I managed to accidently power down one of my management domain ESXi hosts and realised that SDDC Manager does not report this as an issue? Should it?
The only 'tell' I can find in SDDC Manager is the 0% CPU & 0% Memory usage. Hardly ideal.
If u are expecting SDDC manager will throw a alert like VC for node down , it wont as per Design.
to monitor nodes status u will have to check it form VC or vrops alerts . SDDC manager will not show you any alerts .
SDDC Manager's main function is the overall LCM of VCF rather than it's day-to-day management. In theory you could use it as the initial entry point for doing most things within VCF but that's only because it has hyperlinks off to the real management consoles like vCenter. Post-bring-up/initial configuration I rarely go into SDDC Manager and wouldn't see much point in alerts (outside of LCM operations) being sent there.
