DBbrain allows you to customize the monitoring dashboard and link, compare, and view the monitoring data of multiple instances and metrics.
Note:
Currently, the monitoring dashboard feature is supported for TencentDB for MySQL (excluding basic single-node instances), TDSQL-C for MySQL, self-built MySQL, TencentDB for Redis, and TencentDB for MongoDB.
Creating a Dashboard
1. Log in to the DBbrain console and select Monitoring and Alarming > Intelligent Monitoring on the left sidebar. On the displayed page, select a database type and an instance at the top, and select the Monitoring Dashboard tab.
2. Click Create Dashboard, enter the dashboard name, select the monitoring metrics for comparison, add an instance, and click Save.
Finding/Editing/Deleting a Dashboard
Log in to the DBbrain console and select Monitoring and Alarming > Intelligent Monitoring on the left sidebar. On the displayed page, select a database type and an instance at the top, and select the Monitoring Dashboard tab.
Click the dashboard name drop-down list to switch between different monitoring dashboards.
After selecting a dashboard, click Edit to modify its monitoring metrics and instance.
Click Delete to delete the current dashboard.
Viewing Dashboard Details
Enabling chart interaction
1. Log in to the DBbrain console and select Monitoring and Alarming > Intelligent Monitoring on the left sidebar. On the displayed page, select a database type and an instance at the top, and select the Monitoring Dashboard tab.
2. Toggle on Chart Interaction on the right to link and compare the monitoring views of multiple instances or metrics.
When you hover over a data point in any monitoring view, the data at the same time point will be displayed in other monitoring views. Click the data point to pin it for display. To unpin it, click Deselect the Time Point.
Switching between one-column and two-column modes
1. Click the button on the right of Chart Interaction in the top-right corner to switch.
2. Click the border of a monitoring view to drag it to the desired position.
Switching between real-time and historical views
Click Real-Time or Historical to view the real-time or historical monitoring view.
The real-time monitoring view displays the performance metric comparison of the instance in the last three minutes and is automatically refreshed by default. You can click Disable refresh to stop refreshing the monitoring data in real time.
In the historical monitoring view, you can select a time range (Last hour, Last 3 hours, Last 24 hours, Last 7 days, or a custom time range) to display the monitoring dashboard in the selected time range.
