Hi

The server is running a Linux OS and is being probed with SNMP. I receive many alerts where the server is at 97% utilization and when using the free command the free mem is 24MB but the majority of this is being used by the OS to buffer disk IO.The actual memory available is 3482MB.See below.

             total       used       free     shared    buffers     cached

Mem:          3951       3927         24          0          4       3453

-/+ buffers/cache:        469       3482

Swap:          509          0        509

Please advise how the probe can be adjusted to use the free command to show the actual memory.

Thank You.
