Telegraf Agent Related Actions Fail after Cloud Proxy is Restarted or Upgraded

Problem

After an upgrade of vRealize Operations/vRealize Operations Cloud and cloud proxy from 8.4 to a later releases or if you restart cloud proxy, Telegraf agent management related actions could fail with the error message Connect to Salt Master.

Cause

The saltmaster docker container inside cloud proxy does not run properly causing all Telegraf related actions to fail.

Solution

1. SSH to the cloud proxy VM.
2. Verify if the salt process count by command is: ps -ef | grep salt.
3. If the salt process count is less than 15, run the following command: /rpm-content/ucp/subsequentboot.sh.
   You can view the log from the following location: /opt/vmware/var/log/ucp-subsequentboot.
