Applicability
RPM is a universally applicable operations tool for NonStop servers. It is designed to do
one thing very well, that is real-time monitoring, discovery, and display of the busiest Cpus
and processes executing in one or more NonStop servers. The RPM product can be used
by a wide-range of systems, devices, and operations personnel. RPM capabilities include:
Multi-node, multi-operating-system, multi-device aware
Applicable regardless of what products or applications you are running
Supports J-, H-, G-, D-, series operating systems
Supports mixed-version hardware/software networks
RPM is highly customizable, it can support both small and super-scalar devices
with screen sizes ranging from 12” 80x24 x 1-Cpu to 84” 200x300 x 1000-Cpus
Supports multi-device types TTY, T6530, VT100, and output to disk files
Provides real-time cluster monitoring capabilities that do not otherwise exist
Built based on long-term development experience and the requirement to
understand real-time dynamics of software in network clusters
RPM is a proven software development and operations utility that has
been evolved and refined over a multi-year period in HP Labs
1.3. Architecture
NonStop RPM consists of two functional components packaged together into one object
file which is the RPM object file. The RPM object file acts as both a command interpreter
user interface and also as a real-time Cpu and process monitor. To run RPM you simply
run RPM from a TACL prompt. RPM utilizes peer-to-peer messaging capabilities that are
unique to NonStop servers.
There are three versions of the NonStop RPM command interpreter (CI)
RPM - Object file for TTY devices. This CI runs in TTY mode, displaying real-time
Cpu and process information without embedding color-encoding or screen positioning
information.
RPMVT - Object file for ANSI or VT100 devices/emulators. The RPMVT command
interpreter runs in VT100 mode, displaying data with color-encoded and screen
positioning information embedded in the I/O stream that is compatible with ANSI or
VT100 devices.
RPM65 - Object file for T6530 devices/emulators. The RPM65 command interpreter
runs in T6530 mode, displaying data with color-encoded and screen positioning
information embedded in the I/O stream that is compatible with T6530 devices.
