Hi,

I have log line like this:

> ",session":"kred06@gmail.com"

Grok Pattern:

```
(,"session":"(%{DATA:name}@%{DATA:company})?")?

```

and I want to split the email to values name and company and also save email as whole to session value. I can split it but I dont know how to save it to session value at the same time.

The values I want:

```
name: "kred06"
company: "gmail.com"
session: "kred06@gmail.com" 

```

Can Anybody help?

An easy solution is to just create a new field after your grok and combine the 2 fields together.

```auto
  mutate {
    add_field => {
      "session" => "%{[name]}@%{[company]}"
    }
  }

```

`"session" => "kred06@gmail.com"`

Thanks, but name and company are marked as optional. When they are not there, it will show in kibana `"session" : "%{[name]}@%{[company]}"` How can I repair this?

Add a conditional to only add that field if company and name both exist.

```auto
  if [name] and [company] {
    mutate {
      add_field => {
        "session" => "%{[name]}@%{[company]}"
      }
    }
  }

```

In my mutate I have also `replace => {"[type]" => "index-name"}` That needs to go throught every time. Can I define multiple mutate blocks?

```
  if [name] and [company] {
    mutate {
      add_field => {
        "session" => "%{[name]}@%{[company]}"
      }
    }
  }
mutate {
       replace => {"[type]" => "index-name"}
}
```
