Gets the value of the metric with the given name in the current trace. If a metric with the given name doesn't exist, it is NOT created and a 0 is returned. This method is atomic.

actual fun getLongMetric(metricName: String): Long

incrementMetric

actual fun incrementMetric(metricName: String, incrementBy: Long)

expect fun incrementMetric(metricName: String, incrementBy: Long)

Atomically increments the metric with the given name in this trace by the incrementBy value. If the metric does not exist, a new one will be created. If the trace has not been started or has already been stopped, returns immediately without taking action.

actual fun incrementMetric(metricName: String, incrementBy: Long)

putAttribute

fun putAttribute(attribute: String, value: String)

putMetric

actual fun putMetric(metricName: String, value: Long)

expect fun putMetric(metricName: String, value: Long)

Sets the value of the metric with the given name in this trace to the value provided. If a metric with the given name doesn't exist, a new one will be created. If the trace has not been started or has already been stopped, returns immediately without taking action. This method is atomic.
