Managing Stacks › Display Stack Performance

Display Stack Performance

The IP Resource Monitor lets you display the following types of performance data for a TCP/IP stack:

• Performance history (from the most recent samples to samples up to the last ten weeks)
  • Connection, Telnet, and FTP workload
  • Stack network interface
  • IP, TCP, and UDP activity
  • Stack address space and ports
• IP, TCP, and UDP activity (current snapshot)
• Byte and packet throughput (from the last five minutes to the last hour)

Display Performance History

Attribute List panels let you monitor the performance and health status of a stack.

To display stack performance

1. Enter one of the following commands beside a stack entry on the IP Resource Monitor:
   • WC for stack connection workload performance
   • WT for stack Telnet workload performance
   • WF for stack FTP workload performance
   • WI for stack network interface performance
   • IP for stack IP, TCP, and UDP performance
   • H for stack address space and port performance

     The list of monitored attributes appears. You can use the F6 function key to control whether the values are refreshed each time a new sample is gathered.

     Note: To expand or collapse the display of a listed qualifier, move the cursor to the qualifier and press Enter. To expand or collapse all qualifiers, press F4.

2. Enter one of the following actions beside an attribute for more details:
   • D lists the samples
   • S displays the Hourly Summary Graph
   • H displays the Hourly Summary List
   • DL displays the Daily Summary List
   • W displays the Weekly Interval List

     Press F5 (Overview) to compare this resource with others on the system.

Note: For more information, press F1 (Help).

Note: You can monitor other attributes. To monitor them, they must be added to the monitored list. For more information, see the Implementation Guide. If authorized, you can update the monitored list through the UM line command.

Display IP, TCP, and UDP Activity Summary

You can display a summary of IP, TCP, and UDP activities on a stack.

To display the summary

1. Enter IPM next to a stack entry on the IP Resource Monitor.

   The summary appears containing statistics on IP, TCP, and UDP activities. This summary is a snapshot taken at the time of the request.

Display Byte and Packet Throughput

You can display the most recent byte and packet counts for a stack.

To display byte and packet throughput

1. Enter TRS (Display IP Traffic Statistics) beside a STACK class resource on the IP Resource Monitor.

   The Traffic Statistics Selection List appears.

2. Enter S beside the type of statistics you want to view.

   The panel shows the number of bytes and packets sent and received by the ports in one-minute intervals over the last five minutes, and the percentage this represents of the total traffic for the stack.

   Note: To display the statistics in five-minute intervals over the last hour, press F12 (LastHour).
