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

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:

is installed. The location of these files is platform-specific. The filenames are
