The following should work:

```auto
"\[%{MONTHDAY:day}-%{MONTH:month}-%{YEAR:year} %{TIME:time}\]"

```

Please direct future question to the #logstash topic.

Thanks a lot @ jakelandis it works . But I need a single variable timestamp which should contain all date and time sothat I can use that in visualization in kibana.

</div>

In that case you will want something like the following :

```auto
  grok {
     match => {
       message => "\[%{DATA:ts}\]"
     }
   }
  date {
    match => ["ts", "dd-MMM-yyyy HH:mm:ss"]
    remove_field => ["ts"]
  } 

```

Please direct future Logstash question to the #logstash topic.
