  • Debug - log debugging messages in addition to messages logged at the info level.
Log File

Number of Message Buffers

Number of message buffers. One message buffer is required for each message that is being simultaneously built. This setting can have a value from 1 - 65535, although the machine must have enough memory to hold the number of buffers specified.

Number of Packet Buffers

Number of network packet buffers to create per data channel. The size of one buffer is approximately the size of the Maximum Transmission Unit of the network interfaces being used. A larger number of packet buffers means that a larger burst of traffic can be handled without requiring resends. This setting can have a value from 1 - 4294967296.

Message Flush Interval (seconds)

Interval, in seconds, during which a partially filled message buffer must be idle before being sent on the network. This setting can have a value from 1 to 65535.

Latency Check Interval (seconds)

Determines in seconds how often the network latency between publisher and subscriber is checked. This setting can have a value from 1 - 65535.

Local Interface Local interface that the publisher uses to monitor administrative requests.
Admin Port

Port number used by the UAF agent to communicate with the subscriber. The subscriber listens for incoming administration requests on this port.

Max Connections

Determines the number of concurrent connections to the AdminChannel. Defaults to 10. Value must be in the range of 1 - 65535.

Resend Port Port number used by subscribers to request resends of dropped network packets, and to time network latency between publisher and subscriber.
Time to Live (hops) The limit on the number of routing devices a message may pass through before expiring.
