Sorry for the double post. After reading the email several more times, I realized it doesn't make much sense.
I am looking to create an RRD with a 3-month and a 5-year archive. I have a counter which is retrieved and reset every 30-minutes. The data needs to be accurate for the 5-year archive and not an average. I would like to keep the file size to a minimum (ie not store 30-min records for 5 years). Perhaps the best way to explain is with a sample. rrdtool create file.rrd --step 1800 \ DS:30min:ABSOLUTE:3600:0:U \ DS:10hour:(take last 20 30min PDP's and total them) \ RRA:LAST:0:1:4320 I would prefer to use something like COMPUTE for 10hour (don't know if this is possible). However, as a last resort I could possibly cache the PDPs in the script I'm using then update 10hour with their total. In which case would something like the following make sense? rrdtool create file.rrd --step 1800 \ DS:30min:ABSOLUTE:3600:0:U \ DS:10hour:ABSOLUTE:72000:0:U RRA:LAST:0:1:4320 Thanks again.
