Attributes (22)

  • 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
  • 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
  • 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
  • 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
  • current_coord The address of the current coordinator
    • Attribute Value
    Type STRING
    Nillable true
    Expressions Allowed false
    Storage runtime
    Access Type metric
  • discovery_rsp_expiry_time Expiry time of discovery responses in ms
    • Attribute Value
    Type LONG
    Nillable true
    Expressions Allowed false
    Storage runtime
    Access Type metric
  • 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
  • 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
  • is_coord Whether this member is the current coordinator
    • Attribute Value
    Type BOOLEAN
    Nillable true
    Expressions Allowed false
    Storage runtime
    Access Type metric
  • level logger level (see javadocs)
    • Attribute Value
    Type STRING
    Nillable true
    Expressions Allowed false
    Storage runtime
    Access Type metric
  • 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
  • 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
  • num_discovery_requests Total number of discovery requests sent
    • Attribute Value
    Type INT
    Nillable true
    Expressions Allowed false
    Storage runtime
    Access Type metric
  • num_discovery_runs The number of times a discovery process is executed when finding initial members (https://issues.jboss.org/browse/JGRP-2317)
    • Attribute Value
    Type INT
    Nillable true
    Expressions Allowed false
    Storage runtime
    Access Type metric
  • 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
  • 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
  • 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
  • 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
  • stats Determines whether to collect statistics (and expose them via JMX). Default is true
    • Attribute Value
    Type BOOLEAN
    Nillable true
    Expressions Allowed false
    Storage runtime
    Access Type metric
  • transport_supports_multicasting Whether the transport supports multicasting
    • Attribute Value
    Type BOOLEAN
    Nillable true
    Expressions Allowed false
    Storage runtime
    Access Type metric
  • use_disk_cache If a persistent disk cache (PDC) is present, combine the discovery results with the contents of the disk cache before returning the results
