Start a telemetry span. Additionally, the returned TelemetrySpan object must be made current so that it gets recorded by the telemetry tracer. A TelemetrySpan object must be closed in a finally block after being made current, e.g.: 

TelemetrySpan span = telemetryHandler.startSpan(TelemetrySpanName.PING);
try (TelemetryScope scope = span.makeCurrent()) {
    // your code goes here
} finally {
    span.end();
}
Parameters
spanName:TelemetrySpanName

the span name that identifies this telemetry span

args:Object[]

arguments used for interpolating the specified span name via String#format(String, Object...)

Returns:TelemetrySpan

the newly-created span object
