Cluster memory - Top 5 Performance and Capacity concerns for VMware

Continuing with VMware memory the next place to look at for memory issues is at the Cluster.

It is useful to look at:

–      Average memory usage of total memory available

–      Average amount of memory used by memory control

–      Average memory shared across the VM’s

–      Average swap space in use

In the graph below we can see that when the shared memory drops the individual memory usage increases. 

In addition to that swapping and memory control increased at the same time.

If it isn’t memory that people are talking to us about then it is storage. I'll be looking at number 4 of the Top 5 performance and capacity concerns for VMware on Friday when we take a look at Storage latency.
