Hi,

I need to display value (string) of a field depending on the value of this field in previous event.
Something like this :

if previous_event.field = "toto" then display current_event.field else display "anomaly"
I've found something interesting with "transatcion" by I can't achieve to do this.

Any help is welcome.

Thanks in advance.

Regards

autoregress is going to be the simplests solution for you.

i.e.

 somesearch 
 | autoregress myfield as prev_myfield
 | eval display_field=if(prev_myfield=="toto",myfield,"anomoly")

if you need something more advanced than auoregress, streamstats allows you to do "by" clasuses etc.
