Hello,
I have created a runtime field named "user". My goal is to extract the username (user=Bob) from a 'event.original' mapping which looks like this:
"event.original": [
"Mar 7 10:17:44 Bob gdm-password][1545478]: "pam_unix(gdm-password:auth): authentication failure; logname= uid=0 euid=0 tty=/dev/tty1 ruser= rhost= user=Bob"
The code I entered for 'Set Value' is:
String user=grok('%GREEDYDATA:leading_data)/user=%
{DATA:user}\'').extract(params._source.event.original)?.user;
if (user != null) emit(user);
I used the code I found from another forum on a similar problem and replaced it with what I thought would work. The code didn't error out, but it's not giving the result I need (i.e. user = Bob). The result is just a blank field.
Could someone help on where I went wrong in the script? Thank you.
