Hello, Recently after some investigation after some queries about the MRTG logs I have discovered that over time data gets summarized/averaged. The main reasons I can see for this are to maintain manageable sized log files and that each graph requires a particular amount of data to be generated. I am sure it is documented somewhere, but I have not been able to find out the exact reasons. After looking into the RRD tool and the tutorials I came across this snippet of information about the MRTG logs. I found it in the First Steps Tutorial for the RRD tool by Alex van den Bogaerdt http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/tutorial/rrdtutorial.html under the heading of "A Real World Example" it discusses MRTG logs 600 5-minute samples: 2 days and 2 hours 600 30-minute samples: 12.5 days 600 2-hour samples: 50 days 732 1-day samples: 732 days
All this is very interesting. But I need to be able to generate graphs on demand for any period down to a 5 minute interval. I have read the documentation on RRD, but it is still not clear to me if on using mrtg and RRD together I would be able to generate daily graphs for any period in the past. Could someone give me a definitive answer.
