Looking to compare latest NPM features with previous versions of NPM?
The NPM new feature summary offers a comparison of new features and improvements offered with this release.
This article describes the problem when ESXi hosts show status unknown. It is also unable to poll and VM's on ESXi hosts also display as unknown.
This issue occurs when in NPM virtualization settings, you poll through ESXi or vcenter while in VMAN appliance, you are polling through ESXi or vCenter. Both NPM and VMAN should poll through the same settings preferably vcenter with the same credentials applied.
