    the number of requests recorded by this stat.
  - getRequestsOverflow
```
public int getRequestsOverflow()
```

    the number of requests which exceed the max expected latency
  - getMaxTrackedLatencyMillis
```
public int getMaxTrackedLatencyMillis()
```
    Returns:
    
    the max expected latency for this kind of operation
  - getMin
```
public int getMin()
```
    Returns:
    
    the fastest latency tracked
  - getMax
```
public int getMax()
```
    Returns:
    
    the slowest latency tracked
  - getAvg
```
public float getAvg()
```
    Returns:
    
    the average latency tracked
  - get95thPercent
```
public int get95thPercent()
```
    Returns:
    
    the 95th percentile latency tracked by the histogram
  - get99thPercent
```
public int get99thPercent()
```
    Returns:
    
    the 99th percentile latency tracked by the histogram
  - rollup
```
public void rollup(Latency other)
```
    Add the measurements from "other" and recalculate the min, max, and average values. The 95th and 99th percentile are not recalculated, because the histogram from LatencyStatis not available, and those values can't be generated.
