VMware Monitoring - what to watch out for
- When any VM has a CPU Ready time of over 20% and the host CPU utilization is also over 90%, it signals CPU overcommitment & would need addition of CPU or VMotion enabling
- More than 1MB/s of swap in or swap out rate signals memory overcommitment
- From an EMA benchmark report, average performing enterprises had physical CPU utilization of 45% while best performing enterprises had this at 70%. Where do you stand?
