描述

My service is outputting metrics to Grafana but it's end points are never called. What I'm finding is that the standard deviation value is NaN, output via:

send(util.format('%s.%s', histogram.name, 'stddev'), histogram.stdDev(), timestamp);

in graphite-reporter.js. I suspect this should output zero.
