Monitoring provides resource and performance visibility so that you can make sure your virtual machines support your applications. When there are issues with application performance, you have extra visibility to increase or decrease virtual machine resources to optimize performance.

Reports usage trends

Analyses trends for discrete time periods

Monitors performance

Provides troubleshooting
