The following information describes the areas of the TR TCP statistics report:

Local Host: If the policy was configured to limit by all sockets (also known as limit by port), this is either 255.255.255.255 or ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff. If the policy was configured to limit by each socket (also known as limit by port instance), this is the IP address bound to by the local listener applications. The value 0.0.0.0 indicates that the application bound to INADDR_ANY. The value :: indicates that the application bound to in6addr_any.
Date and Time: The stack date and time the statistics were reported.
Local Port: The port bound to by a local listener application.
Action: Indicates whether or not an action of LIMIT was specified in the policy that is in effect at the end of the statistics interval.
Peak: The highest number of concurrent connections from all sources during the statistics interval.
Peak Host: The IP address of the source host with the largest number of concurrent connections that also requested an additional connection during the statistics interval.
HostPeak: The number of allowed connections held by the source host identified in Peak Host.
Requests: The total number of new connection requests received during the statistics interval.
Warnings: The total number of connections that would have been denied during the statistics interval if a policy action of LIMIT had been in effect at the time of the request.
QosExcepts: The total number of connections that were allowed during this statistics interval because the QoS policy for a particular source IP guaranteed a higher number of connections to this port than were allowed by the TCP TR percentage of total connections for a single host.
Terminates: The total number of connections that were denied during the statistics interval because a policy action of LIMIT was in effect at the time of the request.
Current: The number of connections existing at the end of the statistics interval.
Duration: The number of seconds this port was in constrained state during this statistics interval.
SugLimit: A suggested value for the total number of connections limit that will avoid any connections being denied for exceeding either limit in future periods with the same number of total requests and requests from a single source. If a policy action of LIMIT was in effect then this value is 0.
SugPercent: A suggested companion value for the percentage of total connections that can be used by a single IP address. If a policy action of LIMIT was in effect then this value is 0.
