com.h3c.sdn.metric.HistogramDescriptor.HistogramDescriptorBuilder

Enclosing class:

HistogramDescriptor

public static class HistogramDescriptor.HistogramDescriptorBuilder
extends MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Histogram descriptor builder object, which requires that only arguments that are mandatory for the construction of a HistogramDescriptor be specified during its own construction. Values may also be specified for the optional arguments needed for a HistogramDescriptor, but these values are defaulted in the event that no value is specified for them.

Constructor Detail

HistogramDescriptor.HistogramDescriptorBuilder

public HistogramDescriptor.HistogramDescriptorBuilder(String name)

Creates a new HistogramDescriptor.HistogramDescriptorBuilder using only the arguments that are required to build a valid HistogramDescriptor. If no other fields are set via other methods before building, the resulting HistogramDescriptor will specify a TimeStampedHistogram associated with no specific application, no primary or secondary tags, no description, and that the resulting TimeStampedHistogram should be persisted using the default summarization interval and should not be visible via JMX.

Parameters:

name - a name for the TimeStampedHistogram (e.g. "txPackets")

Method Detail

build

public HistogramDescriptor build()

Build a HistogramDescriptor instance.

Specified by:

build in class MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Returns:

the resulting HistogramDescriptor

appId

public HistogramDescriptor.HistogramDescriptorBuilder appId(String toSet)

Description copied from class: MetricDescriptor.MetricDescriptorBuilder

Sets the application ID to apply to the MetricDescriptor that will be built.

Overrides:

appId in class MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Parameters:

toSet - application ID

Returns:

self

description

public HistogramDescriptor.HistogramDescriptorBuilder description(String toSet)

Description copied from class: MetricDescriptor.MetricDescriptorBuilder

Sets the description to apply to the MetricDescriptor that will be built.

Overrides:

description in class MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Parameters:

toSet - description

Returns:

self

name

public HistogramDescriptor.HistogramDescriptorBuilder name(String toSet)

Description copied from class: MetricDescriptor.MetricDescriptorBuilder

Sets the name to apply to the MetricDescriptor that will be built. Many metrics may have the same name (e.g. "txPackets") but can be distinguished from one another via the primary and secondary tags specified.

Overrides:

name in class MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Parameters:

toSet - name

Returns:

self

persist

public HistogramDescriptor.HistogramDescriptorBuilder persist(boolean toSet)

Description copied from class: MetricDescriptor.MetricDescriptorBuilder

Sets the flag that indicates whether the MetricDescriptor that will be built is to be persisted. true indicates that the value should be persisted, false that it shouldn't.

Overrides:

persist in class MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Parameters:

toSet - persistence flag

Returns:

self

primaryTag

public HistogramDescriptor.HistogramDescriptorBuilder primaryTag(String toSet)

Description copied from class: MetricDescriptor.MetricDescriptorBuilder

Sets the primary tag (e.g. "router-1.2.3.4") to apply to the MetricDescriptor that will be built. The tag can be anything that is a useful identifier to group metrics by.

Overrides:

primaryTag in class MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Parameters:

toSet - primary tag

Returns:

self

publishToJmx

public HistogramDescriptor.HistogramDescriptorBuilder publishToJmx(boolean toSet)

Description copied from class: MetricDescriptor.MetricDescriptorBuilder

Sets the flag that indicates whether the MetricDescriptor that will be built should be made visible via JMX. true indicates that the value should be visible, false that it shouldn't.

Overrides:

publishToJmx in class MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Parameters:

toSet - JMX flag

Returns:

self

secondaryTag

public HistogramDescriptor.HistogramDescriptorBuilder secondaryTag(String toSet)

Description copied from class: MetricDescriptor.MetricDescriptorBuilder

Sets the secondary tag (e.g. "port1") to apply to the MetricDescriptor that will be built. The tag can be anything that is a useful identifier to group metrics by, but should make sense in the context of the specified primary tag.

Overrides:

secondaryTag in class MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Parameters:

toSet - secondary tag

Returns:

self

summaryMinutes

public HistogramDescriptor.HistogramDescriptorBuilder summaryMinutes(MetricDescriptor.SummaryIntervalMinutes toSet)

Description copied from class: MetricDescriptor.MetricDescriptorBuilder

Sets the number of minutes that should elapse between the persistence of summarized values to apply to the MetricDescriptor that will be built.

Overrides:

summaryMinutes in class MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Parameters:

toSet - summarization interval (in minutes)

Returns:

self

type

public HistogramDescriptor.HistogramDescriptorBuilder type(MetricDescriptor.Type toSet)

Description copied from class: MetricDescriptor.MetricDescriptorBuilder

Sets the metric type to apply to the MetricDescriptor that will be built.

Overrides:

type in class MetricDescriptor.MetricDescriptorBuilder<HistogramDescriptor>

Parameters:

toSet - metric type

Returns:

self
