Troubleshooting performance issues
You can check DDVE performance statistics as follows:
- By monitoring the collection of diagnostics data using metrics in the Azure portal. How to monitor virtual machines in Azure provides more detailed information.
You can also use the following to monitor benchmark performance:
- perf
Extensions to DDOS for DDVE provides more information about commands.
CPU Performance
The two key statistics for CPU performance are:
- CPU usage—CPU usage as a percentage during the interval
- CPU ready—The percentage of time that the virtual machine was ready, but could not get scheduled to run on the physical CPU. This counter might not be displayed by default.
If these counters are high, there may be a performance problem on the hypervisor host.
Memory Performance
- Memory swapping—The key statistic for memory performance, which is the current amount of guest physical memory swapped out to the virtual machine’s swap file.
Virtual Disk Performance
The key statistics for virtual disk performance are:
- I/O throughput—A decrease in these values indicates a performance issue.
- I/O latency—An increase in read and write latency values indicates a performance problem.
