Instance Method Details

#increment_count(value = 1) ⇒ Object

increments the call_count by one

def increment_count(value = 1)
  @call_count += value
end

#inspect ⇒ Object

outputs a human-readable version of the MethodTraceStats object

def inspect
  "#<NewRelic::MethodTraceStats #{summary} >"
end

#record_data_point(value, exclusive_time = value) ⇒ Object Also known as: trace_call

record a single data point into the statistical gatherer. The gatherer will aggregate all data points collected over a specified period and upload its data to the NewRelic server

  @call_count += 1
  @total_call_time += value
  @min_call_time = value if value < @min_call_time || @call_count == 1
  @max_call_time = value if value > @max_call_time
  @total_exclusive_time += exclusive_time

  @sum_of_squares += (value * value)
  self
end

#record_multiple_data_points(total_value, count = 1) ⇒ Object

Records multiple data points as one method call - this handles all the aggregation that would be done with multiple record_data_point calls
