Hello ,
So i'm stuck with a problem here: I have some log files with an **unstructured** data.
I parse them using logstash ( **grok filter** ). The problem is **i want to display them in the same order in the log file** (ordered by their own timestamp not the timestamp they were parsed in).
In order to do this **i need to sort them based on the field "Dates"** (field created using grok to extract the date part ).
Sorting them requires that **this "Dates" field be of date type and not string type**.
How can i parse the new log files using Grok filter and have the "Dates" field a date type.
I have read the documentation about the date in json files and how to reindex , yet they don't seem to make it clearer. here is a sample of the log data:
```
Jan 21 14:00:05.590 OPCM35AVCS207 VCS: [0x00000fd8] Sending CS_CALLACCEPTED for CallID 0x2643c6f14f74035d to: VoIP Connection Server: 861
```
