Statistic Scope
Description
Notes
command_buffer_too_small (see
below).
bytes_received_real_data_normal
Connection
Number of bytes of payload fetched by
the PHP client from
mysqlnd
using the
text protocol.
This is the size of the actual data
contained in result sets that do not
originate from prepared statements and
which have been fetched by the PHP
client. Note that although a full result
set may have been pulled from MySQL
by
mysqlnd
, this statistic only counts
actual data pulled from
mysqlnd
by
the PHP client. An example of a code
sequence that will increase the value is
as follows:
$mysqli = new mysqli();
$res = $mysqli->query("SELECT 'abc'");
$res->fetch_assoc();
$res->close();
Every fetch operation will increase the
value.
The statistic will not be increased if the
result set is only buffered on the client,
but not fetched, such as in the following
example:
$mysqli = new mysqli();
$res = $mysqli->query("SELECT 'abc'");
$res->close();
This statistic is available as of PHP
version 5.3.4.
bytes_received_real_data_ps
Connection
Number of bytes of the payload fetched
by the PHP client from
mysqlnd
using
the prepared statement protocol.
This is the size of the actual data
contained in result sets that originate
from prepared statements and which
has been fetched by the PHP client.
The value will not be increased if the
result set is not subsequently read by
the PHP client. Note that although a
full result set may have been pulled
from MySQL by
mysqlnd
, this statistic
only counts actual data pulled from
mysqlnd
by the PHP client. See also
bytes_received_real_data_normal
.
This statistic is available as of PHP
version 5.3.4.
Result Set
Table 20.60. Returned mysqlnd statistics: Result Set
Statistic Scope
Description
Notes
result_set_queries
Connection
Number of queries that have generated
a result set. Examples of queries that
generate a result set:
SELECT
,
SHOW
.
The statistic will not be incremented if
You may use it as an indirect measure
for the number of queries PHP has sent
to MySQL, for example, to identify a
client that causes a high database load.
