We recommend using the root account for ESX monitoring. If the root account is not available, you can add an Uptime Infrastructure Monitor user with the following instructions: 

  1. SSH login to the ESX system as root.
  2. Create your Uptime Infrastructure Monitor user: > adduser –p PASSWORD uptime 
  3. Edit /etc/vmware/hostd/authorization.xml as shown below. You will need to: 
  4. Restart vmware-hostd: > /etc/init.d/mgmt-vmware stop > /etc/init.d/mgmt-vmware start 
  5. Wait about 5 minutes for hostd to restart. 
  6. Add your ESX system to Uptime Infrastructure Monitor.
