I am new to netmrg and must say that it looks great. Kudos to the developers! Now, my question
By default, the data collection in the cron job appears to be 5 minutes. If I change the sample rate from once every 5 minutes to once every minute, is there a way to change the default graph time axis to show this increased detail?
There's currently no way in the user interface to change the intervals displayed (other than in the advanced view). You can, however, customize the existing intervals in stat.php. It should also be possible (although I can't recall testing it) to add an arbitrary number of "timeframes" (as we're internally referring to them) by making modifications in this file. Good luck!
