Followed all the steps from the document: https://docs.splunk.com/Documentation/SplunkCloud/7.2.6/User/ForwardDataToSplunkCloudFromLinux#Step_...

Did your forwarder is listed on forwarder management page as a client?

[csnehal]

No. It was not listed in the forwarder Management page. But I resolved the issue by using input as prefix to server name. This made it visible in Forwarder Management list.
Now I am facing another issue. Handshake is done on machine where forwarder is installed and the splunk server, but the logs are not being forwarded to splunk server
