Sending custom metrics with GraphiteDataWriter

I am considering using the scala metrics package ( to collect additional metrics for my gatling project. I am wondering if there’s any known way to submit these metrics with the gatling graphite data writer either with the metrics package mentioned or replacing where I record data with a gatling metric. I’m using an observer to trigger the function which records these metrics so I’m in a bit of a tricky spot on how to record this information.
