Monitoring supports four types of dashboards, allowing you to check various monitoring information about MySQL Server performance and history. 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 the MySQL server in operation
- OS dashboard: monitoring information related to the operating system of the MySQL server in operation
- DB logs: records occurrence time and content of all logs that occur from the MySQL Server in operation
- Query timeline: query execution history of the MySQL server in operation
Through four types of dashboards, you can check the average value of MySQL server performance information within the past 1 year, logs within the most recent 60 days, and query timeline indicators within the most recent 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
You can set the user to be notified when monitoring results show that a certain indicator has exceeded its threshold or met specific conditions by having them recognized as events. For more information about usage methods for event and notification settings, see 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.

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 only the average values. The following describes how to use dashboards.
- From the NAVER Cloud Platform console, click the Services > Database > Cloud DB for MySQL menus.
- Click the Monitoring menu.
- Click the MySQL 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.
- 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 check the maximum and minimum values in the graph chart: mouse-over to the graph chart
- If you want to see the detailed graph: double-click on the graphic chart
- Print graphic chart: click
, and then click the Print chart menu. - Download a 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 SVG vector image: vector image file with the .svg extension
- Download CSV: document file with the .csv extension
, and then click the Print chart menu.Caution
- In Step 5, the default value is Select all, and in Step 6, the default value is Recent 1H.
- 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
Click the server you want in the Services > Database > Cloud DB for MySQL > DB Server menus. Then clicking the [Monitoring] button will direct you to the page in Step 4.

| Connections | connection count | Number of DB access sessions |
| Database Activity | Average activity/sec | Select, insert, update, replace, delete, call, qcache_hits activity information |
| Write QPS | Average activity/sec | Number of write queries per second |
| Read QPS | Average activity/sec | Number of read queries per second |
| Replication Delay(Standby Master, Slave) | sec | Replication delay time |
| Slow Query | total / min | Number of queries that run longer than the value specified in long_query_time (the default: 1 second) |
| Row Accesses | avg / sec | The amount of ready and write queries per second for the row of the data page |

| Binary Log Total Size | GB | Overall size of MySQL Binary Log |
| Connection Aborted | connection count | The number of client programs that was terminated abruptly and the number of failed connections to the MySQL server. |
| Replication Status | - | - In case of 1, replication status is normal - Graph can be activated only on Standby Master or Slave Server - As it is not a default value, it can be exposed by user selection |
OS dashboard graphic charts
The following are some descriptions for the graphic charts configured in OS dashboard.
| Graphic chart | Unit | Description |
|---|---|---|
| CPU Usage(%) | used | CPU usage |
| Load Average | - | Server load |
| Memory Usage(%) | used | Memory usage |
| Swap(%) | used | Generated swap memory |
| Disk Used | GB | Disk usage |
| Disk I/O | MB/sec | Generated disk input/output per second |
| Network I/O | MB/sec | Generated network input/output per second |
| Free Memory | GB | Free memory space (sum of free space and buffer cache) |
| Free Storage Space | GB | Free storage space |
DB logs graphic charts
The following are the descriptions for the graphic charts configured in DB logs.
| Field | Description |
|---|---|
| Event occurrence time | Time when DB log occurred |
| Log content | DB log content |
Note
In DB logs, you can check the error log, slow log, general log, and audit log of the MySQL server in operation. However, for slow query, you need to change the value of log_min_duration_statement in DB Config to a value (ms) other than the default value (-1).
