The error occurs when Eco4Cloud virtual appliance does not obtain performance data from vCenter.
- Verify reachability from E4C vApp to vCenter.
- Verify network connection from E4C vApp to vCenter.
- Verify ecocloud user permissions on vCenter.
- Restart Host agent (restarting hostd, vpxa and ntpd deamons on host)
If the same error occours on VMware Infrastructure Client too probably the time is not synchronized between the VI Client host and the ESXi/ESX host so you have to restart the Network Time Protocol (NTP) as described in the following VMware Knowledge base.
