Metric Data Graphs (Including Line and Digit Graphs)

• Line graph: displays the metric data trend by time. Use this type of graph to monitor the metric data trend of one or more resources in a period.

  You can use a line graph to compare the same metric of different resources.

• Digit graph: displays the latest value of a metric in real time.

Health Status Graphs (Including Threshold, Host, and Component Status Graphs)

The status of thresholds, hosts, and components can be displayed. The status of one or more threshold rules, hosts, or components can be added to one graph for monitoring.

• Threshold-crossing status graph: monitors the status of threshold rules in real time.
  

  Before adding a threshold status graph, ensure that you have created a threshold rule. Otherwise, such a graph cannot be added.

• Host status graph: monitors the host status in real time.

• Component status graph: monitors the component status in real time.

Top N Resource Graphs

For top N resource graphs, the statistical unit is a cluster and statistical objects are resources such as hosts, components, or instances in the cluster. A top N resource graph shows the top N resources in a cluster in a visualized manner. Both the top 5 and top 15 resources can be displayed. By default, the top 5 resources are displayed. After the graph is zoomed in, the top 15 resources are displayed.

To quickly view the top N resources, add a top N graph to the dashboard. You only need to select resources and metrics, for example, host CPU usage. AOM then automatically singles out top N hosts for display. If the number of resources is less than N, actual resources are displayed.

• By default, the top 5 resources are displayed. To view the top 15 resources, click Top 15 xxx, double-click the graph, or click View Larger in the Operation column.
• To monitor the top 5 resources among all clusters, view them on the O&M page. Alternatively, add the corresponding graph on the O&M page to the dashboard.
• You can customize the title of the top N resource graph. By default, the title is resource type(cluster name).

Precautions

• A maximum of 50 dashboards can be created in a region.
• A maximum of 20 graphs can be added to a dashboard.
• A maximum of 10 resources can be added to a line graph, and resources can be selected across clusters.
• Only one resource can be added to a digit graph.
• A maximum of 10 threshold rules can be added to a threshold-crossing status graph.
• A maximum of 10 hosts can be added to a host status graph.
• A maximum of 10 components can be added to a component status graph.

Creating a Dashboard

1. In the navigation pane, choose Overview > Dashboard.
2. On the Dashboard page, click Create Dashboard. In the displayed Create Dashboard dialog box, enter a dashboard name and click OK.
3. Add a metric graph to the dashboard. The dashboard supports the following graphs: line graphs, digit graphs, threshold-crossing status graphs, host status graphs, and component status graphs. Select a graph that meets your requirements.
   The following shows how to add a line graph to a dashboard:

   1. On the Dashboard page, click Add Metric Graph. In the displayed Select Which to Add dialog box, click Create below Metric Data.
   2. Select the type of the graph: In the displayed Add Metric Graph dialog box, select Line graph and then click Next.
   3. Select the metrics and set Statistical Mode and Statistical Cycle, and click OK.

4. Click Save in the upper right corner of the Dashboard page.
   

   Enable Auto Refresh () in the upper right corner of the Dashboard page so that all graphs in the dashboard can be refreshed automatically.

   • On (default)

     Data in the dashboard will be automatically refreshed each minute.

   • Off

     Data in the dashboard will not be automatically refreshed.

More Operations

After creating a dashboard, perform the operations listed in Table 1 if needed.
