Available in VPC
Monitoring supports five types of dashboards for you to check various kinds of monitoring information on MSSQL server performance and history. Monitoring is a service included in NAVER Cloud Platform's Cloud DB for MSSQL, so it can be used without additional charges. The types of dashboards provided by Monitoring are as follows:
- DB dashboard: Monitoring information related to MSSQL servers in operation
- Query Performance: Query monitoring information for the running MSSQL Server.
- Performance: monitoring information related to the performance of MSSQL Server in operation
- DB logs: Records the occurrence time and content of all logs that occur from the MSSQL Server in operation
- Audit Logs: Records occurrence time and content of Audit logs that occur from the MSSQL server in operation
Through these five types of dashboard, you can check the average value of performance of the MSSQL server in the last year as well as the log information for the last 28 days. 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.
You can set the user to be notified when monitoring results show that a certain metric has exceeded its threshold or met specific conditions by having them recognized as events. For more information on the detailed usage for event and notification settings, see Event.
Because intuitive search and management for the MSSQL performance information is available without additional charges, we recommend utilizing the monitoring metrics provided through the dashboard for stable server operations, particularly in environments without professional database managers.
Monitoring interface
The basics of using Monitoring are as follows:
| Component | Description |
|---|---|
| ① Menu name | Shows the current menu name. |
| ② Basic features | Check details for Cloud DB for MSSQL, refresh the Monitoring page |
| ③ DB Service list | List of DB services in operation and list of MSSQL Server by service |

View Monitoring dashboards
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 only the average values. To use dashboards:
- In the VPC environment of the NAVER Cloud Platform console, navigate to Menu > Services > Database > Cloud DB for MSSQL.
- Click the Monitoring menu.
- Click the MSSQL Server to be monitored 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 in case of Performance.
- From the period selection box, click and select the period you want to search, or enter it directly.
- Check the results from the dashboard.
- To see the precise metric value of a specific point on the graphic chart, mouse over to the specific point on the graphic chart.
- To see the detailed graph, double-click the graphic chart.
- Print graphic chart: Click
, followed by Print chart - Download a graphic chart to your local PC as a file: Click , followed by 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 SVG vector image: Vector image file with the .svg extension
- Step 6, the default is the last 1 hour.
- The period in step 6 can be selected to be up to 1 year for dashboard and performance, and up to 28 days for DB logs.
From the Menu > Services > Database > Cloud DB for MSSQL > DB Server menu, click and select the server you want, and then click [Monitoring] to go directly to the page in Step 4.
DB Dashboard graphic charts
The following are some descriptions for the graphic charts configured in DB Dashboard:
| Graphic chart | Unit | Description |
|---|---|---|
| CPU Used | processor time(%) | A figure of percentage indicating the elapsed time that the processor spends executing non-idle threads |
| Execute Queries Count | batch requests/sec | Number of SQL batch requests received from the server |
Query Performance graphic charts
The following are the descriptions for the graphic charts in Query Performance:
| Graphic chart | Unit | Description |
|---|---|---|
| CPU consumption and number of memory reads compared to the number of query executions | x: Sum(sum+d(delta)_execution_count): Number of query requests during 1 minute y: Sum(sum_d(delta)_total_worker_time): CPU time consumed by the query during 1 minute (us) Bubble size: Total_logical_reads: Number of page reads (8 KB) during 1 minute |
Tuning is required for queries with high CPU consumption (y) or memory reads (bubble size) compared to the number of query executions (x) Click the bubble to see which query it represents at the bottom |
