Re: how to monitor memory usage on freebsd systems

Thank you Dave

Yes, the hw.physmem makes sense.
That's not the issue.

The issue is hrStorageUsed does not make sense.
It is much greater than the value calculated from sysctl -a.

Thank you Michael.

Sysctl shows that only 181MB (35%) of the physical RAM is used.

The hrStorageUsed figue is  1172379 x 4096 ~= 469MB (91%) is used.

I am very sure the memory used is not 91% as there isn't much running on the
server.

This discrepancy also happens on other servers, i.e.,. the snmp
hrStorageUsed figures
for Physical and Real memory are much higher than the Sysctl's figures.

Something is not right with net-snmp implementation for freebsd?
/usr/ports/net-mgmt/net-snmp/
work/net-snmp-5.4.1.2/agent/mibgroup/hardware/memory/memory_freebsd.c
