NodeInfo

public NodeInfo(Version version, Build build, DiscoveryNode node, @Nullable Settings settings, @Nullable OsInfo os, @Nullable ProcessInfo process, @Nullable JvmInfo jvm, @Nullable ThreadPoolInfo threadPool, @Nullable TransportInfo transport, @Nullable HttpInfo http, @Nullable PluginsAndModules plugins, @Nullable IngestInfo ingest, @Nullable ByteSizeValue totalIndexingBuffer)

Method Details

getHostname

@Nullable public java.lang.String getHostname()

System's hostname. null in case of UnknownHostException

getVersion

public Version getVersion()

The current ES version

getBuild

public Build getBuild()

The build version of the node.

getSettings

@Nullable public Settings getSettings()

The settings of the node.

getInfo

public <T extends ReportingService.Info> T getInfo(java.lang.Class<T> clazz)

Get a particular info object, e.g. JvmInfo or OsInfo. This generic method handles all casting in order to spare client classes the work of explicit casts. This NodeInfo class guarantees type safety for these stored info blocks.

Type Parameters:

T - Specific subtype of ReportingService.Info to retrieve.

Parameters:

clazz - Class for retrieval.

Returns:

An object of type T.

getTotalIndexingBuffer

@Nullable public ByteSizeValue getTotalIndexingBuffer()

writeTo

public void writeTo(StreamOutput out) throws java.io.IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Overrides:

writeTo in class BaseNodeResponse

Throws:

java.io.IOException
