Mysqlnd replication and load balancing plugin (mysqlnd_ms)
Statistic Description
Number of
trx_autocommit_on autocommit
figure may be used to monitor activity related to the plugin
configuration setting trx_stickiness. If, for example, you want
to know if a certain API call invokes the
trx_autocommit(), which is a requirement for trx_stickiness,
you may call the user API function in question and check if the statistic
has changed. The statistic is modified only by the plugins internal
subclassed

Example 20.299.
mysqlnd_ms_get_stats
<?php
printf("mysqlnd_ms.enable = %d\n", ini_get("mysqlnd_ms.enable"));
printf("mysqlnd_ms.collect_statistics = %d\n", ini_get("mysqlnd_ms.collect_statistics"));
var_dump(mysqlnd_ms_get_stats());

The above example will output:
