Hi @Marc_Boisis
LibreNMS will regenerate them after next poll. So you don’t have anything to do.

Hi,
the poller does not recreate the file :

poller.php -h 19 -v
…

#### Load poller module mempools ####

It does when rrdcached is configured properly or when rrdcached is not installed at all. Seems that your rrdcached is broken.
You should check the docs and fix it.

It works, I forgot
$config[‘rrdtool_version’] = ‘1.7.2’;
thanks
