Additional Information.  The output lists all event subscriptions; for each subscription a header line and a list of categories with their current log levels is printed. The following information is included in the output:

  • Subscription.  The event subscription's internal ID

  • nodeID.  Node ID of the subscribing node

  • ref.  A block reference, consisting of a block ID from storage/ndb/include/kernel/BlockNumbers.h shifted to the left by 4 hexadecimal digits (16 bits) followed by a 4-digit hexadecimal node number. Block id 0x8000 appears to be a placeholder; it is defined as MIN_API_BLOCK_NO, with the node number part being 1 as expected

  • Category.  The cluster log category, as listed in Event Reports Generated in MySQL Cluster (see also the file storage/ndb/include/mgmapi/mgmapi_config_parameters.h).

  • Level.  The event level setting (the range being 0 to 15).
