ejabberd route表

• 遍历route表

  mod_muc_room_util:traversal_mnesia(route).   

  运行结果

  [<<"im.cjzhibo.net">>,<<"pubsub.im.cjzhibo.net">>,
  <<"irc.im.cjzhibo.net">>,<<"conference.im.cjzhibo.net">>]

• 读取<<”im.cjzhibo.net”>>键值

  mnesia:dirty_read(route,<<"conference.im.cjzhibo.net">>).

  运行结果

  [{route,<<"conference.im.cjzhibo.net">>,
  <<"im.cjzhibo.net">>,<0.426.0>,undefined}]

• 获取<0.426.0>对应的进程信息

  B = pid(0,426,0).
  erlang:process_info(B).  

  运行结果

  [{registered_name,'ejabberd_mod_muc_im.cjzhibo.net'},
  {current_function,{gen_server,loop,6}},
  {initial_call,{proc_lib,init_p,5}},
  {status,waiting},
  {message_queue_len,0},
  {messages,[]},
  {links,[<0.146.0>,<0.306.0>]},
  {dictionary,[{'$ancestors',[ejabberd_sup,<0.42.0>]},
            {'$initial_call',{mod_muc,init,1}}]},
  {trap_exit,false},
  {error_handler,error_handler},
  {priority,normal},
  {group_leader,<0.41.0>},
  {total_heap_size,121535},
  {heap_size,75113},
  {stack_size,9},
  {reductions,181887},
  {garbage_collection,[{min_bin_vheap_size,46422},
                    {min_heap_size,233},
                    {fullsweep_after,65535},
                    {minor_gcs,55}]},
  {suspending,[]}]

  找到对应的注册进程名为{registered_name,'ejabberd_mod_muc_im.cjzhibo.net'}

• 结束
  至此，找到了ejabberd route信息的一个大概过程
