Which are the fields you want to save?

Actually the Input you put there does not match the pattern.

Try something like this:

`%{WORD:word1}:%{NUMBER:n1}\|%{WORD:word2}\|%{WORD:word3}\|%{GREEDYDATA:n2}\|%{NUMBER:response_code}\|%{GREEDYDATA:string}`

Hope it helps 🙂

Have you tried to escape the `|` char?

Try the pattern of my previous publication:

```auto
%{WORD:word1}:%{NUMBER:n1}\|%{WORD:word2}\|%{WORD:word3}\|%{GREEDYDATA:n2}\|%{NUMBER:response_code}\|%{GREEDYDATA:string}

```

If you only need two fields, just discard the rest of them

Thank you @79g i followed your code and learn it  
My new grok pattern is

```auto
^CEES.*\|%{INT:response_code}\|%{GREEDYDATA:log_message

```

Happy to help 🙂 Just mark my reply as solution for making easier for others to find.

You can not put the character `|` inside JSON without escaping. Some special characters could be interpreted and cause failures. To avoid this is necessary to add a `\` before. You can search about `json escaping`

By default, | is used for alternation, so that you might match either AM or PM in a timestamp using `(AM|PM)`. If you have a literal | in the message then you need to escape it with a backslash for the regexp to match it.
