Creating Monitor Pictures

A.1 Interactive Definition of a Monitor Picture

Figure A–1 Interactively Defined Monitor Picture

THE TEST PICTURE AT 11:49:24

SOME DATA ITEM: 0

OTHER DATA ITEM: 0

Caution

Because monitor file definitions depend on the internal structure and data items of RTR, they may need to be changed for future versions of RTR.

A.2 Substitution Symbols

The text and labels in the DISPLAY commands that are used to define monitor pictures can contain symbols which are substituted when the picture is displayed. Table A–2 contains a list of these symbols.

Table A–2 Substitution symbols

Symbol Description

$TIME

$DATE

$NODE_NAME $LINK_NAME $FACILITY_NAME $PROCESS_ID $PROCESS_NAME $IMAGE_NAME

$FULL_IMAGE_NAME

Current time

Current date

Name of node where values were measured Name of link for which values were measured Name of facility for which value was measured ID of process for which value was measured Name of process for which value was measured

Image file name of process for which value was measured

The full file specification of the image for the process for which values were measured

The field width for these predefined symbols can be specified by appending a colon (":") and then the required width. For example, $TIME displays the current system time in the form "10:34:03", $TIME:5 displays the first five characters of the system time, in this case, "10:34". If the field width specified is larger than the field, then the data is left justified and space filled to the required width.

A.3 Arithmetic Expressions and Operators

When using data items and constants as parameters for display commands, or as Booleans in the BELL, BLANK, BLINK, BOLD, SELECT, REVERSE and UNDERLINE qualifiers, you may use the operators shown in Table A–3.
