In ESXi 5.1 all of the online instructions I can find indicate that the root user has to be used to poll wsman in OpenManage Essentials. Why does monitoring require maximum priveleges? Does anyone have a custom role in vcenter that can accomodate everything that wsman would need?
Thanks for your post. OME currently only supports root account for WS-MAN communication with ESXi servers. We'll let marketing know about the ask and can look into supporting read only account for future releases.
As a work around you can use the mechanism suggested in the thread below:
Any updates on this? I'm rolling it out and I'd really like to not use an account with root priveleges. I tried the setup in the post you linked, but in my 5.5 environment I don't have a root group and a read-only permission seems to produce an 'unknown' health status. If I change my ws-man configuration to the root account the health status changes to 'Healthy'.
