Graph Description

Metric Data Graphs

Metric data graphs support the following types: line, number, top N, table, bar, 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.

  Table 1 Line graph parameters

  Category	Parameter	Description
  -	X Axis Title	Title of the X axis.
  	Y Axis Title	Title of the Y axis.
  	Fit as Curve	Whether to fit a smooth curve.
  	Hide X Axis Label	Whether to hide the X axis label.
  	Hide Y Axis Label	Whether to hide the Y axis label.
  	Display Background	If this option is enabled, the background will be displayed in the line graph.
  	Y Axis Range	Value range of the Y axis.
  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.

• Digit graph: highlights a single value. It can display the latest value and the growth or decrease rate of a resource in a specified period. Use this type of graph to monitor the latest value of a metric in real time.

  As shown in the following figure, you can view the CPU usage of the host in real time. 2.85% indicates the latest CPU usage, and -0.08% indicates the decrease rate in the current monitoring period.

  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.

  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.

  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.

  Table 5 Bar graph parameters

  Category	Parameter	Description
  -	X Axis Title	Title of the X axis.
  	Y Axis Title	Title of the Y axis.
  	Hide X Axis Label	Whether to hide the X axis label.
  	Hide Y Axis Label	Whether to hide the Y axis label.
  	Y Axis Range	Value range of the Y axis.
  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.

• Digital line graph: a trend analysis graph. It shows the change of a group of ordered data (usually in a continuous time interval) and intuitively displays related data analysis. It can display the latest data and the growth or decrease rate of the resource in a specified monitoring period. Use this type of graph when you need to monitor the metric data trend of one or more resources within a period.

  As shown in the following figure, the CPU usages in different periods are displayed in the same graph. 2.93% indicates the latest CPU usage, and 0.00% indicates the growth rate of the CPU usage in the current monitoring period.

  Show Legend	Whether to display legends.
  Hide X Axis Label	Whether to hide the X axis label.
  Hide Y Axis Background Line	Whether to hide the Y axis background line.
  Show Data Markers	Whether to display the connection points.
