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.
