PA Metrics

PA provides the basic metrics for both TCP and UDP protocols and for both IPv4 and IPv6. Some of the metrics are dynamically exported in the form of the delta value for the interval. These include the client/server bytes and packets metrics. In addition, PA server/client bytes/packets metrics are for layer-3 measurements and in a TCP flow are counted up to the second FIN. The rest of the metrics are relatively static and remain the same across different export intervals.

PA keeps exporting the measurements as long as the flow stays active. As a consequence, the collector might occasionally observe zero values for dynamic metrics such as the client/server bytes/packets. For all the UDP flows, the TCP related metrics such as ART metrics would be zero. Another note for the Input/Output interface metrics is that these are corresponding to the interface from which the flow enters/leaves the box.

All the PA metrics can be exported either through Netflow v9 or IPFIX protocol. PA metrics are summarized below.


Field Name Export ID CLI Description
Client Bytes 1 collect counter client bytes Total bytes sent by initiator of the connection. Counted up to the second FIN if for a TCP flow.
Client Packets 2 collect counter client packets Total packets sent by initiator of the connection. Counted up to the second FIN if for a TCP flow.
Interface Input 10 collect interface input Interface name from which flow is entering the box.
Interface Output 14 collect interface output Interface name from which flow is exiting out the box.
Server Bytes 23 collect counter server bytes Total bytes sent by responder of the connection. Counted up to the second FIN if for a TCP flow.
Server Packets 24 collect counter server packets Total packets sent by responder of the connection. Counted up to the second FIN if for a TCP flow.
Datalink Mac Source Address Input 56 collect datalink mac source address input MAC address of source device from Input side
IPv4 DSCP 195 collect ipv4 dscp IPv4 DSCP value
IPv6 DSCP 195 collect ipv6 dscp IPv6 DSCP value
