Data upload to vCloud Usage Insight fails intermittently

Products

• VMware Aria Suite

Issue/Introduction

Symptoms:
Upload to vCloud Usage Insight fails intermittently with notification and collection errors. A connection test from vCloud Usage Meter to vCloud Usage Insight as per KB article 82023 works fine.

However, the following HTTPS connectivity check to vCloud Usage Insight

openssl s_client -connect ums.cloud.vmware.com:443 -servername ums.cloud.vmware.com  

throws this error:

getaddrinfo: Name or service not known
connect:errno=0

Environment

VMware vCloud Usage Meter 4.x

Cause

The cause for this issue is that multiple DNS servers are used, leading to the ums.cloud.vmware.com address not being resolved.

Resolution

Update /etc/systemd/resolved.conf and remove any additional DNS entries.

Procedure

To solve the upload issue, do the following:

1. SSH to the Usage Meter appliance as usagemeter.
2. Switch to the root account:

sudo root

3. Back up the resolved.conf  located at /etc/systemd  by running the command:

cp /etc/systemd/resolved.conf /etc/systemd/resolved.conf.bak

4. Open the resolved.conf file.

vi resolved.conf

5. Type i to switch into insert mode and start editing the file.
6. Modify the /etc/systemd/resolved.conf to remove the second DNS entry.
7. Save your changes and exit the vi editor.

:wq!

Note: If you don't want to save your changes, enter :q! to exit the editor.

8. Reboot the appliance.

reboot

Additional Information

If you are using a .local domain, it will be worth updating the Domains field in the resolved.conf file as per KB article 83945.
