It is possible with RRDTool. When you create your RRD initially, you'll either need to do it by hand or modify cfgmaker to store however many 5 minute points you want. We do this today, but the size of the RRD will grow significantly (roughly 300 times as large as the default RRD).
If you want about a year's worth of 5 minute data points, you'll need to specify 288 x 400 = 115200. Just to be safe, this way you'll store a little more than you need, but it should get what you are looking for. 288 samples per day (in 5 minute increments) 400 days' worth in the RRA 115,200 samples for 400 days' worth of 5 minute data. Just modify mrtg in the area where the RRD is created. That would be the easiest. Then you automatically create every RRD with a 5 minute RRA of the size you want. Paul >>> "Simon Hall" <[EMAIL PROTECTED]> 07/17/03 06:54AM >>> 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.
