Find the missing VMs and Hosts - VMWare
After the vcenter discovery if the VMs and Hosts are missing, query the below table and check
select * from vwentitymomapping where entity_type = 'VirtualMachine';
select * from vwentitymomapping where entity_type = 'HostSystem';
When the MOID is -4, check whether their DNS resolves, if not update it from vsphere client > host property
When the MOID is -5, that's marked as "deleted by user" so opmanager won't be mapping it.
We have run this update query manually and restart opmanager service.
update vwentitymomapping set moid = -4 where moid = -5;
Now automatic discovery will initiate during every restart.
