Hi to all and sorry for my English. I'll try to be detailed to explain the problem.
I can no longer see some hosts on the Home of Splunk after using the command "host = nameofhost | delete" and have reinstalled Splunk on hosts (changing the name of the host in inputs.conf).
There are no errors in the logs and I have tried several times to reinstall but I can not add them again. If I do the installation on other hosts never added in Splunk server (where I never run the command "host = nameofhost | delete"), they are immediately added to the Home of Splunk.
How do I add them again?
