Hi Experts,
What this total memory and used memory signify in this output. Is this shows that around 97 percentage of usage from the current memory allocated to the VM ?

Hi Manish,
You see these high values because of the way Linux works. When the Linux system is not under memory pressure, all of the kernels caches will slowly grow over time. Linux prefers to keep larger caches just in case someone needs information in the cache. After all, there is no reason to return cachememory if no one really needs it. This cache memory is readily available when any process needs more memory.

Manish,
The link you posted doesn't work. Can you post an updated link please?
I've got a customer asking me about the same thing on their cluster and rather than just going back to them and saying "it's nothing to worry about" it would be good if I could send them a link to a Cisco doc but I haven't been able to find one.
Thanks,
Vincent

Do you have a substitute link?
Thanks.
