If you want to know how often google hits your pages per <time interval of your choice> then RRDtool is the right tool for you. And that's simple. Every <possibly other time interval> you come up with a number of queries during that interval. Your application has to make sure it knows when it was called last, forget every log entry upto that time, count the number of interesting log entries and output it. Then you give the number to RRDtool, using ABSOLUTE. This produces a rate, pages per second. ABSOLUTE is a counter that is reset every time it is read. This is what your program should do. But ABSOLUTE does take the time into account. This is what RRDtool should process. Update as often as you want. For instance, every hour. Most rates will be zero, so what. That is useful information. In the database you have pages per second. Multiply this (using CDEF) by an amount to get pages per hour, or pages per week, or pages per minute. Just remember that everything is a rate. If you are using GAUGE, you are inputting a rate yourself. If you are using any other Data Source type, you ask rrdtool to process its input to generate a rate. And do make sure you understand normalization and consolidation. -- Alex van den Bogaerdt http://www.vandenbogaerdt.nl/rrdtool/ -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
