Interface StatsDClient

All Known Implementing Classes:

NonBlockingStatsDClient, NoOpStatsDClient

public interface StatsDClient

Describes a client connection to a StatsD server, which may be used to post metrics in the form of counters, timers, and gauges.

Three key methods are provided for the submission of data-points for the application under scrutiny:

• incrementCounter(java.lang.String, java.lang.String...) - adds one to the value of the specified named counter
• recordGaugeValue(java.lang.String, double, java.lang.String...) - records the latest fixed value for the specified named gauge
• recordExecutionTime(java.lang.String, long, java.lang.String...) - records an execution time in milliseconds for the specified named operation
