collect

public void collect(JmxCollectorConfig config,
                    JmxSampleProcessor sampleProcessor)
             throws JmxServerConnectionException

Description copied from interface: JmxCollector

Implements the logic for the jmx data collection.

Therefore it should somehow: 1. establish the connection to the configured ip address. 2. collect the configured data. 3. inform the JmxSampleProcessor about the collected data.

The JmxSampleProcessor is a callback for each sample collected. Therefore each sample can be transformed to another data structure (e.g. collectd).

Specified by:

collect in interface JmxCollector

Parameters:

config - The configuration to use for the collection.

sampleProcessor - The callback to process each sample.

Throws:

JmxServerConnectionException - If the connection to the jmx server could not be established (whatever the reason).

setJmxConfigDao

public void setJmxConfigDao(JmxConfigDao jmxConfigDao)

Method for setting the config dao to use. Required for the tests to work properly.

Parameters:

jmxConfigDao - the dao instance
