Performance Analysis: - CPU usage consistently high - VM CPU usage >90% - CPU Ready > 20%
insufficient host resources - CPU, storage, network
58
Performance Analysis: - Host memory >94% - VM swapping is occurring
insufficient host memory
59
Performance Analysis: - VM memory usage is high - Guest OS memory usage is high - Paging occurring
Guest OS doesn't have enough memory available
60
Performance Analysis: - VM CPU ready is low - Guest OS CPU utilization is high
Guest not provided enough CPU
61
Performance Analysis: Datastore space utilization is high
- snapshot files - overprovisioning VMs - small datastore
62
Performance Analysis: Dev latency >15ms
problems on storage array
63
Performance Analysis: Disk : - VMkernel latency is >4ms - Queue latency > 0
maximum throughput of a storage device is not sufficient to meet the demand
64
Performance Analysis: Network: - dropped packets > 0 - latency is high - transfer rate is low
max throughput of network is insufficient
