Metrics.net with elasticsearch and grafana (name [Percentile 99.9%] cannot contain '.')

[emulk]

Hello,
i'm trying to use Metrics.net with elasticsearch , i have found one of the version working of elasticsearch, is elasticsearch 2.2.0, if i use the last version of elasticsearch, it's not possible to have the data from metrics.net.

I'm having issues with the column name containing "." , like "Percentile 99.9%".

Is possible to change metrics.net column name, or how can i avoide this problem ?

i can't even make it work with the last version of influxdb or the last version of elasticsearch.

Thank you
