option_tracker_usage:*

For each feature available in the MySQL server, a status variable showing the feature's usage is exposed. The name of each variable follows the pattern option_tracker_usage:feature_name, where feature_name is the name of the feature as shown in the OPTION_NAME column of the mysql_option.option_usage table, or in the OPTION_NAME column of the Performance Schema mysql_option. You can obtain all such variables using either of the queries shown here, and their values from the latter query:

mysql> SHOW STATUS LIKE 'option_tracker_usage%';
+------------------------------------------------+-------+
| Variable_name                                  | Value |
+------------------------------------------------+-------+
| option_tracker_usage:Binary Log                | 161   |
| option_tracker_usage:Enterprise Data Masking   | 0     |
| option_tracker_usage:JavaScript Library        | 1     |
| option_tracker_usage:JavaScript Stored Program | 1     |
| option_tracker_usage:Replication Replica       | 0     |
| option_tracker_usage:Vector                    | 0     |

The output just shown is dependent on the features enabled on the system, and thus may not match the output shown on your system precisely. The values of these status variables are updated only if the Option Tracker component, available with MySQL Enterprise Edition, is installed in the system. The status variables themselves are installed by installing the corresponding features, whether the Option Tracker is present, or not.

Each feature obtains the initial value of the status variable at initialization time from the Option Tracker component (if installed) and stores it in the status variable. The Option Tracker persists all such status variables once per hour.

If the Option Tracker component is loaded after the component or plugin implementing the feature, any existing value for the status variable is reset with the persistent value provided by the Option Tracker, with any increments to it before that time being lost.

These status variables were added in MySQL 9.2.1. For more information, see Section 7.5.8.2, “Option Tracker Supported Components”.
