The Border Gateway Protocol (BGP) Peer Status active monitor checks the status of the connections between a router using BGP protocol and its Internet Service Provider (ISP) device peers. When the monitored router detects any device peer is not fully connected, WhatsUp Gold reports the monitor is Down.
When viewed on the State Change Timeline, you'll see detailed information from the router in the Message column including the IP address of the affected device peer, the current status of the connection, and the number of transitions recorded at the time the connection was interrupted or broken.
Note: Possible connection statuses can be found using the SNMP MIB Walker.
The number of transitions refers to how many times the connection intermittently switched between fully connected and either partially or fully disconnected before remaining in a disconnected state. For example, if the device peer was fully connected, then fully disconnected with no intermittent data flow, the number of transitions would be 0. If the connection went down, then up briefly, then down again before remaining disconnected, the number of transitions would be 1.
To configure, simply provide a unique name and description for the monitor. SNMP timeout and retries may be modified as well if desired.
