25.6.17.65 The ndbinfo transporter_details Table

This table contains information about individual NDB transporters, rather than aggregate information as shown by the transporters table.

The transporter_details table contains the following columns:

• node_id

  This data node's unique node ID in the cluster

• block_instance

• trp_id

  The transporter ID

• remote_node_id

  The remote data node's node ID

• status

  Status of the connection

• remote_address

  Name or IP address of the remote host

• bytes_sent

  Number of bytes sent using this connection

• bytes_received

  Number of bytes received using this connection

• connect_count

  Number of times connection established on this transporter

• overloaded

  1 if this transporter is currently overloaded, otherwise 0

• overload_count

  Number of times this transporter has entered overload state since connecting

• slowdown

  1 if this transporter is in slowdown state, otherwise 0

• slowdown_count

  Number of times this transporter has entered slowdown state since connecting

• encrypted

  If this transporter is connected using TLS, this column is 1, otherwise it is 0.

• sendbuffer_used_bytes

  The amount, in bytes, of signal data currently awaiting send by this transporter.

• sendbuffer_max_used_bytes

  The maximum amount, in bytes, of signal data awaiting send at any one time by this transporter.

• sendbuffer_alloc_bytes

  Amount of send buffer, in bytes, currently allocated for signal data storage for this transporter.

• sendbuffer_max_alloc_bytes

  Maxmimum amount of send buffer, in bytes, allocated for signal data storage at any one time for this transporter.

• type

  The connection type used by this transporter (TCP or SHM).

The transporter_details table displays a row showing the status of each transporter in the cluster. See the Notes for the transporters table for more information about each of the columns in this table.

The type column was added in NDB 9.0.0.
