How can I determine the performance impact of changing my vCenter statistics level from 1 to 2? I don't want vCenter to go down or start running at an unacceptable performance level, however for long-term performance monitoring I would like to be at level 2 rather than 1.
It will obviously impact on your database performance and also functionality of vcenter as there are more metrics collected at all intervals and this generates a lot of data. But level 2 is not that bad. Do check the growth size and whether you will be able to accommodate the growth. I think level 3 and 4 are the ones which will cause more impact.
