Grok Pattern for WSO2 Audit Log file
<p>This is a example from WSO2 Audit log file</p>

<pre><code>[2016-11-22 00:20:30,657]  INFO -  Initiator : wso2.system.user | Action : 
Change Password by User | Target : admin | Data : {  } | Result : Success
</code></pre>

<p>I am trying to write a Grok pattern using frok debugger, but all I am getting is No Matches.</p>

<pre><code>\[%{TIMESTAMP_ISO8601:timestamp}\]%{SPACE}%{LOGLEVEL:level}-%{SPACE}%
{GREEDYDATA:log_message}
</code></pre>
