I have a log file collected using a FileBeat that looks like:

`10:21:38.014 DEBUG org.apache.zookeeper.ClientCnxn [main-SendThread(zookeeper3.piranhakik.com:2181)] - Got ping response for sessionid: 0x355bca8e39f0c51 after 0ms`

I have GROK filter which is as follows:

> ```
> filter {
> if [type] == "tigase-kik" {
> grok {
> match => { "message" => "%{TIGASEACCESS}" }
> }
> }
> }
> #pattern file
> KIK_TIMESTAMP HH:mm:ss.SSS
> REMAINING_LOG_MESSAGE (.*)
> TIGASEACCESS %{KIK_TIMESTAMP:timestamp} %{LOGLEVEL:level} %{REMAINING_LOG_MESSAGE}
> 
> ```

But am getting the following error

> {  
> "message" =\> "11:48:08.472 DEBUG c.k.c.p.c.XXXXXX [pool-40-thread-1] - XXXXX XXX XXX XXXX",  
> "@version" =\> "1",  
> "@timestamp" =\> "2016-08-05T15:48:08.859Z",

> "name" =\> "[XXXX.XXX.com](http://XXXX.XXX.com)"

> "source" =\> "/opt/kik/XXXX/logs/XXXX-XXXX.log",  
> "host" =\> "[XXXX.XXXXX.com](http://XXXX.XXXXX.com)",  
> "tags" =\> [  
> [0] "beats\_input\_codec\_plain\_applied",  
> [1] "\_grokparsefailure"  
> ]  
> }

How do I go about testing the grok definition and any idea whats going wrong for me?

Have you tried the Grok Debugger? [https://grokdebug.herokuapp.com/](https://grokdebug.herokuapp.com/)  
And here are some default grok patterns, it may be helpful [https://github.com/elastic/logstash/blob/v1.4.2/patterns/grok-patterns](https://github.com/elastic/logstash/blob/v1.4.2/patterns/grok-patterns)
