With On-Premise SharePoint 2013, we really have 4 channels for monitoring: Central Admin reports, ULS, powershell cmdlets for monitoring and finally SCOM.
None of these seems available with SPO. So as a SP Admin, what can i do for performing preventative monitoring and what tools do Misrosoft offer?
Understand that monitoring things like % CPU usage or DDisk IO are not relevant for SPO because that is handled by Microsoft. However, is there any alerting/notification mechanism for things like service degradation, planned maintenance, performance degradation, number of hits per site collection, hits per page, cache hits/miss, etc?
