完整报错信息如下:
There is no data for the selected Mysql instance, time range or search query.
QAN api error: "qh.Profile: No query classes for selected instance and time range. Please check whether your mysql settings match the recommended.".
Check the /var/log/qan-api.log file in Docker container for more infORMation.
解决方法:
PMM使用slow log作为查询源,需要开启慢日志:
slow_query_log=ON
long_query_time=0
--结束END--
本文标题: percona PMM Query Analytics报“ No query classes for selected instance and time range”错
