Hi,

Short answer: probably not.

Long answer: you can, because it's all based on rrdtool. Observium itself is not actually tampering directly with the RRD files.

So, first of all: AFAIK this is NOT an officially supported solution.

Your config.php file can be tweaked with the variable

$config['rrd']['rra']

For defaults, have a look at includes/defaults.inc.php (search for $config['rrd'])

You may then define your RRA as you wish (this site may help out https://eccentric.one/misc/rrdcalc.html)

Note that even if you change the RRA definition, it will only apply to newly created RRD files.

You may try converting your RRD files with rrdtool if you want to backport previous data.

Else, simply deleting the RRD files will force Observium to recreate the files with the new RRA definition.

I can confirm this actually works well, given you understand RRD files and what the consequences of those changes are. YMMV.

Reminder: the solution above may break things. Make sure you understand what you do.

HTH,

Ahmed.

Dears, good morning!

Is there any way to keep the graphics detailed longer?
What I want is to keep the 5 minute histories, for example, for 6 months.

Thank you very much
