GIAPA by iPerformance
GiAPA (Global i Application Performance Analyzer)
GiAPA is an Application Performance Analysis and Operations Support Tool collecting comprehensive resource usage information 24/7 for all jobs every 15 seconds using less than 0.1 % CPU. The data is analyzed automatically obviating the need for expensive external consultants and the resulting data base permits generation of a large number of standard and user defined reports and charts.
Development and Programming
The team responsible for producing efficient program code. GiAPA turns programmers into "Performance Experts" by pinpointing exactly where resources are being used, down to source statement line number.
With GiAPA on board development can run a performance quality control of new programs before they are moved to production.
In addition, GiAPA's unique analysis of file access often reveals significant optimization potential even for jobs assumed to run efficiently.
The team responsible for monitoring the everyday use of server resources. GiAPA can amongst others enable operators to:
- find the reason for performance problems even after they occured
- spot any misuse of machine resources
- react immediately if a job starts looping
- check who is running which queries, when and for how long
- get statistics for any resource usage by user, application, etc.
- compare workloads., e.g. before/after diagrams when new program versions are installed
Require high-level information on how IT resources are used, ideally charts providing full overview "at a glance".
This is exactly what GiAPA's extensive graphical features were designed to produce. The possibilities include "Good morning reports", usage or trend analysis per LPAR, department, application, etc.
Even user defined graphics are available. Example: Is the increased resource usage by application XYZ justified by a corresponding growth in number of transactions?
