NDB Cluster Configuration Files This parameter specifies where to send cluster logging information. There are three options in this regard— CONSOLE ,  SYSLOG , and  FILE —with  FILE  being the default: Not every facility is necessarily supported by every operating system. The default value for the  FILE  parameter is FILE:filename=ndb_ node_id _cluster.log,maxsize=1000000,maxfiles=6 , where node_id  is the ID of the node. It is possible to specify multiple log destinations separated by semicolons as shown here: This parameter is used to define which nodes can act as arbitrators. Only management nodes and SQL nodes can be arbitrators.  ArbitrationRank  can take one of the following values: • 0 : The node is never used as an arbitrator. • ArbitrationRank • FILE  pipes the cluster log output to a regular file on the same machine. The following values can be specified: • filename : The name of the log file. • maxsize : The maximum size (in bytes) to which the file can grow before logging rolls over to a new file. When this occurs, the old log file is renamed by appending  .N  to the file name, where  N  is the next number not yet used with this name. • maxfiles : The maximum number of log files. • CONSOLE  outputs the log to  stdout : • SYSLOG  sends the log to a  syslog  facility, possible values being one of  auth ,  authpriv ,  cron , daemon ,  ftp ,  kern ,  lpr ,  mail ,  news ,  syslog ,  user ,  uucp ,  local0 ,  local1 ,  local2 ,  local3 , local4 ,  local5 ,  local6 , or  local7 . The default log file name used in such cases is  ndb_ nodeid _cluster.log .
