Runtime only resource This resource is runtime only and doesn't have any persistent configuration.

Attributes (24)

after_creation_hook Fully qualified name of a class implementing ProtocolHook, will be called after creation of the protocol (before init())

Attribute	Value
Type	STRING
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

async_discovery If true then the discovery is done on a separate timer thread. Should be set to true when discovery is blocking and/or takes more than a few milliseconds

Attribute	Value
Type	BOOLEAN
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

async_discovery_use_separate_thread_per_request If enabled, use a separate thread for every discovery request. Can be used with or without async_discovery

Attribute	Value
Type	BOOLEAN
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

break_on_coord_rsp Return from the discovery phase as soon as we have 1 coordinator response

Attribute	Value
Type	BOOLEAN
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

current_coord The address of the current coordinator

Attribute	Value
Type	STRING

discovery_rsp_expiry_time Expiry time of discovery responses in ms

Attribute	Value
Type	LONG

Access Type	metric
Stability	default

ergonomics Enables ergonomics: dynamically find the best values for properties at runtime

Attribute	Value
Type	BOOLEAN
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

id Give the protocol a different ID if needed so we can have multiple instances of it in the same stack

Attribute	Value
Type	INT
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

is_coord Whether this member is the current coordinator

Attribute	Value
Type	BOOLEAN

Stability	default

level logger level (see javadocs)

Attribute	Value
Type	STRING
Nillable	true

Storage	runtime
Access Type	metric
Stability	default

local_addr The local address of this member

Attribute	Value
Type	STRING
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

max_members_in_discovery_request Max size of the member list shipped with a discovery request. If we have more, the mbrs field in the discovery request header is nulled and members return the entire membership, not individual members

Attribute	Value
Type	INT
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

max_rank_to_reply The max rank of this member to respond to discovery requests, e.g. if max_rank_to_reply=2 in {A,B,C,D,E}, only A (rank 1) and B (rank 2) will reply. A value <= 0 means everybody will reply. This attribute is ignored if TP.use_ip_addrs is false.

Attribute	Value
Type	INT
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

num_discovery_requests Total number of discovery requests sent

Attribute	Value
Type	INT
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

num_discovery_runs The number of times a discovery process is executed when finding initial members (https://issues.redhat.com/browse/JGRP-2317)

Attribute	Value
Type	INT
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

policies The list of policies

Attribute	Value
Type	STRING
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

return_entire_cache Whether or not to return the entire logical-physical address cache mappings on a discovery request, or not.

Attribute	Value
Type	BOOLEAN
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

send_cache_on_join When a new node joins, and we have a static discovery protocol (TCPPING), then send the contents of the discovery cache to new and existing members if true (and we're the coord). Addresses JGRP-1903

Attribute	Value
Type	BOOLEAN
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

sends_can_block True if sending a message can block at the transport level

Attribute	Value
Type	BOOLEAN
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

stagger_timeout If greater than 0, we'll wait a random number of milliseconds in range [0..stagger_timeout] before sending a discovery response. This prevents traffic spikes in large clusters when everyone sends their discovery response at the same time

Attribute	Value
Type	LONG
Nillable	true
Expressions Allowed	false
Storage	runtime
Access Type	metric
Stability	default

stats Determines whether to collect statistics (and expose them via JMX). Default is true

Attribute	Value
