High RAM Usage on Peplink SDX Pro

I have a Peplink SDX Pro running with a KVM. I have only allocated 2Gb of the 7Gb I have available. My SNMP monitoring service is detecting my RAM usages is at 90% regardless of the KVM running. I can not find anywhere in the Web UI that can show me RAM utilization. Any insight would be great help. Firmware: 8.2.1 build 5375
