I am having a grok issue. I have a log like below

`Login Success [user: jsaver] [Source: 10.110.20.58]`

How can I parse the this log with grok filter ?

Here is an example to show how it works.

Sample Data - `Login Success [user: jsaver] [Source: 10.110.20.58]`

Pattern - `%{DATA:action} %{DATA:outcome} \[user: %{USERNAME:user}\] \[Source: %{IPV4:source}\]`

Result

```auto
{
  "action": "Login",
  "source": "10.110.20.58",
  "user": "jsaver",
  "outcome": "Success"
}

```

Thanks for the replay.

Is it possible to parse action and outcome together?

like ` "action": "Login Success"`
