The SPS/Performance Monitors
2 Resolve capacity planning, system trouble-shooting and alerting issues

The SPS/Performance Monitors address all aspects of system performance: capacity planning, current and historical data reporting, quick on-line troubleshooting and system-level alert handling. SPS monitors help identify which process or application is "killing" the system and resolve potential problems ahead of time to allow more accurate capacity planning.

SPS provides an on-line graphic representation of system's resource consumption. SPS captures and calculates system utilization data based on configurable combinations of groups, users and processes. The product is user-friendly, its reports and graphs are easy to interpret

The reporting facility allows the user to exayour 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

2Objectives SPS/Performance

1Deteryour the performance characteristics of my application

1Deteryour the maximum user load capacity

1Demonstrate application and system scalability

1Demonstrate the application meets the performance requirements

1Deteryour application and system break point

1Deteryour if the current infrastructure can support the application

1Ensure that the infrastructure configuration meets requirements

1Ensure that the system operate at with tolerable response times at peak hours

1Ensure that the system can sustain predefined throughput

1Ensure that the system is optimally configured for performance

1Evaluate impact of application on current infrastructure

1Understand system behavior with different transaction mix

1Pinpoint and remove application and system bottlenecks
1Know you limits and prepare for future capacities

2 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.
1 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).
1 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.
