This one is a quick and dirty, just to help those who are trying to push the Telegraf agent from the vROPS / Aria Operations UI but are getting an error. This is likely because the account doesn’t have passwordless sudo so lets set this up!
Create the following file if missing /etc/sudoers.d/vmware-arc and add the following content.
Defaults:arcuser !requiretty Cmnd_Alias VAPCOMMANDS=/usr/bin/systemctl * ucp-telegraf.service, !/usr/bin/sys> arcuser ALL=(ALL) NOPASSWD: VAPCOMMANDS
Update the permissions on the file with the following command
sudo chmod 440 /etc/sudoers.d/vmware-arc
Then try to deploy the agent again via the UI.
Hope this was helpful
