For example, the first empty value found in field1, insert unknown1. The second empty value found in field1, insert unknown2, etc...</P> <P>Any suggestions?</P> Thu, 06 Feb 2020 18:12:59 GMT https://community.splunk.com/t5/Splunk-Search/Use-fillnull-to-fill-in-different-values-within-same-field/m-p/463212#M130582 rfranco83 2020-02-06T18:12:59Z https://community.splunk.com/t5/Splunk-Search/Use-fillnull-to-fill-in-different-values-within-same-field/m-p/463213#M130583 <P>Assuming all the events have a null, or you just need them to be unique (not sequential) try this:</P> <PRE><CODE>|streamstats count as ct|eval yourNullField=if(isnull(yourNullField),"Unknown "+ct,yourNullField) </CODE></PRE> Thu, 06 Feb 2020 19:45:49 GMT https://community.splunk.com/t5/Splunk-Search/Use-fillnull-to-fill-in-different-values-within-same-field/m-p/463213#M130583 nickhills 2020-02-06T19:45:49Z https://community.splunk.com/t5/Splunk-Search/Use-fillnull-to-fill-in-different-values-within-same-field/m-p/463214#M130584 <P>Thank you for your reply.<BR /> What that did was fill in the empty values all the same with "Unknown" and "# of events" for a particular field.
