Creating a Dashboard

Precautions

• Preset dashboard templates are saved in the built-in group, including the cloud service and application templates. Preset dashboards cannot be deleted. Their groups cannot be changed. Dashboard templates cannot be created.
• Up to 50 dashboard groups can be created in a region.
• Up to 500 dashboards can be created in a region.
• A maximum of 30 graphs can be added to a dashboard.
• A maximum of 12 resources can be added to a digit graph. Only one resource can be displayed. By default, the first resource is displayed.
• A maximum of 10 threshold rules can be added to a threshold 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. On the menu bar, choose Monitoring Center.
2. In the navigation pane, choose Dashboard.
3. Click next to Dashboard to create a dashboard group.
4. Click Add Dashboard in the upper left corner of the list.
5. In the displayed dialog box, set parameters.

   Table 1 Parameters for creating a dashboard

   Parameter	Description
   Dashboard Name	Name of a dashboard. Enter a maximum of 255 characters. The following special characters are not allowed: "$# %&'+;<=>?\
   Group Type	Options: Existing and New. Existing: Select an existing dashboard group from the drop-down list. New: Enter a dashboard group name to create one.

6. Click OK.

Adding a Graph to a Dashboard

1. In the navigation pane, choose Dashboard.
2. In the dashboard list, locate the target dashboard.
3. Go to the dashboard page, and select the Prometheus instance for which you want to add a graph from the drop-down list.
4. Go to the dashboard page. Click Add Graph or in the upper right corner to add a graph to the dashboard. For details about the graphs that can be added to the dashboard, see Graph Description. The data can be metric or system data. Select a graph as required.

   Table 2 Parameters for adding a graph

   Data Source	Adding Mode	Scenario
   Metric Sources	See Add a metric graph.	Monitors infrastructure metrics.
   System Graphs	See Add a system graph.	Monitors service alarms, or threshold, host, or component status.

   • Add a metric graph. Set parameters by referring to Table 3. Then, click Add to Dashboard.

     Table 3 Adding a metric graph

     Parameter	Description
     Graph Title	Title of a graph to distinguish it from other graphs. Enter a maximum of 255 characters. The following special characters are not allowed: "$# %&'+;<=>?\
     Data Source	Click Metric Sources and select metric data as the source.
     Graph Type	Options: line, digit, top N, table, bar, and digital line.
     Metric List	Add metrics as required. There are four modes to add metrics: Metric type: All metrics: Select desire metrics from all metrics. When this mode is selected, enter keywords to search for metrics. Resource type: Select your target resource from the resource tree and select a metric. In this mode, you can select the same metric of multiple resources at the same time. Prometheus statement: Enter a Prometheus command and select your target metric. For details, see Prometheus Statements. Click Add Metric to add up to 12 metric data records. NOTE: When All metrics is selected, enter keywords to search for metrics. Scope: Metric monitoring scope. The scope is in the key-value pair format. Directly select an option from the drop-down list or use AND, OR, and NOT to specify scopes for metrics. Group Condition: Aggregate metric data by the specified field and calculate the aggregation result. Options: Not grouped, avg by, max by, min by, and sum by. For example, avg by clusterName indicates that metrics are grouped by cluster name, and the average value of the grouped metrics is calculated and displayed in the graph.
     Graph Settings	Configure the graph settings by referring to Metric Data Graphs (Line/Digit/Top N/Table/Bar/Digital Line Graphs).
     Statistic	Method used to measure metrics. Options: Avg, Min, Max, Sum, and Samples.
     Statistical Period	Interval at which metric data is collected. The available statistical period options vary according to the time range you select. For details, see What Is the Relationship Between the Time Range and Statistical Period?.
     Time Range	Time range in which metric data is collected. Options: Last 30 minutes, Last hour, Last 6 hours, Last day, Last week, and Custom.
     Refresh Frequency	Interval at which the metric data is refreshed. Options: Refresh manually, 30 seconds auto refresh, 1 minute auto refresh, and 5 minutes auto refresh.

   • Add a system graph. Set parameters by referring to Table 4. Then, click Add to Dashboard.

     Table 4 Adding a system graph

     Parameter	Description
     Graph Title	Title of a graph, which is used to distinguish it from other graphs. Enter a maximum of 255 characters. The following special characters are not allowed: "$# %&'+;<=>?\
     Data Source	Click the System Graphs tab and then select Alarm Statistics, Threshold Status, Host Status, or Component Status as the data source.
     Graph Settings	Alarm Statistics: Set the graph by referring to Alarm Statistics Graphs (Ring). Threshold Status: Select up to 10 threshold rules from the threshold rule list. The selected threshold data will be displayed in a table. NOTE: Ensure that metric alarm rules have been created. Otherwise, threshold status graphs cannot be added. If you select Host Status, select target hosts from the application tree. Up to 10 host monitoring data records can be added. If you select Component Status, select target components from the application tree. Up to 10 component data records can be added.

5. Click . The graph is successfully added to the dashboard.
