Since I have to benchmark an algorithm I have installed cacti to monitor one machine. I wanted to disable the default RRA since I need all the raw data, so I tried to set up a Data Profile that does not make any round robin for one year:
I saved the profile and I set all the data sources to match it in Template > Data Sources > Select All > Action = Change Profile > Go.
I also set up the cron job to run every 30 seconds and I updated the main settings to match the poll interval. Everything seemed to work. The problem is that if I access to data that is older that about 12 hours, I only have samples that are taken every 15 minutes instead of every 30 seconds! I noticed this when I tried to go backward in time in the Graphs tab I get the following.
Last 6 hours:
<< 6 hours:
<< 6 hours:
<< 6 hours [now I have 15 minutes samples]
Thanks to anyone can help me.

Really thank you! Now all the data is preserved.tertius wrote:You have to delete existing *.rra files for these data sources and let Cacti create new *.rra files with the specification from the new profile. Cacti isn't able to change the properties of existing *.rra.
