Using Alerts › Graphic Alert Displays

Graphic Alert Displays

The display of the bars (the variable values) of each graph depends on the type of monitor you have:

• Color Monitor

  Bars that exceed the alert scale are red and those that do not are green.

• Monochrome Monitor with Reverse Video Capability

  Bars that exceed the alert scale appear as a row of high intensity reverse video hyphens (-) and those that do not appear as a row of normal intensity hyphens.

• Monochrome Monitor Without Reverse Video Capability

  Bars that exceed the alert scale appear as a row of greater than signs (>) and those that do not appear as a row of hyphens (-).

Graphic Alerts Function Keys

You can use the following function keys in the graphic alerts facility:

• F1

  Accesses online help.

• F2

  Deactivates refresh mode for current interval statistics so that the screen is refreshed at every base interval. To reactivate refresh mode, press F2 again. The BASEITVL statement in the INITPRM file sets the base interval.

• PA1

  Recalls the last explicit command entered.

• PA2

  Recalls the data previously cleared on a menu.

• F4/F16

  Deletes the graph.

• F7/F19

  Pages backward.

• F8/F20

  Pages forward.

• CLEAR

  Clears data input fields on a menu.

Note: Each graph or set of graphs has its own command line. To use a function key function such as F8 (scroll down) on a particular graph, ensure that the cursor is on the correct command line.

Display Notes

When N/A (not available) appears on a graph, the information needed to calculate the value is not collected. This can occur under the following conditions:

• When you select both VTAM and NCP data to display for a resource and the region is not monitoring the NCP.
• When you request both VTAM and NCP data and the resource shown is defined in a local major node.
• When you request line or PU utilization percent and line speed is not coded in the NCP.

When you select applications, only data for applications with active sessions is displayed.

When you select logical units (LU), only those currently in session are shown. Each session appears as a separate resource in the graph. Mapped virtual terminal sessions are excluded from the graph unless a FORAPPL resource list is used. (Mapped virtual terminal sessions have a V in the VL column on the Terminal Traffic and Response Time display.)

GMAXENT Parameter

The maximum number of resources listed on each graph is determined by the GMAXENT statement in the INITPRM member of file.

For best results, set the GMAXENT statement as follows:

• If you want to monitor LUs, set GMAXENT to the value of MAXLU
• If you do not want to monitor LUs, set GMAXENT to the number of PUs, lines, or APPLs, whichever is higher

Note: If, for example, you set the GMAXENT statement to 100, the alert displays will list data from 100 random resources, rather than the 100 worst or best resources.
