Most enterprises use RHEL/CentOS because of the long, stable lifecycle compared to other distros...
but, it indeed looks like there was a net-snmp bug -- I just updated net-snmp-5.7.2-43-el7 and Observium is happy! So I'm assuming there was Observium code to fudge with the incorrect data returned from older EL7 net-snmp versions?... ugh :(

Thanks,

This was caused by a fix for RHEL 8 having different memory reporting style to RHEL 7.
It seems the fix was a bit too enthusiastic, as predicted.
If everyone stopped using RHEL, we wouldn't have these issues, though...

I'm seeing this issue as well after updating to 19.10.10148, all my memory graphs went from low values to 90%+ mempool_perc. Is there a fix? For now, I updated my memory alert checks to be mempool_perc > 100 to disable the false alarms.
Thanks,

Hello all,
I have a Red Head Enterprise Linux 7 Device for which the Free Memory is calculated wrong. (I think) All worked fine until 3 Weeks ago, now I get a wrong free memory value.
The poller Module for Memopools reads:
