I am getting a little frustrated with this search... I have a field that just does not want to release the NULL value.
| eval src_ip=if(isnull(src_ip),"No IP",src_ip)
| search Username="*-a"
| convert ctime(_time) as datetime
| replace "-" WITH "" IN Username
| where isnotnull (Username)
| stats values(datetime) by src_ip, Username, ComputerName
| rename src_ip as "Client Address" Username as User_ID ComputerName as "Reporting Server" count as "Number of Successful Login Attempts" percent as "Percent"
Client Address User_ID Reporting Server values(datetime)
xx.x.xxx.x xxx-xxx.ctg.com 12/27/2016 09:10:00
xx.x.xxx.x xxxxxx-a xxx-xxx.ctg.com 12/27/2016 09:10:00
I have tried multiple variations to get rid of the null value such as the where isnotnull, search Username!=,.. and others.
Does anyone else have a suggestion for me to try?
I ran into the same problem.
| where isnotnull(Username) AND Username!=""
Try this (just replace your where command with this, rest all same)
| where isnotnull(Username) AND trim(Username)!=""
No luck, I get zero results found by adding trim.
