Metric Data Graphs

The following types of graphs are supported: line graphs, digit graphs, top N graphs, tables, bars, and digital line graphs.

• Line graph: used to analyze the data change trend in a certain period. Use this type of graph when you need to monitor the metric data trend of one or more resources within a period.

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

  Figure 1 Line graph
  

  Table 1 Line graph parameters

  Category	Parameter	Description
  Graphics	Line Shape	Line type. Options: Straight and Curved.
  	Display Background	If this option is enabled, the background will be displayed in the line graph.
  	Top Margin	Distance between the axis and the upper boundary of the graph.
  	Bottom Margin	Distance between the axis and the lower boundary of the graph.
  	Left Margin	Distance between the axis and the left boundary of the graph.
  	Right Margin	Distance between the axis and the right boundary of the graph.
  X Axis	Show	Whether to display the X axis.
  	X Axis Title	Title of the X axis.
  Y Axis	Show	Whether to display the Y axis.
  	Y Axis Title	Title of the Y axis.
  	Y Axis Range	Value range of the Y axis.

• Digit Graph: used to highlight a single value. Use this type of graph to monitor the latest value of a metric in real time.

  In the following figure, you can view the CPU usage of a host in real time.

  Table 2 Digit graph parameters

  Parameter	Description
  Show Miniature	After this function is enabled, the icon will be zoomed out based on a certain proportion. Also, a line graph is added.

• Top N: The statistical unit is a cluster and statistical objects are resources such as hosts, components, or instances in the cluster. The top N graph displays top N resources in a cluster. By default, top 5 resources are displayed.

  To 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.

  In the following graph, the top 5 hosts with the highest CPU usage are displayed.

  Figure 3 Top N graph
  

  Table 3 Top N graph parameters

  Category	Parameter	Description
  -	Sorting Order	Sorting order of data. Default: Descending.
  	Upper Limit	The maximum number of resources to be displayed in the top N graph. Default: 5.
  	Dimension	Metric dimensions to be displayed in the top N graph.
  	Column Width	Column width. Options: auto (default), 16, 22, 32, 48, and 60.
  	Unit	Unit of the data to be displayed. Default: %.
  	Display X-Axis Scale	After this function is enabled, the scale of the X axis is displayed.
  	Show Value	After this function is enabled, the value on the Y axis is displayed.
  	Display Y-Axis Line	After this function is enabled, the line on the Y axis is displayed.
  Advanced Settings	Left Margin	Distance between the axis and the left boundary of the graph.
  	Right Margin	Distance between the axis and the right boundary of the graph.
  	Top Margin	Distance between the axis and the upper boundary of the graph.
  	Bottom Margin	Distance between the axis and the lower boundary of the graph.

• Table: A table lists content in a systematic, concise, centralized, and comparative manner, and intuitively shows the relationship between different categories or makes comparison, ensuring accurate display of data.
  In the following figure, you can view the CPU usage of different hosts in a table.

  Table 4 Table parameters

  Parameter	Description
  Field Name	Name of a field.
  Field Rename	Rename a table header field when necessary.

• Bar graph: A vertical or horizontal bar graph compares values between categories. It shows the data of different categories and counts the number of elements in each category. You can also draw multiple rectangles for the same type of attributes. Grouping and cascading modes are available so that you can analyze data from different dimensions.
  In the following figure, you can view the CPU usage of different hosts in a graph.

  Category	Parameter	Description
  Graphics	Top Margin	Distance between the axis and the upper boundary of the graph.
  	Bottom Margin	Distance between the axis and the lower boundary of the graph.
  	Left Margin	Distance between the axis and the left boundary of the graph.
  	Right Margin	Distance between the axis and the right boundary of the graph.
  X Axis	Show	Whether to display the X axis.
  	X Axis Title	Title of the X axis.
  Y Axis	Show	Whether to display the Y axis.
  	Y Axis Title	Title of the Y axis.
  	Y Axis Range	Value range of the Y axis.

• Digital line graph: used to analyze the data change trend in a certain period and intuitively display related data. Use this type of graph when you need to monitor the metric data trend of one or more resources within a period.
  In the following figure, you can view the CPU usage in different periods in a graph.
