vCenter connection lost

Mathias_Robichon — Thu, 05 Jun 2025 06:05:44 GMT

Hi folk,

During a POC Balance, we encounter a problem. The infrastructure is made up of 2 vCenter servers with the same configuration (from memory, one is vSphere 4.1u1 and the second 4.1u2).

The first one is working well. The second loses regulary the connexion during the gathering process. You are able to see the end og the logs file here :

The full file is enclosed.

The errors SEVERE No valid hostname was found for this VM : 0199412368-AMETIFFAX01 are normal" because the VMs aren't is the same DNS domain. We got several. The last line is the problem.

Anybody has any hints ?

Mathias

Hi Mathias,

In looking at the log file you sent and talking to engineering this is usually caused by the vCenter server closing our connection. Do you know if this vCenter server in question is under-provisioned? If there aren't proper resources on the end device our collections may fail.

Thanks, Daniel

Hi thanks a lot for your reply,

The vCenter server is loaded. Also, vmware reports a bug with the UI on port 443 when a lot of objects are configured. So, I guess that Balance uses port 443 with API and not the UI. Anybody could confirm that ?

If Balance uses only API, it could confirm a load problem with the vCenter.

Thanks a lot.

Mathias

Hi Mathias,

You are correct. Balance is talking to vCenter using API calls.

Let me know if you have any other questions.

Thanks, Daniel
