I recently started a new job and used Splunk at my old one. I know the power of Splunk and know it will be useful for my new job. We have downloaded the free version to see how much data we are processing to determine which version of Splunk we will need, I just am having a hard time getting it setup. Is there any current documentation or videos on how to add your network nodes to Splunk to gather data? A lot of what I am seeing is 5+ years outdated.
what do you mean network nodes?
if you want to index server data, just install a universal forwarder.
if you want to index network appliances data (e.g firewall, LB, etc) depending on the vendor/tech most likely you'll be using syslog to send data to Splunk.
if you want to get data from DBs, just install Splunk DB Connect.
if you want to get wire data, just use Splunk Stream.
------------ Hope I was able to help you. If so, an upvote would be appreciated.
