View SPAN Receiver Statistics

View Packets counter statistics for information about unoptimized TCP packet data that the CA Standard Monitor receives on a particular Monitor NIC.

Important: Before you begin, synchronize the monitoring device. The monitoring device must be synchronized to display its counter windows.

The Packets counter displays the following information:

Received Packets

Identifies the total number of packets that are received, but not inspected, by the Monitor NIC on the CA Standard Monitor.

Note: Inspection of the packet header allows you to use these packets to calculate application response time metrics. For more information, see Total Seen Packets.

Dropped Packets

Identifies the total number of packets that arrived at the Monitor NIC but the packet header was never inspected. If the CA Standard Monitor is too busy processing other packets and the packet capture driver buffer is full, the packet is dropped.

To Server Packets

Identifies the total number of packets that are sent from a client to a server.

From Server Packets

Identifies the total number of packets that are sent from a server to a client.

To Server Bytes

Identifies the total number of bytes sent from a client to a server.

From Server Bytes

Identifies the total number of bytes sent from a server to a client.

Total Seen Packets

Identifies the total number of packets that match a specified application port, client network, and server subnet.

Note: If the monitor is performing normally, the number of Total Seen Packets matches the number of Received Packets. If the monitor cannot inspect all the packets that it receives, the number of Total Seen Packets is less than the number of Received Packets, and the number of Dropped Packets increases. For more information, see Dropped Packets.

Total Captured Bytes

Identifies the total byte count for packets that match a specified application port, client network, and server subnet.

Note: The CA Standard Monitor inspects each packet header to determine whether the packet matches a specified application port, client network, and server subnet. For more information, see Total Seen Packets.

Accepted Sessions

Identifies the number of TCP sessions that match a valid application, server, and network combination on the management console.

Rejected for Server

Identifies the number TCP sessions where the server IP did not match a server subnet.

Rejected for Client

Identifies the number TCP sessions where the client IP did not match a client network.

Rejected for Port

Identifies the number TCP sessions where the server port matched the list of ports that the management console ignores.

Rejected for Positive

Reserved for future use.
