RTR Monitoring

This chapter contains a description of the RTR monitor. The RTR monitor gives you a means of viewing the activities of RTR and your applications. Many different aspects of RTR's behaviour can be viewed, allowing the activities and performance of RTR to be analyzed.

5.1 Introduction

The RTR monitor provides a means to continuously display the status of RTR and the applications using it.

It can be used to check the correct operation of an RTR network, showing information useful for tuning, capacity planning, and locating configuration and application errors.

The information displayed is composed of named data items which are continuously updated by RTR. These data items can be displayed in various formats, and combined using simple arithmetic operators and constants.

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.

You can use monitor files that are provided with RTR, and you can create your own. See Appendix A for information about creating monitor files.

5.2 Standard Monitor Pictures

A number of standard monitor pictures are supplied with RTR. These cover most of the usual monitoring requirements. You may define your own monitor pictures or alter the standard ones to suit your particular needs. Table 5–1 contains a list of the standard monitor pictures. To display one of these pictures use the following command at the RTR prompt:

RTR> MONITOR picture-name

The files for standard monitor pictures are installed on your system when RTR is installed. The location of these files is platform-specific. The filenames are the picture name appended with .mon (You type the filename without .mon when starting the display.)
