You can check the operation trend of the key metrics of the database over time and trace the performance. You can check the current active session data and distinguish the long-running sessions.

Comparison between count trends

Home > Select Project > Analysis > Counts Trend Comparison

You can compare the count trends for different dates.

1. Select the desired instances from the Instance area. You can also select different instances.

2. Set values for Reference Date and Comparison Date.

3. Select .

Using the chart and active session area

Select on the screen. In the Layout setting window, set it to 1 x 3 and then select Save. Time must be set to Last 24 hours. You can see the database key metrics in detail for the day, as follows:

• In Time, set a desired time interval.

  • If you select the date and time, you can set the desired time in detail. After configuration, select Confirm.

• Instance: You can select an instance that is connected with the project.

• If you click a specific time point of the metrics chart, the (number3) area appears with red lines and the collected active sessions can be also displayed.

• To change the metrics in the chart, select on the upper right.

• The active session data is collected every 5 seconds. You can search the data by selecting the 5-second cells at the bottom of the screen.

• To move the time by 1 minute, select or .
