3.3.4. The Ndb_logevent_type Type

Description.  These are the types of log events available in the MGM API, grouped by event category. (See Section 3.3.7, “The ndb_mgm_event_category Type”.)

Enumeration values. 

Category Type Description
NDB_MGM_EVENT_CATEGORY_CONNECTION   (Connection events)
  NDB_LE_Connected The node has connected
  NDB_LE_Disconnected The node was disconnected
  NDB_LE_CommunicationClosed Communication with the node has been closed
  NDB_LE_CommunicationOpened Communication with the node has been started
  NDB_LE_ConnectedApiVersion The API version used by an API node; in the case of a MySQL server (SQL node), this is the same as displayed by SELECT VERSION()
NDB_MGM_EVENT_CATEGORY_CHECKPOINT   (Checkpoint events)
  NDB_LE_GlobalCheckpointStarted A global checkpoint has been started
  NDB_LE_GlobalCheckpointCompleted A global checkpoint has been completed
  NDB_LE_LocalCheckpointStarted The node has begun a local checkpoint
  NDB_LE_LocalCheckpointCompleted The node has completed a local checkpoint
  NDB_LE_LCPStoppedInCalcKeepGci The lcoal checkpoint was aborted, but the last global checkpoint was preserved
  NDB_LE_LCPFragmentCompleted Copying of a table fragment was completed
NDB_MGM_EVENT_CATEGORY_STARTUP   (Startup events)
  NDB_LE_NDBStartStarted The node has begun to start
  NDB_LE_NDBStartCompleted The node has completed the startup process
  NDB_LE_STTORRYRecieved The node received an STTORRY signal, indicating that the reading of configuration data is underway; see Section 6.5.2, “Configuration Read Phase (STTOR Phase -1)”, and Section 6.5.3, “STTOR Phase 0”, for more information
  NDB_LE_StartPhaseCompleted A node start phase has been completed
  NDB_LE_CM_REGCONF The node has received a CM_REGCONF signal; see Section 6.5.4, “STTOR Phase 1”, for more information
  NDB_LE_CM_REGREF The node has received a CM_REGREF signal; see Section 6.5.4, “STTOR Phase 1”, for more information
  NDB_LE_FIND_NEIGHBOURS The node has discovered its neighboring nodes in the cluster
  NDB_LE_NDBStopStarted The node is beginning to shut down
  NDB_LE_NDBStopCompleted  
  NDB_LE_NDBStopForced The node is being forced to shut down (usually indicates a severe problem in the cluster)
  NDB_LE_NDBStopAborted The started to shut down, but was forced to continue running; this happens, for example, when a STOP command was issued in the management client for a node such that the cluster would no longer be able to keep all data available if the node were shut down
  NDB_LE_StartREDOLog Redo logging has been started
  NDB_LE_StartLog Logging has started
  NDB_LE_UNDORecordsExecuted The node has read and executed all records from the redo log
  NDB_LE_StartReport The node is issuing a start report
NDB_MGM_EVENT_CATEGORY_NODE_RESTART   (Restart events)
  NDB_LE_NR_CopyDict The node is copying the data dictionary
  NDB_LE_NR_CopyDistr The node is copying data distribution information
  NDB_LE_NR_CopyFragsStarted The node is copying table fragments
  NDB_LE_NR_CopyFragDone The node has completed copying a table fragment
  NDB_LE_NR_CopyFragsCompleted The node has completed copying all necessary table fragments
NDB_MGM_EVENT_CATEGORY_NODE_RESTART   (Node failure and arbitration)
  NDB_LE_NodeFailCompleted All (remaining) nodes has been notified of the failure of a data node
  NDB_LE_NODE_FAILREP A data node has failed
  NDB_LE_ArbitState This event is used to report on the current state of arbitration in the cluster
  NDB_LE_ArbitResult This event is used to report on the outcome of node arbitration
  NDB_LE_GCP_TakeoverStarted The node is attempting to become the master node (to assume responsibility for GCPs)
  NDB_LE_GCP_TakeoverCompleted The node has become the master (and assumed responsibility for GCPs)
  NDB_LE_LCP_TakeoverStarted The node is attempting to become the master node (to assume responsibility for LCPs)
  NDB_LE_LCP_TakeoverCompleted The node has become the master (and assumed responsibility for LCPs)
NDB_MGM_EVENT_CATEGORY_STATISTIC   (Statistics events)
  NDB_LE_TransReportCounters This indicates a report of transaction activity, which is given approximately once every 10 seconds
  NDB_LE_OperationReportCounters Indicates a report on the number of operations performed by this node (also provided approximately once every 10 seconds)
  NDB_LE_TableCreated A new table has been created
  NDB_LE_UndoLogBlocked Undo logging is blocked because the log buffer is close to overflowing
  NDB_LE_JobStatistic  
  NDB_LE_SendBytesStatistic Indicates a report of the average number of bytes transmitted per send operation by this node
  NDB_LE_ReceiveBytesStatistic Indicates a report of the average number of bytes received per send operation to this node
  NDB_LE_MemoryUsage A DUMP 1000 command has been issued to this node, and it is reporting its memory usage in turn
