Hello pdighade,

that tpm value I need to calculate .. Please help me with logic as soon as possible |
You insist on non-standard terminology and then want it asap. . .
Please consider that if the best 2 of us were on-site and available to implement the requirement definition, we could do little. . . So far, there is no usable description/definition ("tpm" is not effectively communicating). You believe there is something easily attainable (and it probably is easily obtainable) and most likely something that many of us have done multiple ways. To you the requirement is obvious. Unfortunately it has not been clear to the people would help if they could.
As Pedro requested you need to post the "output" you want from 20 real records. Make sure these sample records cover all cases you want reported. |

you say it is for performance measurement...
I question why you are checking in 10 second or even 1 minute intervals. Say you have good performance all day, but real bad performance in only one 10 second interval. What will you do? I do not think you can tune your system so quickly. |

Your claim is that you are doing performance management, but you seem to be doing things in ways that are not standard to the industry. Have you looked at what the Computer Measurement Group provides as a guide to industry practices? What background do you have in computer performance measurement? Have you considered using your site's WLM data as a starting point rather than creating your own statistics and thus reinventing the wheel?
Using 10-second intervals is ludicrous -- that gives you 8,640 intervals per day, or 2,880 per shift. There is no way you can meaningfully do any kind of tuning on that number of intervals. 15-minute or 30-minute intervals are more commonly used and at least meaningful tuning can be done with that interval size. |

Hello,
The length of the interval is only one part of the equation. Even with a 10-minute "interval", there will be thousands and thousands of "interval overlaps".
You still need to determine the "rules" and post them.
As i mentioned earlier, what i believe you want to do is not difficult. . . It merely needs to be specified clearly.
Now is surely a good time to generate some representative "output" from a set of realistic sample data. |
