The management server maintains a list of scalaris nodes and checks their availability using a failure_detector. Its main purpose is to give new scalaris nodes a list of nodes already in the system.

Data Types

message()

message() = 
    {fd_notify,
     fd:event(),
     PID :: comm:mypid(),
     Reason :: fd:reason()} |
    {get_list, SourcePid :: comm:mypid()} |
    {get_list_length, SourcePid :: comm:mypid()} |
    {register, Node :: node:node_type()}

state()

state() = gb_trees:tree(comm:mypid(), node:node_type())

Function Index

init/1
node_list/0	trigger a message with all nodes known to the mgmt server.
node_list/1
number_of_nodes/0	trigger a message with the number of nodes known to the mgmt server.
on/2
start_gen_component/5
start_link/2	starts the server; called by the mgmt supervisor.
