Incorrect value for disk/memory shown for linux

Incorrect value for disk/memory shown for linux

Hi, Im very new to ops manager + and i feel i have probably missed something obvious, however, I would deeply appreciate your assistance.

We have installed snmpd on around 120 linux servers, but it is not always picking up the right values example


Actual usage

/dev/mapper/VolGroup00-LVvar        63G  6.2G   54G  11% /var

yet the monitors all report it as 96% used

Similar issues lie with memory, claims 99% used when out of 754gb it has 425gb free.

for now, ive deleted the memory monitors, but, we really do need them to work
