There is no UEMCLI or Unispher method for determining the System memory usage on the array. It's all used for the OS running. You can SSH to the SP and run TOP to see what processes are running.  glen
We have a monitoring tool in place and we are receiving this alert almost every hour from Unity 350F. Could you please help me in how to check the memory usage using Unisphere or UniCLI.  I have tried to check on the Unisphere but could find the options to check the Cache memory size.
