You can change this BUT you will need to delete and re-create all your RRDs which means you will lose all your data.
If you just want higher accuracy and save the high-resolution measurements for a longer period than 7 days you can set this in your config.php: $config['rrd']['rra'] = $config['rrd']['rra_300']['accurate']; This will save the measurements for 93 days before downsampling it at the cost of disk space of course and you will still need to delete all your current RRDs for this to take effect.
If you want to save data for more than 4 years you will need to edit the RRA-values, this is a bit more complicated and requires you to understand the RRD format. You can find the defaults in observium/includes/defaults.inc.php at line 130 You will need to create a new array with your new values and then set that as $config['rrd']['rra'] and then delete your RRD-files for it to take effect.

Hi Everyone,
Running Observium CE 23.1.12493, noted that observium keeps 4 years, 1 day of data, as per the faq, https://docs.observium.org/faq/
Is there a way to change this, I only run 10 devices and im happy to scale up the disk and cpu / ram ?
Regards,
