Introduction

The reporting facility allows the user to examine historical data in On-line Playback Mode and to download report files into spreadsheet applications. SPS also features a system wide Analyze System Server process that reduces the overhead associated with the analyze_system subsystem and allows users to extract periodically and log any set of benchmark values.

SPS produces alert signals and automatically executes corrective commands when any of the monitored meters exceed the allowed thresholds.

How tall is your application?

You can meet these objectives SPS/Performance:

	Determine the performance characteristics of my application
	Determine the maximum user load capacity
	Demonstrate application and system scalability
	Demonstrate the application meets the performance requirements
	Determine application and system break point
	Determine if the current infrastructure can support the application
	Ensure that the infrastructure configuration meets requirements
	Ensure that the system operate at with tolerable response times at peak hours
	Ensure that the system can sustain predefined throughput
	Ensure that the system is optimally configured for performance
	Evaluate impact of application on current infrastructure
	Understand system behavior with different transaction mix
	Pinpoint and remove application and system bottlenecks
	Know you limits and prepare for future capacities

Features

	Records system utilization meters: CPU utilization, page faulting time and rate, disk I/O and system interrupt rates
	Monitors transaction rate and identifies processing bottlenecks
	Analyzes historical data (hourly, daily, weekly and monthly) and creates spreadsheet-ready, ASCII report files that can be imported into any customer chosen spreadsheet application such as EXCEL
	Monitors application queuing activity, messages processed, messages pending, queuing rate and queue depth
	Features a real-time, graphical view of all monitored modules
	Provides process listings (list_users) sorted by: CPU utilization, I/O rate, Page faults and Interrupt rates
	Supports multi-module, multi-system sites
	Provides a Playback Mode for historical data analysis
	Provides monitoring and alerting functions using any user-defined meters from within analyze_system
	Allows threshold and alert settings for all monitored meters

Frequently asked questions

1. What kind of system overhead should I expect?

   None. The SPS server wakes up every five minutes only to take a quick snapshot of system condition, it takes a few mil-seconds and then process continues to wait another five minutes for its next cycle.

2. Should we be concerned with VOS releases or versions?

   Not at all. SPS does not utilize any "secret" or undocumented system structures or system calls and is therefore completely independent of the VOS release level. SPS runs reliably on any VOS release (8-12).

3. Do I need to be a performance "guru" or take a course?

   Absolutely not! SPS is designed to be up and running and become useful in any production environment in minutes. Typical learning curve is 20 minutes.
