Extracting a number a my query not working

[ramkrishs]

Hi i have a log like this  Elapsed time: prediction timer 0.1953 seconds 

and i created a rex like this rex "Elapsed\stime:\sprediction\stimer\s(?<predictionTime>\d+)\sseconds"

but i am unable to find the value at all what am i missing here ? any help would be appreciated

Your regex specifies that your capture group consists of digits only (at least one digit) and then immediately you get a space.

In your event you have a decimal fraction as well.

So you need

\d+(\.\d+)?
