Creating Monitor Pictures

The standard monitor pictures provided with RTR (described in Chapter 5) are sufficient for most needs. You may also create your own monitor pictures to suit particular needs. This appendix tells you how to do this.

The RTR monitor utility provides a means to continuously display the status of RTR and the applications using it. The information displayed is composed of named data items which are continuously updated by RTR. The data items can be displayed in various formats, and combined using simple arithmetic operators and constants.

Note that in earlier versions of RTR, the data items were known as counters, and only contained numeric information. The name has been changed to indicate that string data may also be retrieved.

All RTR data items are associated with an information class. When entering a data item in a display command, it may be prefixed with a string to indicate which class it belongs to. This can speed up the processing of monitor commands. Information classes are shown in Table A–1.

Table A–1 Information Classes

Information Class	String
per node	"rtr"
per facility	"fac"
per link to a node	"lnk"
per client process	"cli"
per server process	"srv"
per application process	"prc"
per partition on a router	"rpt"
per partition on a backend	"bpt"
per key segment	"ksg"
per transaction on a frontend	"ftx"
per transaction on a router	"rtx"
per transaction on a backend	"btx"

The monitor is invoked with the RTR MONITOR command. RTR monitor displays a monitor picture that is periodically updated. See Section 6.2 for the full syntax of the MONITOR command.

A monitor picture contains elements that are either text (such as labels and titles) or variables derived from data items. Monitor pictures can be defined either interactively at the RTR> prompt or defined in a file called a monitor file.
