In order to help you better discover problems and protect your business, TDSQL-C for MySQL has optimized the aggregation method of certain monitoring metrics. Such metrics will be aggregated in MySQL's native SUM method, which will cause the metric data volume to increase. We recommend you promptly check out the corresponding changes of metrics and alarm configuration.
