Data normalization with Tags

Tags in Splunk are useful for grouping events with related field values. Unlike Event Types, which are based on specified search commands, Tags are created and mapped to specific field-value combinations. Multiple Tags can be assigned to the same field-value combination.

IP address Tags
10.2.1.33 main, patched, and east
10.2.1.34 main, patched, and west
10.2.1.35 backup and east
