Displaying IBM Session Manager system activity statistics

See:

To display IBM Session Manager terminal statistics

From System view for a node, complete these steps:

  1. Select the Performance tab.
  2. If required, use the vertical scroll bar to reposition the 'frame' so that the Terminals section is visible.
  3. If the Terminals section is collapsed then to expand it, click on its heading.

Statistics on the number of input and output buffers from terminals and the number of bytes sent will be displayed. The number of terminals currently active and the maximum number that were active will also be shown, along with the time that the maximum number was observed.

To display IBM Session Manager session statistics

From System view for a node, complete these steps:

  1. Select the Performance tab.
  2. If required, use the vertical scroll bar to reposition the 'frame' so that the Sessions section is visible.
  3. If the Sessions section is collapsed then to expand it, click on its heading.

Statistics on the number of input and output buffers from sessions and the number of bytes sent will be displayed. The number of sessions currently active and the maximum number that were active will also be shown, along with the time that the maximum number was observed.

To display IBM Session Manager VTAM statistics

From System view for a node, complete these steps:

  1. Select the Performance tab.
  2. If required, use the vertical scroll bar to reposition the 'frame' so that the VTAM section is visible.
  3. If the VTAM section is collapsed then to expand it, click on its heading.

The number of ACBs currently open and the maximum number that were open are displayed, along with the time that the maximum number was observed. Similar information is also displayed for receive RPLs.

To display IBM Session Manager MISER statistics

Note: The IBM Session Manager Network Data Minimizer, MISER, provides the facility to reduce the amount of data traffic both to and from applications.

From System view for a node, complete these steps:

  1. Select the Performance tab.
  2. If required, use the vertical scroll bar to reposition the 'frame' so that the MISER section is visible.
  3. If the MISER section is collapsed then to expand it, click on its heading.

Statistics for the MISER feature will be displayed - see 'MISER statistics' below.

MISER statistics

Statistics for the MISER feature are summarized below. For details, see 'Network Data Minimizer (MISER)' in the IBM Session Manager Installation and Customization manual, which also explains the difference between MISER and Runlength compression.
Note: If applications are issuing WSFRPQs, and IBM Session Manager is simulating them, then the number of session output bytes is greater than the compression input bytes. The difference between the two values is the number of bytes saved by simulating WSFRPQs.
InBound
[spacer]

Buffers

Number of buffers from the terminal to the application which were processed by MISER.

BytesIn

Number of data bytes in buffers before MISER compression.

BytesOut

Number of data bytes in the buffers after MISER MDT compression (that is, after MDT fields not sent to the terminal have been added).

Compression

Percentage saved, calculated as:
100 - (BytesOut / (BytesIn / 100)).

OutBound
[spacer]

Buffers

Number of buffers from the application to the terminal which were processed by MISER.

BytesIn

Number of data bytes in buffers before MISER compression.

BytesOut

Number of data bytes in buffers after MISER outbound compression (that is, number of bytes sent to the screen).

Compression

Percentage saved, calculated as:
100 - (BytesOut / (BytesIn / 100)).

Compressed
[spacer]

Buffers

Number of buffers from the application to the terminal which were processed by the Runlength compression routine.

BytesIn

Number of data bytes in buffers before Runlength compression.

BytesOut

Number of data bytes in buffers after Runlength compression.

Compression

Percentage saved, calculated as:
100 - (BytesOut / (BytesIn / 100)).
