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 (New) Graphs. The data can be metric or log data. Select a graph type as required.
   • Adding a metric graph: Set parameters by referring to Table 3 and click Save.

     Table 2 Adding a metric graph

     Parameter	Description
     Graph Name	Name of a graph to distinguish it from other graphs. For graph names, variables can be added to dynamically filter graph information. Duplicate names are supported. Enter a maximum of 255 characters. The following special characters are not allowed: "$# %&'+;<=>?\
     Data Source	The default value is Metric Sources.
     Graph Type	Options: line, digit, top N, table, bar, and digital line.
     How to Add	Add metrics as required. You can select metrics from All metrics or using Prometheus statements.
     All metrics	Select target metrics from the metric drop-down list. Calculation method: Multiple Metrics: Performs calculation for metrics and their conditions separately, and displays the results on the graph. Combined Operations: Performs calculation on multiple metrics and their conditions based on expressions, and displays the results on the graph. Metric: Select a target metric from the drop-down list. You can also directly enter a metric name in the search box and click Generate. If no metric is reported, configure one. Statistical Period: Interval at which metric data is collected. The statistical periods that are available for you to select vary according to the time range. Relationship Between the Time Range and Statistical Period Condition: Metric monitoring scope. Each metric condition is in "key:value" format and can be selected from the drop-down list. You can also enter a dimension name and value, and click Generate to add a metric condition. You can also click and 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. Formatted Legend Name: Use a fixed name or variable as the legend name. Format: {{dimension name}}. If the displayed legend name is {{dimension name}}, there is no dimension. For example, enter {{hostname}} and a host name will be displayed as the legend name. Tables and digit/line graphs do not support Formatted Legend Name. You can click Add Metric to add more metrics. A maximum of 100 can be added.
     Prometheus statement	Add metric data by entering a Prometheus statement related to the metric. Prometheus Statement: See Prometheus Statements. Formatted Legend Name: Use a fixed name or variable as the legend name. If the displayed legend name is {{dimension name}}, there is no dimension. Format: {{dimension name}}. For example, enter {{hostname}} and a host name will be displayed as the legend name. To add more metrics, click Add Prometheus Statement. You can add 100 metrics in total.
     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.
     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.

   • Adding a log graph: Set parameters by referring to Table 3 and click Save.

     Table 3 Adding a log 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 Log Sources.
     Log Group	Select a desired 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 5.
     Log Stream	Select a desired 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 5.
     Go to Old Version	Click Back to Old Version to add a log graph of the old version. For details, see Adding a Log Graph.
     Time Range	Options: From now, From last, and Specified. From now: queries data generated in a time range that ends with the current time, such as the previous 1, 5, or 15 minutes. For example, if the current time is 19:20:31 and 1 hour is selected as the relative time from now, the graphs on the dashboard display the data that is generated from 18:20:31 to 19:20:31. From last: queries data generated in a time range (on the hour) that ends with the current time, such as the previous 1 or 15 minutes. For example, if the current time is 19:20:31 and 1 hour is selected as the relative time from last, the graphs on the dashboard display the data that is generated from 18:00:00 to 19:00:00. Specified: queries data that is generated in a specified time range.
     Refresh Frequency	Interval at which the data is refreshed. Options: Refresh now, Refresh every 30 seconds, Refresh every 1 minute, and Refresh every 5 minutes.
     Graph Type	Options: line, digit, table, bar, digital line, pie, and map graphs.
     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 Log Data Graphs.
     Interactive mode	Metrics	Use a statistics function on a selected field to calculate your desired metric. You can select an option from the drop-down list. Options: Log count, Aggregation statistics, and Estimation function. Log count: count(*), Logs with non-null field values, Logs with non-zero field values, and Logs with different field values Aggregation statistics: max(), min(), avg(), sum(), earliest(), and latest(). Estimation function: Median and Percentile
     	Alias	Alias of a metric. After setting an alias, it takes precedence.
     	Conditions	Conditions for filtering metric data. A condition comprises a field and a value. The field can be selected directly from the drop-down list. Multiple conditions can be set using AND or OR.
     	Group	Group the values by selected field (group by), collect metric statistics by group, and sort the results by order (order by).
     	Sort
     	Copy to Syntax Mode	After setting parameters such as Metrics and Conditions in interactive mode, you can preview the search statement. By clicking Copy to Syntax Mode, you can switch to the syntax mode.
     	Format SQL	Click to set the formatting SQL statement and reverse formatting SQL statement to optimize the search statement and improve the search efficiency.
     Syntax Mode	Enter a statement in the search box to query logs. The search analysis syntax consists of the search statement and SQL analysis statement. The two statements are associated by using the pipe character (|).

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

More Operations

After a dashboard is created, you can also perform the operations listed in Table 4.

Relationship between time ranges and statistical periods (for new dashboards)

In AOM, a maximum of 1,440 data points can be returned for a single metric query. The relationship between the time range and statistical period is as follows:

Maximum time range = Statistical period x 1,440

If you select a time range shorter than or equal to the maximum time range, all the statistical periods that meet the preceding formula can be selected. For example, if you want to query metrics in the last hour, the available statistical periods are 1 minute, and 5 minutes.

For a dashboard, the relationship between the time range and statistical period is shown in the following table.
