Just curious, what is the business reason to develop such a tool when there are zillions of them available ??
mild advice/recommendation
before writing Your own performance monitoring tool, learn to use and understand the existing ones ( RMF for example ) |

| This is a very ambitious project. There's a lot to z/OS and depending on how detailed you're wanting to get, a tremendous amount of work is required to analyze system performance. You'd want to start by understanding the SMF record types, so find the SMF manual and read it thoroughly to understand them. |

Who provided the requirement? What is the scope of the requirement. Do you need to look at things that "have happened" or things that "are happening"? What sort of output is required?
How strong are you in assembler? How familar with operating system internals are you (i.e. control blocks, processes, SMF record formats/content etc)?
Robert makes a very good point. . .

And i believe, starting with part of the smf data will be to your advantage before jumping into real-time. |

| I agree, I had been to such a requirement once (& I said a big NO) and I'm pretty much sure this is not a client requirement at all; just some PM must have come up with such a "garbage" idea, just to show he can "think"... |

| Suggest that your site purchases SAS & MXG and save yourself years of heartache. |
