I have to store each request data to rrd database. the request granularity can be more or less than one million hits per second. can rrd support granularity in milli/micro seconds.
Based on your email, there seems to be no need for milli/micro resolution, unless you're doing ADC sampling or something similar, which you are not.
1) How much time the request takes on average for each: minute, hour, work day (6am-8pm), day (24 hour), week, month That's not a million per second, is it?yes it is not million request for the above required report. but i have records of requests that hit my site that may be million.
No, not a million per second; simply many records you have to analyze.
4) Number of requests in each ÿÿperformance groupÿÿ. For example, how many requests are 0-100ms, 101-200ms, 201-300ms, 301-400ms, 401-500ms, etc ...

5) When am I having requests > 1000ms? < 5000ms? What is associated with these? Certain times of day? Certain traffic volumes?
My requirements are given below.
That's asking a lot, is it not? :-) An intelligent Perl or VS C# app (for Excel integration, as you mentioned) may be more beneficial for you there.
