Splunk Search

Field reference in search (Not in dashboard) (i.e. Token replacement in search)

Hello,

I try with no success since here to do something like :

| makeresults | eval super_important_field="super_important_value"| eval Rule_Tile="Some interesting Rule Title about $super_important_field$" | <<SOMETHING>>

To at the end got a fields containing :

"Some interesting Rule Title about some_super_important_value"

Just like token replacement in dashboard but in search.

This is an admittedly annoying thing about how Enterprise Security works, as it gives you field values in that format with no builtin, convenient method to template them out. The solution I opted for previously was to create a custom search command that would perform the templating, but this will also work for most cases (with the exception being if your field names happen to look like regexes):

| makeresults 
| eval super_important_field="super_important_value" 
| eval Rule_Title="Some interesting Rule Title about $super_important_field$ things"
| foreach * [eval Rule_Title=replace(Rule_Title, "\$<<FIELD>>\$", <<FIELD>>)]

As an aprovement I've done the folowing in order to "not" be confused by regex syntax
| eval rule_title=replace(rule_title,"\$","§")
| rename rule_title as TicketShort | foreach * [
| eval TicketShort=if(match(TicketShort, "§<>§"), replace(TicketShort, "§<>§",<>),TicketShort)
]
