Prem, I used Orca to produce an Oracle performance recording tool ( http://www.hoopoes.com/cs/orca/ ). Orca does all the heavy lifting; my piece extracts data from Statspack/AWR into the space-separated format needed. This is all Open Source, so you are free to re-use for your situation. RRDTool is at the heart of Orca, and is great if you are satisfied with the long-term diminuition of precision necessary to keep datasets to a fixed size. It does allow you to keep long term trend records whilst disposing of old data from your database in a sensible fashion. If the data is something you expect to keep in an Oracle database, then Perl's DBI would be my tool of choice, but that's because I already know how to use it :-). Cheers, Duncan. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Prem Khanna J Sent: 02 December 2008 10:32 To: tanel@xxxxxxxxxx; oracle-l@xxxxxxxxxxxxx Subject: Re: making graphical reports from oracle metrics Guys , Thanks a ton for all your valuable replies .
