If you currently have no MAX RRA, you cannot recover that data. The consolidation process has already computed averages and stored those. > I am using RRDTOOL with an application called Spectrum Report Gateway > > Do I have to modify only the value of RRD:AVERAGE:0:5:288:797 to > RRD:MAX:0:5:288:797 in SRG.conf file and that's it?

If you have questions about tht SRG program, you probably should ask them (or a mailing list, or whatever they have). Maybe they have a script to add new RRAs to your RRD (such scripts do exist). What you really want to avoid is that you have to start all over again. I would not be surprised if such a program will create a new database when it notices an incompatibility. On the other hand, I would also not be surprised if it does not create a new database unless you manually remove the old one. If you can change AVERAGE into MAX in the RRD, it will *seem* as if you suddenly have a year's worth of maxima, but in reality this is not the case. Any new data will be true maxima.
