Constructor Detail

StatsdPlugin

public StatsdPlugin(String host,
            int port,
            String appName)
             throws UnknownHostException,
                    SocketException

Create a Statsd plugin with a specified host and port. caller needs to call register on the plugin to register it into the InApplicationMonitor

Parameters:

host - the host of the Statsd server.

port - the port of the Statsd server.

appName - a short application identifier to fulfill IS24 / Graphite naming scheme requirements through statsd

Throws:

UnknownHostException - if there is no such host as specified.

SocketException - if the socket to the host could not be opened.

             throws UnknownHostException,
                    SocketException

Create a Statsd plugin with a specified host and port. caller needs to call register on the plugin to register it into the InApplicationMonitor

Parameters:

host - statsd host name

port - udp port statsd is listening on

appName - a short application identifier to fulfill IS24 / Graphite naming scheme requirements through statsd

sampleRate - a default sample rate to use for all metrics handled

Throws:

UnknownHostException
