AppManager => SNMP => F5 BIG-IP = "Service is not Running."

AppManager => SNMP => F5 BIG-IP = "Service is not Running."

When I try to set up a monitor for a big-ip device using snmp, I get an error: Service is not Running.
Service is runnig. It works with Nagios.
IP, mask, port, community string are correct.
snmp.config and hosts.allow are set correct.

I've found this: http://www.manageengine.com/products/applications_manager/troubleshoot.html#m24

It says:
Reason: The Service is running over UDP (User Datagram Protocol). Service Monitoring can discover services running in only connection protocol such as TCP (Transmission Control Protocol).
Solution:
 Discover SNMP Agent through Services->SNMP Agent. Refer Discovering SNMP Agent section of New Monitor.
Right, the service is running over UDP. BUT I don't understand the solution. What can I really do to get it fixed?
