Hi,
i have a log format with a timestamp like this :
Dez 08, 2016 8:17:29 AM
I use a custom grok pattern for it in logstash.
When i want elasticsearch to map it i get a mapper\_parsing\_exception.
It says invalid format.
How can i fix it?
My template looks like this:
> "timestamp": {
> "index": "not\_analyzed",
> "type": "date",
> "format": "yyyy-MM-dd HH:mm:ss,SSS||yyyy-MM-dd HH:mm:ss||MMM dd, yyyy HH:mm:ss a",
> "doc\_values": true
> }

In the example above you have `Dez` as the month? Is this a typo or are you using a non-english locale?

If you are using a non-english locale you may need to add the `locale`option to the date field mapping to indicate the locale of the dates in your documents.

I'm curious what locale you are using?

For the given example log it is a german locale
Dez for Dezember
