I have this pattern:  
2017-07-13T00:00:04,621 [WARN][Client-Push:1:3][PfFwdPointSubscriptionService] SEKHKD is disabled  
I am able to match up to [client push1:3]

Using this:  
\A%{TIMESTAMP\_ISO8601:timestamp}\s+[%{LOGLEVEL:loglevel}\s+][(?(?:[A-Za-z0-]_:[0-9]:[0-9]))](?(?:[[^.$]_]))

I need to get rid of the square brackets by PfFwdPointSubscriptionService. Seems simple but I may be missing something.

{  
"timestamp": [  
[  
"2017-07-13T00:00:04,621"  
]  
],  
"loglevel": [  
[  
"WARN"  
]  
],  
"thread": [  
[  
"Client-Push:1:3"  
]  
],  
"bean": [  
[  
**"[PfFwdPointSubscriptionService]"**  
]  
]  
}

For the following log-\>

`2017-07-13T00:00:04,621 [WARN][Client-Push:1:3][PfFwdPointSubscriptionService] SEKHKD is disabled`

The Grok pattern is -\>

`^%{TIMESTAMP_ISO8601:timestamp},%{NUMBER:tz} \[%{LOGLEVEL:loglevel} \]\[%{GREEDYDATA:client_push}\]\[%{GREEDYDATA:Service}\] %{GREEDYDATA:msg}`

Output in [https://grokdebug.herokuapp.com/](https://grokdebug.herokuapp.com/)

```
{
  "timestamp": [
    [
      "2017-07-13T00:00:04"
    ]
  ],
  "tz": [
    [
      "621"
    ]
  ],
  "loglevel": [
    [
      "WARN"
    ]
  ],
  "client_push": [
    [
      "Client-Push:1:3"
    ]
  ],
  "Service": [
    [
      "PfFwdPointSubscriptionService"
    ]
  ],
  "msg": [
    [
      "SEKHKD is disabled"
    ]
  ]
}
