NodesStatsRequest

public NodesStatsRequest(String... nodesIds)

Get stats from nodes based on the nodes ids specified. If none are passed, stats for all nodes will be returned.

Method Details

all

public NodesStatsRequest all()

Sets all the request flags.

clear

public NodesStatsRequest clear()

Clears all the request flags.

indices

public CommonStatsFlags indices()

Get indices. Handles separately from other metrics because it may or may not have submetrics.

Returns:

flags indicating which indices stats to return

indices

public NodesStatsRequest indices(CommonStatsFlags indices)

Set indices. Handles separately from other metrics because it may or may not involve submetrics.

Parameters:

indices - flags indicating which indices stats to return

Returns:

This object, for request chaining.

indices

public NodesStatsRequest indices(boolean indices)

Should indices stats be returned.

requestedMetrics

public Set<String> requestedMetrics()

Get the names of requested metrics, excluding indices, which are handled separately.

addMetric

public NodesStatsRequest addMetric(String metric)

Add metric

addMetrics

public NodesStatsRequest addMetrics(String... metrics)

Add an array of metric names

removeMetric

public NodesStatsRequest removeMetric(String metric)

Remove metric

createTask

public Task createTask(long id,
 String type,
 String action,
 TaskId parentTaskId,
 Map<String,String> headers)

Description copied from interface: TaskAwareRequest
