MySQL 8.4 Reference Manual Including MySQL NDB Cluster 8.4
The X Plugin status variables have the following meanings.
The number of clients that were disconnected because of an input or output error.
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.
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.
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
