This appears to be a WebServer(?) agent that is not being recognized by the AppMon Server. WebServers (Apache, etc) use a local Master agent to aggregate data. Perhaps restarting the master agent process (Service) and the Apache (?) process might help. If that does not resolve it, I would open a support case. Be sure to include the whole log file from the master agent and apache (?) process in your support case.
