Use the rex statement, for example this regex

| makeresults
| eval field = " service error rate 50x 8.976851851851853"
| rex field=field "service error rate\s+\w+\s+(?<value>\d+\.\d)"

 (this is an example you can run in a search window).

Change your regex statement to match what you expect in the data
