Introduction

In a typical MySQL setup, monitoring and tracking various metrics is crucial for ensuring the health and performance of the database server. One such metric is mysql_global_status_mysqlx_ssl_server_not_after, which is used to track the expiration date of the SSL certificate used by the MySQL server. However, in some cases, this metric may not be visible on certain MySQL installations, even when SSL is enabled and configured correctly. In this article, we will explore the possible reasons behind this discrepancy and provide guidance on how to troubleshoot and resolve the issue.

Understanding the Metrics

Before we dive into the troubleshooting process, let's first understand what the mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics represent. These metrics are used to track the expiration date and start date of the SSL certificate used by the MySQL server. The mysql_global_status_mysqlx_ssl_server_not_after metric displays the date when the SSL certificate will expire, while the mysql_global_status_mysqlx_ssl_server_not_before metric displays the date when the SSL certificate was issued.

Situations Where the Metrics May Not Appear

There are several situations where the mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics may not appear on a MySQL server:

SSL is not enabled: If SSL is not enabled on the MySQL server, these metrics will not be available.
Incorrect SSL configuration: If the SSL configuration is incorrect or incomplete, these metrics may not appear.
Missing SSL certificate: If the SSL certificate is missing or not properly installed, these metrics will not be available.
MySQL version: The mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics may not be available on older versions of MySQL.
mysqld_exporter version: The version of the mysqld_exporter may also affect the availability of these metrics.

Troubleshooting the Issue

To troubleshoot the issue of missing mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics, follow these steps:

Verify SSL configuration: Ensure that SSL is enabled and configured correctly on the MySQL server.
Check SSL certificate: Verify that the SSL certificate is installed and properly configured on the MySQL server.
Check MySQL version: Ensure that the MySQL version is compatible with the mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics.
Check mysqld_exporter version: Ensure that the version of the mysqld_exporter is compatible with the mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics.
Check for errors: Check the MySQL error log for any errors related to SSL or the mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics.

Resolving the Issue

To resolve the issue of missing mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics, follow these steps:

Update MySQL version: Update the MySQL version to a compatible version that supports the mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics.
Update mysqld_exporter version: Update the version of the mysqld_exporter to a compatible version that supports the mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics.
Reconfigure SSL: Reconfigure the SSL settings on the MySQL server to ensure that the mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics are available.
Restart MySQL server: Restart the MySQL server to ensure that the changes take effect.

Conclusion

In conclusion, the mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics are used to track the expiration date and start date of the SSL certificate used by the MySQL server. However, in some cases, these metrics may not be visible on certain MySQL installations, even when SSL is enabled and configured correctly. By following the troubleshooting steps outlined in this article, you can identify and resolve the issue of missing mysql_global_status_mysqlx_ssl_server_not_after and mysql_global_status_mysqlx_ssl_server_not_before metrics.
