Hi All,

Here is a snapshot of my logstash config file:

 ![Capture](https://us1.discourse-cdn.com/elastic/original/3X/9/c/9c05c4a2b44b70077be1b5f5a9947f2ed0f06876.PNG)

The Date filter is able to match the field logtime to the pattern yyyy-MM-dd hh:mm:ss but while creating index I can only see the field @timestamp in the dropdown; the logtime field comes as string only.

All help is greatly appreciated  
Arun

That appears to be working as expected. The date filter does not modify its source field, it writes to the "target" field. So logtime will be a string, and @timestamp will be a datetime.

Also, you probably want to `remove_field => ["logtime"]` in your date filter, since `timestamp` isn't a field that exists in your grok pattern.

@Badger, @tgaudin thanks a lot! It worked 🙂
