Create alert which contains data from log previous to trigger

[huu_huynh]

Hello,

I'm trying to create an alert which will be triggered by a field in a log file and extract the data earlier in the log to assist with troubleshooting.

Extract of log with error below. I have highlighted the error I need to identify and the data previous to the error which I need to send.

I've created a field for Invoice number which I want to be the trigger for the alert and then return the rows I need but having trouble how to do this.
