Hi Jon,
Amon Packet Arrival Graph shows the amount of Amon packets which have arrived on AMP and the processing rate by the PAPI daemon
PAPI CPU utilization worker graphs shows the overall CPU utilization by the various daemons which process the packets received
Amon Message loss Graph shows if any packets are missed or dropped(Network loss). if network is not healthy enough. However, Amp have the capability to check the missed data and request the controller again for that packaet.
Regards,
Vishnu
