deal with that issue.
AppMap should be turned off and left off. Use Team Center instead.
Collectors are NEVER to have Management Modules. You will cause duplicate metrics and alerts to be created. Collectors are responsible for harvesting data; MOM is the presentation layer.
As I stated before, fix your performance problems. If you can't resolve the issue on your own by looking at the logs, consider posting a new question on the community or open a support ticket.
