Splunk Operational Intelligence Cookbook
In this recipe, you will learn how to add hostnames to IP addresses in the log data by leveraging external lookups. There are many times where a hostname value can be more valuable than an IP address, and it can provide an easier identifier around what clients are connecting to your application.
