The performance trends feature of DBbrain not only supports the selection of multiple performance metrics such as key metrics, all metrics, and custom metrics, but also supports multiple ways to view performance trends, such as fine-grained view of one single performance metric trend, link comparison view of multiple performance metric trends, and time comparison view of multiple performance metric trends.
Note:
Currently, the performance trends feature is supported only for TencentDB for MySQL (excluding the basic single-node instance).
The performance trends feature supports selection of multiple performance metrics, including 4 categories (Resource Monitoring, MySQL Server, InnoDB Engine, and MySQL Replication) and 15 subcategories. You can select different metrics based on different OPS needs to view the performance trends of the selected instance against the selected metrics.
Note:
Click Apply to all instances to apply the selected metrics to all database instances.
The performance trends feature currently supports the following performance metrics:
