Only 1 month of data is stored

My librenms seems to only store last month of data, I do not use any cleanup options in config.php.

./validate.php output:

my config.php:

Any help appreciated, thanks.

What data do you mean?

The data that feeds the rrd graphs, I monitor around 20 machines, various applications on them and any and every single graph abruptly ends 1 month in history.

wonder if could be time sync related

Is this on your Raspberry Pi setup ? I dont think they have hardware clock (RTC).

Disk space OK?

yes this is on my rpi4 setup, but it shouldn’t be time related as I run my own ntp server on separate machine and all my other machines sync with it. Space shouldn’t be an issue either, the root system is on 120Gb ssd with 100Gb free.

The only thing I experimented with in config.php after initial install was purging the unused rrd’s after set period of time (I monitor several windows machines which like to rename the interfaces every other day which creates new rrd) via the $config[‘rrd_purge’] option, however the disk space gained was negligible so I removed it from config.php.
