How to create a Gauge metric?

[panduz86]

Hello,

I open this ticket because I don't figure how to create a Gauge metric with this library. In the example provided you show how to do for a Counter

val driverMetricsSystem = UserMetricsSystems
        .getMetricSystem(METRICS_NAMESPACE, builder => {
          builder.registerCounter(COUNTER_NAME)
        })

but the builder object doesn't offer a method "registerGauge", there is a generic "register" method with receives 2 parameters: the name and the metric object.

Could you please provide some documentation about this case?

Thank you
