I have to find out the top 50 Ip addresses for error logs, but they are in a different format than Splunk recognizes. The IP information are listed in the _raw field of the log. I'm not sure how to extract them so I can look at them and chart just the IP addresses in the error logs. I know I can highlight over the IP addresses, but it only shows the logs containing that specific IP address. Is there any way I can tell Splunk exactly what field I want it to extract?
