Field Details

SCRIPT_CLUSTER_SELECTOR_PRECEDENCE

public static final int SCRIPT_CLUSTER_SELECTOR_PRECEDENCE

The relative order of the ScriptClusterSelectorImpl if one is enabled relative to other ClusterSelector instances that may be in the context. This allows users to fit 50 more selectors between the script selector and the default RandomClusterSelectorImpl. If the user wants to place a selector implementation before the script one they only need to subtract from this value.

Method Details

scriptClusterSelector

@Bean
@Order(2147483597)
@ConditionalOnBean(ClusterSelectorManagedScript.class)
public ScriptClusterSelectorImpl scriptClusterSelector(ClusterSelectorManagedScript clusterSelectorManagedScript,
 io.micrometer.core.instrument.MeterRegistry registry)

Produce the ScriptClusterSelectorImpl instance to use for this Genie node if it was configured by the user. This bean is only created if the script is configured.

Parameters:

clusterSelectorManagedScript - the cluster selector script

registry - the metrics registry

Returns:

a ScriptClusterSelectorImpl

randomizedClusterSelector

@Bean
@Order
public RandomClusterSelectorImpl randomizedClusterSelector()

The default cluster selector if all others fail.

Defaults to Ordered.LOWEST_PRECEDENCE.

Returns:

A RandomClusterSelectorImpl instance

commandSelector

@Bean
@ConditionalOnMissingBean(CommandSelector.class)
public CommandSelector commandSelector(Optional<CommandSelectorManagedScript> commandSelectorManagedScriptOptional,
 io.micrometer.core.instrument.MeterRegistry registry)

Provide a default CommandSelector implementation if no other has been defined in the context already.

Parameters:

commandSelectorManagedScriptOptional - An Optional wrapping a CommandSelectorManagedScript instance if one is present in the context else Optional.empty()

registry - The MeterRegistry instance to use

Returns:

A ScriptCommandSelectorImpl if a CommandSelectorManagedScript instance as present else a RandomCommandSelectorImpl instance

agentLauncherSelector

@Bean
@ConditionalOnMissingBean(AgentLauncherSelector.class)
public AgentLauncherSelector agentLauncherSelector(Optional<AgentLauncherSelectorManagedScript> agentLauncherSelectorManagedScript,
 @NotEmpty
 @NotEmpty Collection<AgentLauncher> agentLaunchers,
 io.micrometer.core.instrument.MeterRegistry registry)

Provide a default AgentLauncherSelector implementation if no other has been defined in the context.

Parameters:

agentLauncherSelectorManagedScript - An Optional AgentLauncherSelectorManagedScript instance if one is present in the context

agentLaunchers - The available agent launchers

registry - The MeterRegistry instance to use

Returns:

A ScriptAgentLauncherSelectorImpl if a AgentLauncherSelectorManagedScript instance is present, else a RandomAgentLauncherSelectorImpl instance
