- Method Detail
  - open
```
void open(MetricConfig config)
```
    Configures this reporter.
    If the reporter was instantiated generically and hence parameter-less, this method is the place where the reporter sets it's basic fields based on configuration values. Otherwise, this method will typically be a no-op since resources can be acquired in the constructor.
    This method is always called first on a newly instantiated reporter.
    
    Parameters:
    
    config - A properties object that contains all parameters set for this reporter.
  - close
```
void close()
```
    Closes this reporter. Should be used to close channels, streams and release resources.

void notifyOfAddedSpan(Span span)
```
