In the previous chapter, you learned how to extract fields from Splunk using delimiters and regular expressions to create macros and field aliases. You also performed a few Search Processing Language commands to improve your SPL skills. In this chapter, you deal with Splunk tags and lookups and create various reports and alerts. Splunk tags are pairs of nomenclature-added values that assign names to a specific field and its value combination. Splunk lookups enhance data by adding a field/value combination from any internal or external data source. Reports are saved searches or a pivot, which represent related statistics and visuals for later reuse. Meanwhile, alerts are triggered when a search result satisfies any condition.

In the previous chapter, you learned how to extract fields from Splunk using delimiters and regular expressions to create macros and field aliases. You also performed a few Search Processing Language commands to improve your SPL skills. In this chapter, you deal with Splunk tags and lookups and create various reports and alerts. Splunk tags are pairs of nomenclature-added values that assign names to a specific field and its value combination. Splunk lookups enhance data by adding a field/value combination from any internal or external data source. Reports are saved searches or a pivot, which represent related statistics and visuals for later reuse. Meanwhile, alerts are triggered when a search result satisfies any condition.
