Our monitoring tool is reporting high memory usage on a MDS 9124e switch.
The used memory percentage exeeds 90% all the time, for the last couple of months.
Most of the time the usage is around 95%. CPU usage however, never exeeds 10%.
The same statistics are shown when the command show system resources is executed.
NX-OS version 5.0(4)
Is this normal behaviour? Please advice..
Solved! Go to Solution.

Oops sorry I meant Show system internal memory-status. This will tell you if you have currently reached the memory threshold. If it says Memstatus:ok and your monitoring software shows 95% in use it is probably the CSCtn66877 bug.

Hi,
Have you tried running "show processes memory"? This will give you a breakdown of the memory usage.

Well I did. But i don't know whether or not these numbers are ok.
