The fastest way to add data to your Splunk Cloud instance or Splunk Enterprise deployment is to use Splunk Web. After you access the Add Data page, choose one of three options for getting data into your Splunk platform deployment with Splunk Web: (1) Upload, (2) Monitor, (3) Forward The Upload option lets you upload a file or archive of files for indexing. When you choose Upload option, Splunk Web opens the upload process page. Monitor. For Splunk Enterprise installations, the Monitor option lets you monitor one or more files, directories, network streams, scripts, Event Logs (on Windows hosts only), performance metrics, or any other type of machine data that the Splunk Enterprise instance has access to.
