Monitoring supports four types of dashboards, enabling you to check various monitoring information for MySQL Server performance. Monitoring is a service included in NAVER Cloud Platform's Cloud DB for MySQL, so it can be used without additional charges. The types of dashboards provided by Monitoring are as follows.
- DB dashboard: Monitoring information related to MySQL Servers in operation
- OS dashboard: Monitoring information related to the operating system of MySQL Servers in operation
- DB logs: Records occurrence time and content of all logs that occur from MySQL Servers in operation
- Query timeline: Query execution history of MySQL Servers in operation
Through these four types of dashboard, you can check the average value of MySQL Server performance information within the last year, logs within the last 60 days, and Query Timeline metrics within the last 72 hours. Each dashboard is configured with various graphic charts. You can utilize these charts in your business by printing specific graphic charts or downloading them to your local PC as files using various extensions.
Note
When a certain indicator exceeds the threshold or satisfies specific conditions from the result of monitoring, you can set it up so that it is recognized as an event and the user is notified about it. For detailed usage methods for event and notification settings, please refer to Event.
Since the intuitive search and management for the MySQL performance information is available without additional charges, if you wish to operate servers stably in an environment without a professional database manager, then we recommend utilizing the monitoring indicators provided through the dashboard.

Check monitoring dashboard
The dashboards provided by monitoring consist of multiple graphic charts. You can display and intuitively check only the information you need from the dashboard of each server. The information shown in the dashboard is collected every minute to be displayed, but it shows the average values. The following describes how to use the dashboards.
- From the NAVER Cloud Platform console, click the Services > Database > Cloud DB for MySQL menus, in that order.
- Click the Monitoring menu.
- Click the MySQL Server you want to monitor from the list of DB services.
- Click the button for the dashboard you want to check from the page on the right.
- Click and select all graphic charts you want to display and check on the dashboard.
- From the Period or Search time selection box, click and select the period you want to search, or enter it directly.
- Check the results from the dashboard.
- If you want to see the precise indicator value of a specific point on the graphic chart: Mouse-over to the specific point on the graphic chart.
- If you want to see the maximum and minimum values in a graph chart: Mouse-over to the specific point on the graphic chart.
- If you want to see the detailed graph: Double-click with the mouse on the graphic chart.
- Print graphic chart: Click
, and then click the Print chart menu. - Download graphic chart to your local PC as a file: Click , and then click the file extension menu for the file you want to download.
- Download PNG image: Image file with the .png extension
- Download JPEG image: Image file with the .jpeg extension
- Download PDF document: Document file with the .pdf extension

- Download CSV: Document file with the .pdf extension
Caution
- In Step 5, the default value is Select all, and in Step 6, the default value is 1 day.
- In Step 6, you can select a period of up to 1 year for DB Dashboard and OS Dashboard, up to 60 days for DB Log, and up to 72 hours for Query Timeline.
Note
From the Services > Database > Cloud DB for MySQL > DB Server menu, click and select the server you want, and then click the [Monitoring] button to go directly to the page in Step 4.
