match

public abstract boolean match(Configuration conf)

An abstract function implemented in the inherited classes JMXSimpleAttribute and JMXComplexAttribute

Parameters:

conf - Configuration a Configuration object that will be used to check if the JMX Attribute match this configuration

Returns:

a boolean that tells if the attribute matches the configuration or not

getMetricsCount

public int getMetricsCount()

getMatchingConf

public Configuration getMatchingConf()

setMatchingConf

public void setMatchingConf(Configuration matchingConf)

getBeanName

public ObjectName getBeanName()

getAlias

protected String getAlias(String field)

Get attribute alias. In order, tries to: * Use `alias_match` to generate an alias with a regular expression * Use `alias` directly * Create an generic alias prefixed with user's `metric_prefix` preference or default to `jmx` Argument(s): * (Optional) `field` `Null` for `JMXSimpleAttribute`.

getAlias

protected String getAlias()

Overload `getAlias` method. Note: used for `JMXSimpleAttribute` only, as `field` is null.

getTags

protected String[] getTags()

getExcludedBeanParams

public static List<String> getExcludedBeanParams()

getDomain

protected String getDomain()

getBeanParameters

protected HashMap<String,String> getBeanParameters()
