For more information, see [Observe and troubleshoot with Gemini assistance](/sql/docs/mysql/observe-troubleshoot-with-gemini).\n\nView the System insights dashboard\n----------------------------------\n\nTo view the System insights dashboard, do the following:\n\n1. In the Google Cloud console, go to the **Cloud SQL Instances** page.\n\n [Go to Cloud SQL Instances](https://console.cloud.google.com/sql)\n2. Click the name of an instance.\n3.\n Select the **System insights** tab from the SQL navigation panel on the left.\n\nThe System insights dashboard opens.\n\n\u003cbr /\u003e\n\n**Figure 1.** Dashboard image showing events timeline and summary cards.\n\n\u003cbr /\u003e\n\nThe System insights dashboard shows the following information:\n\n1. Your instance details\n\n2. [Events timeline](/sql/docs/mysql/use-system-insights#events_timeline):\n shows the system events, in a chronological order.\n This information helps you evaluate the impact of system events on the health\n and performance of the instance.\n\n3. [Summary cards](/sql/docs/mysql/use-system-insights#summary):\n provide an overview of the instance health and performance by displaying the\n latest and aggregated values for the CPU utilization, disk utilization, and\n log errors metrics.\n\n4. [Metrics charts](/sql/docs/mysql/use-system-insights#metrics): show the\n information about the operating system and database metrics that help you gain\n insight into several issues, such as throughput, latency, and cost.\n\nThe dashboard offers the following high-level options:\n\n- To create a customized dashboard, click **Customize dashboard**.\n\n\u003c!-- --\u003e\n\n- To keep the dashboard up to date, enable the\n\n **Auto Refresh** option. When you enable **Auto Refresh**, the dashboard data\n updates every minute. This feature isn't compatible with customized time\n periods.\n\n- The time selector shows `1 day` selected by default. To change the period,\n select one of the other predefined periods or click **Custom** and define a\n start and end time. Data is available for the last 30 days.\n\n- To create an absolute link to the dashboard, click the **Copy Link** button.\n You can share this link with other Cloud SQL users who have the same\n permissions.\n\n- To create an alert for a specific event, click notifications **Notification**.\n\n- To display specific alerts, click **Annotations**.\n\nSummary cards\n-------------\n\nThe following table describes the summary cards displayed at the top of the System\nInsights dashboard. These cards provide a brief overview of the instance's health\nand performance during the chosen time period.\n\nMetrics charts\n--------------\n\nThe toolbar on each chart card provides the following set of standard options:\n\n- To view metric values for a specific moment in the selected period, move the\n cursor over the chart.\n\n- To zoom in on a chart, click the chart and drag horizontally along the x-axis\n or vertically along the y-axis. To revert the zoom operation, click\n **Reset zoom**. Or, click one of the predefined time periods at the top of the\n dashboard. Zoom operations apply at the same time to all charts on a dashboard.\n\n- To view additional options, click *more_vert*\n **More chart options**. Most charts offer these options:\n\n - To view a chart in full-screen mode, click **View in full screen** . To exit\n full-screen mode, click **Cancel**.\n\n - Hide or collapse the legend.\n\n - Download a PNG or CSV file of the chart.\n\n - **View in Metrics Explorer** . View the metric in [Metrics Explorer](/monitoring/charts/metrics-explorer).\n You can view other Cloud SQL metrics in the Metrics Explorer after\n selecting the **Cloud SQL Database** resource type.\n\n- To create a custom dashboard, click *edit*\n **Customize dashboard** and give it a name. Or, expand the **Predefined** menu\n and select an existing custom dashboard.\n\n- To view a metric chart's data in detail, click *query_stats*\n **Explore data**. Here, you can filter specific metrics and choose how the\n chart displays:\n\n To save this customized view as a metric chart, click **Save to dashboard**.\n\nDefault metrics\n---------------\n\nThe following table describes the Cloud SQL metrics that appear by default\non the Cloud SQL System insights dashboard.\n| **Note:** Cloud SQL for MySQL instances with more than 500 databases report a single aggregated value for database metrics.\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nFor more information, see [Cloud SQL metrics](/sql/docs/mysql/admin-api/metrics).\n\nEvents timeline\n---------------\n\nThe dashboard provides the details of the following events:\n\nWhat's next\n-----------\n\n- [About instance settings](/sql/docs/mysql/instance-settings)\n- [Cloud SQL metrics](/sql/docs/mysql/admin-api/metrics)\n- [REST Resource: instances](/sql/docs/mysql/admin-api/rest/v1beta4/instances)"]]
