Hi everyone,

I'm trying to setup the config marvel.history.duration to delete automatically the indices created by Marvel.

The documentation says: Sets the retention duration beyond which the indices created by Marvel will be automatically deleted. Defaults to 7 days. Set to -1 to disable automatic deletion of Marvel indices.

So, I tried to put: `marvel.history.duration: 2` on my elasticsearch.yml but today i got the following error in my logs:

> [2016-05-17 00:59:58,402][ERROR][marvel.cleaner] [noeud-test] failed to clean indices  
> ElasticsearchParseException[Failed to parse setting [marvel.history.duration] with value [2] as a time value: unit is missing or unrecognized]

So, what is the format for this settings. Do i need to put `marvel.history.duration: "2d"` ?

Thank you.
