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. Titles of metric data graphs can be customized.

  You can use a line graph to compare the same metric of different resources. The following figure shows the CPU usage of different hosts.

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

  The following figure shows the latest CPU usage.

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

The statuses of thresholds, hosts, and components can be displayed. The statuses of one or more threshold rules, hosts, or components can be added in one graph for monitoring. Titles of health status graphs can be customized.

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

  Before adding a threshold-crossing status graph, create a threshold rule. Otherwise, the threshold-crossing status graph cannot be added.

• Host status graph: monitors the health status of hosts in real time.
  Figure 4 Host status graph
  
• Service status graph: monitors the service status in real time.

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 100 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 ten threshold rules can be added to a threshold-crossing status graph.
• A maximum of ten hosts can be added to a host status graph.
• A maximum of ten components can be added to a component status graph.

Creating a Dashboard

1. Log in to the management console.
2. Under Application, click Application Operations Management.
3. In the navigation pane, choose View Management > Dashboard.
4. On the Dashboard page, click Create Dashboard. In the displayed dialog box, enter a dashboard name and click OK.
5. Add a metric graph to the dashboard.
   

   Before adding a threshold-crossing status graph, create a threshold rule. Otherwise, the graph cannot be added.

   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 Statistic Method and Statistical Cycle, and click OK.

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

   The Auto Refresh () option in the upper right corner of the Dashboard page can be enabled to automatically refresh all graphs in the dashboard.

   • On (default)

     Data in the dashboard is automatically refreshed every minute.

   • Off

     Data in the dashboard is not automatically refreshed.

More Operations

After creating a dashboard, you can also perform the operations described in Table 1.

	Save as	Click More in the upper right corner of the Dashboard page, and choose Save As, Rename, or Delete from the drop-down list.
	Rename
	Delete
	Export a monitoring report	Click Export Monitoring Report to export only line graphs in the dashboard as CSV files to a local PC.
Metric graph	Add	Click Add Metric Graph to add a line graph, digit graph, threshold-crossing status graph, host status graph, or service status graph to the dashboard.
	Modify	Choose Modify Copy, Delete, or View Larger (support only for line graphs) from the Operation drop-down list. Figure 6 Metric graph NOTE: In a dashboard, when resources such as hosts and services are deleted, metric graphs created for these resources are not automatically deleted. To improve system performance, manually delete unnecessary graphs.
