Creating a Dashboard

Precautions

• Preset dashboard templates are listed under System, including the container, cloud service, native middleware, and application templates. Preset dashboards cannot be deleted. Their groups cannot be changed. Dashboard templates cannot be created.
• Preset container dashboards can be used only after you install kube-prometheus-stack on the Add-ons page of CCE.
• Preset native middleware dashboards can be used only after you create middleware collection tasks on the UniAgent page.
• Up to 1000 dashboard groups can be created in a region.
• Up to 1000 dashboards can be created in a region.
• A maximum of 30 graphs can be added to a dashboard.
• A maximum of 200 metric data records can be displayed in a line graph.
• Only one resource can be displayed in a digit graph.

Creating a Dashboard

1. Log in to the AOM 2.0 console.
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: "$# %&'+;<=>?\
   Enterprise Project	Enterprise project. If you have selected All for Enterprise Project on the global settings page, select one from the drop-down list here. If you have already selected an enterprise project on the global settings page, this option will be dimmed and cannot be changed.
   Bind to Application	Select an application created in CMDB to bind. NOTE: This configuration item is available only when the application monitoring function is enabled. For details about how to enable this function, see Menu Settings.
   Group Type	Options: Existing and New. Existing: Select an existing dashboard group from the drop-down list. New: Enter a dashboard group name to create one. Enter a maximum of 255 characters. The following special characters are not allowed: "$# %&'+;<=>?\

6. Click OK.

Adding a Graph to a Dashboard

After a dashboard is created, you can add graphs to the dashboard:

1. In the dashboard list, locate the target dashboard.
2. Go to the dashboard page, and select the Prometheus instance for which you want to add a graph from the drop-down list.
3. 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, log,. Select a graph as required.

   Table 2 Parameters for adding a graph

   Data Source	How to Add	Scenario
   Metric Sources	See Add a metric graph.	Monitors metrics of the business layer, application layer, Prometheus middleware, Prometheus running environments, Prometheus cloud services, open-source monitoring systems, Prometheus APIs/SDKs, and custom Prometheus plug-ins.
   Log Sources	See Add a log graph.	Monitors business metrics or other log metrics, such as latency, throughput, and errors cleaned based on ELB logs.

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

     Table 3 Adding a metric graph

     Parameter	Description
     Graph Name	Name 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 the following ways to add metrics: All metrics: Select desire metrics from all metrics. When you select metrics, you can only enter English keywords to search and only English content is displayed. In this mode, a maximum of 100 metrics can be added. Prometheus statement: Enter a Prometheus command and select your target metric. For details, see Prometheus Statements. In this mode, only one metric can be added. Click Add Metric to add up to 100 metric data records. NOTE: When All metrics is selected, enter keywords to search for metrics. Condition: Metric monitoring scope. It is in the "key:value" format. You can select a condition from the drop-down list. Select AND or OR to add more conditions for the metric. 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. Alias: Use a fixed name or variable to display. Format: {{dimension name}}. For example, {{host name}}. (Digit graphs, tables, and line graphs do not support aliases.)
     Graph Settings	On the right of the page, click the down arrow, select a desired graph type from the drop-down list, and set graph parameters (such as the X axis title, Y axis title, and displayed value). For details about the parameters, see Metric Data 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 log graph. Set parameters by referring to Table 4. Then click Save.

     Table 4 Log graph parameters

     Parameter	Description
     Graph Name	Name 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 Log Sources.
     Log Group	Select a proper log group from the drop-down list box. If there is no log group you want to select, click Add Log Group to create one. For details, see Table 6.
     Log Stream	Select a proper log stream from the drop-down list. If there is no log stream you want to select, click Add Log Stream to create one. For details, see Table 6.
     Graph Settings	Select the required field from the structured field list and click next to the field name. Use the default SQL statements in the log graph or enter related query statements in the SQL statement query area as required. Specify the statistical period of log data. Options: Last minute, Last 5 minutes, Last 15 minutes, Last hour, Last 6 hours, Last day, Last week, or Custom. Click Execute Query to query related logs. By default, log data is displayed based on the graph type you set. You can select a graph type as required. Click to display the current log data in a table. Click to display the current log data in a bar graph. Click to display the current log data in a line graph. Click to display the current log data in a pie graph. Click to display the current log data in a number graph. Click to display the current log data in a digital line graph. Click to display the current log data in a national or provincial map. You can set the display parameters under a graph. For details, see Log Data Graphs.

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