Zabbix Server/Proxy/Agent2 version 7.0.12
When trying to monitor (Percona) MySQL 8.4 replication using the built-in MySQL plugin and the "MySQL by Zabbix Agent 2" template we get an error:
2025/05/16 09:50:45.369228 [Mysql] Cannot fetch data: Error 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SLAVE STATUS' at line 1.
This makes sense as the 'SHOW SLAVE STATUS' command has been deprecated in MySQL 8.0.22 and has been removed in 8.4.
The correct syntax to use on recent MySQL instances is
SHOW REPLICA STATUS;
The output is largely still the same, apart from the fact that the word 'slave' has been replaced by 'replica' everywhere.
Example output on MySQL 8.4.4:

Are there plans to fully support MySQL 8.4? It's the most recent LTS version and has been out since 2024-04-30. As monitoring replication status is
