Heartbeats Sent Number of Heartbeats Received Total number of heartbeat packets received by the local ACE. Number of Heartbeats Missed Total number of heartbeat intervals that transpired with no heartbeats received. Number of Unidirectional HBs Received Number of heartbeats (HBs) received by the local peer that indicate the remote peer is not receiving HBs. The remote peer is sending heartbeats, but not receiving any. Note Both peer appliances send heartbeat packets and each packet indicates whether the other peer has been receiving heartbeats. Number of HB Timeout Mismatches Number of times that the local peer received a heartbeat (HB) from the remote peer with a mismatched heartbeat interval. If the heartbeat intervals do not match, a peer adjusts its interval to the lower of the two intervals. Note The heartbeat interval should be the same on both peer appliances. Each heartbeat packet contains the configured interval in the packet. When a peer receives a heartbeat packet, it checks to see if the interval in the heartbeat packet matches the interval configured locally. Num of Peer Up Number of times that the local ACE sent a Peer Up message Events Sent to the remote ACE. Num of Peer Down Events Sent Number of times that the local ACE sent a Peer Down message to the remote ACE. 7-52 Cisco 4700 Series Application Control Engine Appliance Administration Guide OL-11157-01
