When no performance data is available on a single host, restart the hostd and vpxa services

From the Local Console or SSH:

1. Log in to SSH or Local console as root.
2. Run these commands:/etc/init.d/hostd restart
   /etc/init.d/vpxa restart

   Note: In ESXi 4.x, run this command to restart the vpxa agent:

   /etc/opt/init.d/vmware-vpxa restart

3. Alternatively, to restart all management agents on the host, run the command:services.sh restart
