22.5.6.3 X Plugin Status Variables

The X Plugin status variables have the following meanings.

• Mysqlx_aborted_clients

  The number of clients that were disconnected because of an input or output error.

• Mysqlx_address

  The network address or addresses for which X Plugin accepts TCP/IP connections. If multiple addresses were specified using the mysqlx_bind_address system variable, Mysqlx_address displays only those addresses for which the bind succeeded. If the bind has failed for every network address specified by mysqlx_bind_address, or if the skip_networking option has been used, the value of Mysqlx_address is UNDEFINED. If X Plugin startup is not yet complete, the value of Mysqlx_address is empty.

• Mysqlx_bytes_received

  The total number of bytes received through the network. If compression is used for the connection, this figure comprises compressed message payloads measured before decompression (Mysqlx_bytes_received_compressed_payload), any items in compressed messages that were not compressed such as X Protocol headers, and any uncompressed messages.

• Mysqlx_bytes_received_compressed_payload

  The number of bytes received as compressed message payloads, measured before decompression.

• Mysqlx_bytes_received_uncompressed_frame

  The number of bytes received as compressed message payloads, measured after decompression.

• Mysqlx_bytes_sent

  The total number of bytes sent through the network. If compression is used for the connection, this figure comprises compressed message payloads measured after compression (Mysqlx_bytes_sent_compressed_payload), any items in compressed messages that were not compressed such as X Protocol headers, and any uncompressed messages.

• Mysqlx_bytes_sent_compressed_payload

  The number of bytes sent as compressed message payloads, measured after compression.

• Mysqlx_bytes_sent_uncompressed_frame

  The number of bytes sent as compressed message payloads, measured before compression.
