Hi @Ramana246,
your question is just a little vague!
Anyway, you can read the documentation about Getting Data in at https://docs.splunk.com/Documentation/SplunkCloud/latest/Admin/IntroGDI or see some video on YouTube Splunk Channel like https://www.youtube.com/watch?v=gHzUW9oOvKA or https://www.splunk.com/en_us/resources/videos/getting-data-in-to-splunk-enterprise-windows.html or https://www.splunk.com/en_us/resources/videos/getting-data-in-to-splunk-enterprise-linux.html
Ciao.
Giuseppe
