          please attach additional debug (I need to see UCD-SNMP-MIB::version*):

          ./discovery.php -d -m mempools -h <device>

          I fully agree with Olorin's comment above. Our CentOS 7 systems updated this week started showing funky memory graphs. Observium version 20.4.10371.

          All was fine with net-snmp-1:5.7.2-43. Upgrading to net-snmp-1:5.7.2-48 caused the issue.

          RHEL/CentOS have now reversed this behaviour, so the graphs again aren't calculated properly. Can we undo this patch?
