For example, to return the week of the year that an event occurred in, use the %V variable. For example, if you specify minspan=15m that is equivalent to 900 seconds. If the field name that you specify matches a field name that already exists in the search results, the results of the eval expression overwrite the values in The rest command reads a Splunk REST API endpoint and returns the resource data as a search result. Commands are chained together with a pipe “|” character to indicate that the output of one command feeds into the next command on the right. The where command only returns the results that evaluate to TRUE. fields [+|-] <field-list> Required arguments field-list Syntax: <field>, <field>, Description: Comma-delimited list of fields to keep or remove.
