DSM Management Tools and Performance
Measuring Tools
•
Testing user-generated EMS events; you can display all tokens in a message, thus
verifying the correctness of events generated by the business application
For complete details about EMS Analyzer, refer to the Event Management Service
(EMS) Analyzer User’s Guide and Reference Manual.
EMS FastStart
EMS FastStart provides a simple, cost-effective way for programmers to develop and
test EMS event messages and to add event-message generation to an application.
You do not have to build EMS tokenized event messages. Instead, you can generate
events as application-level messages that are converted into EMS messages for you.
A more detailed overview is given in Using EMS FastStart to Generate Events on
page 8-26.
For full details on using EMS FastStart, refer to the EMS FastStart Manual.
Guardian Performance Analyzer (GPA)
GPA gathers performance data from Measure and then analyzes the collected data.
The analysis produces a summary report from which you can move to more detailed
analyses. GPA also supplies recommendations for corrective action when performance
is poor and provides a set of command files to carry out its recommendations. GPA
can report on any object, subsystem, or application for which Measure provides data.
You can use GPA on a regular basis to locate areas in a network where performance
might become a problem. Once problem areas are located, you can use GPA to
recommend corrections to be made before performance problems affect availability.
For complete details about GPA, refer to the Guardian Performance Analyzer (GPA)
User’s Guide and Reference Manual.
Network Statistics Extended (NSX)
NSX is a network performance monitor that collects and displays processor, process,
and Expand process statistics from other NonStop systems operating in an HP
network.
NSX monitors and reports high-level, real-time network statistics from multiple network
nodes to one or more locations within that network. In addition, NSX collects and
reports on the busiest processes in each processor in all monitored systems.
For complete details about NSX, refer to the Network Statistics Extended (NSX)
Manual.
Object Monitoring Facility (OMF)
OMF allows you to supervise objects such as processors, disks, files, and processes
within your HP subsystems or applications. OMF monitors objects for peripherals or
subsystems, according to the object configuration stored in and maintained by OMF.
