Could someone help me with Regex to extract suitable fields?

I have the below log and I'm using the following regex to extract these fields "date", "process" ,"step", "user", "log level" 

rex "^(?<Date>\d+-\d+-\d+\s+\d+:\d+:\d+)\s+\[[^\]]*\]\s+\[(?<Process>\[[^\]]+\][^\]]+)\]\s+\[(?<Step>[^\]]+)\]\s+\[(?<User>[^\]]+)\]\s+[^\[]+\[(?<Log_level>[^\]]+)


When the log is like the first entry data is extracted without an issue, but once it's like the last three entries nothing is extracted, how can I solve this.

Your log messages don't quite tally with the regex you say works (as @gcusello ) pointed out. If the spaces are supposed to be absent, try this

^(?<Date>\d+-\d+-\d+\s+\d+:\d+:\d+)\s+\[[^\]]*\]\s*\[(?<Process>[^\]]*)\]\s*\[(?<Step>[^\]]*)\]\s*\[(?<User>[^\]]*)\]\s*[^\[]+\s\[(?<Log_level>[^\]]+)

Thanks this works, how can I also extract the words after the error? So i can identify the error that I received

Hi @sphiwee,

please check this regex:

| rex "^(?<timestamp>\d+-\d+-\d+\s+\d+:\d+:\d+)\s+\[[^\]]*\]\s+\[(?<business_process_name>[^\]]*)\]\s+\[(?<business_process_step>[^\]]*)\]\s+\[(?<users>[^\]]*)\]\s+\w+\s+\[(?<error>[^\]]*)\]"

that you can test at https://regex101.com/r/NuLFWU/1

put attention to this point: you have some missing space in the first row.

Ciao.

Giuseppe
