Troubleshoot connectivity issues in Azure Database for MySQL
In this articleAPPLIES TO: Azure Database for MySQL - Single Server Azure Database for MySQL - Flexible ServerThe MySQL Community Edition manages connections using one thread per connection. As a result, each user connection gets a dedicated operating system thread in the mysqld process. There are potential issues associated with this type of connection handling. For example, memory use is relatively high if there's a large number of user connections, even if they're idle connections. In addition, there’s a higher level of internal server contention and context switching overhead when working with thousands of user connections. Diagnosing common connectivity errorsWhenever your instance of Azure Database for MySQL is experiencing connectivity issues, remember that problems can exist in any of the three layers involved: the client device, the network, or your Azure Database for MySQL server. As a result, whenever you’re diagnosing connectivity errors, be sure to consider full details of the:
It’s also important to determine whether the database connectivity issue is affecting a single client device or several client devices. If the errors are affecting only one of several clients, then it’s likely that the problem is with that client. However, if all clients are experiencing the same error, it’s more likely that the problem is on the database server side or with the networking in between. Be sure to consider the potential of workload overload as well, especially if an application opens a surge of connections in a very short amount of time. You can use metrics such as “Total Connections”, “Active Connections”, and “Aborted Connections” to investigate this. When you establish connectivity from a client device or application, the first important call in mysql is to getaddrinfo, which performs the DNS translation from the endpoint provided to an IP address. If getting the address fails, MySQL shows an error message such as "ERROR 2005 (HY000): Unknown MySQL server host 'mysql-example.mysql.database.azure.com' (11)" and the number in the end (11, 110, etc.). Client-side error 2005 codesQuick reference notes for some client-side error 2005 codes appear in the following table.
The second call in mysql is with socket connectivity and when looking at an error message like "ERROR 2003 (HY000): Can't connect to MySQL server on 'mysql-example.mysql.database.azure.com' (111)", the number in the end (99, 110, 111, 113, etc.). Client-side error 2003 codesQuick reference notes for some client-side error 2003 codes appear in the following table.
Other error codesQuick reference notes for some other error codes related to issues that occur after the network connection with the database server is successfully established appear in the following table.
