Veeam B&R and Veeam ONE are integrated by default, right after you start working with Veeam ONE. Integration is done for monitoring backup activity and there are two things that would make your performance troubleshooting process much faster:
1. With Veeam ONE you have an ability to suppress any alarm that is triggered during Veeam B&R activity, snapshot creation and etc. In this case you will eliminate sending multiple alarms at the time when you have a scheduled backup window, thus your attention will not be drawn away from true problems and issues happening in virtual environment.
2. The second thing allows you to display all these types of events on performance charts: live migration, snapshot creation events, snapshot removal events and Veeam Backup events. This also comes handy when you're trying to pinpoint the root cause of the performance issue happened.
