A topology intuitively displays the relationships between nodes. In log analysis scenarios, it can be used to analyze calling relationships between services, system architecture conditions, and data stream directions.
Operation Steps
1. Log in to the Cloud Log Service (CLS) console, choose Dashboard > Dashboard List, and select the dashboard you want to view.
2. Click Add Chart, create a chart, and select Topology as the chart type.
3. Configure the chart as needed.
General Configurations
Configuration Item
Description
Basic Info
Chart Name: Set the display name of the chart, which can be empty.
Node Configuration
Node ID: The node ID field displayed for the node, selected from the source node ID or target node ID.
Displayed Node Name: Name displayed for the node. If left empty, the node ID is displayed.
Fields Displayed in Node: Field information displayed on the node. Only one field can be selected. For example, select an important monitoring metric or attribute of the node.
Fields Displayed in Node Dialog Box: Information displayed in the tooltip window triggered by clicking the node. Multiple field contents are supported.
Display Node Icon: Display an icon on the node. The chart type is mapped by the field value. The icon will overwrite the field information displayed inside the node.
Node Threshold: Select a certain metric of the node as the threshold. When the threshold condition is met, the node changes to the corresponding color. This can be used in scenarios such as node health status monitoring.
Connection Configuration
Content Displayed on Connection: Field information displayed on the connection line. Only one field can be selected, for example, the average request latency between two services.
Fields Displayed in Connection Dialog Box: Information displayed in the tooltip window triggered by clicking the connection line. Multiple field contents are supported.
Connection Width: The metric mapped to the line width, such as the traffic size between two nodes. A wider line indicates greater traffic.
Connection Threshold: Select a certain metric of the connection line as the threshold. When the threshold condition is met, the connection color changes to the corresponding color. This can be used in scenarios such as monitoring request latency between services.
Layout Configuration
Layout Type: Select the default layout type.
Display Node Name: Control whether to display the node name.
Display Thumbnails: Control whether to display the thumbnail.
Standard Configuration
Unit: Set the unit for all metric-type fields in the chart. For details, see Unit Configuration.
Decimal Places: Set the number of decimal places to retain for metric-type fields.
Interaction event
Click a data point in the chart to trigger interaction events, such as redirecting to a set URL, opening the search and analysis page, opening the dashboard page, or adding filter conditions. For details, see Interaction Event.
Statistical Analysis Fields
The source node ID field and target node ID field should be selected for a topology. You need to manually select the statistical analysis fields.
Configuration Item
Description
Source Node ID
Select the source node ID field for the topology. A pair of source and target nodes forms a topological relationship.
Target Node ID
Select the target node ID field for the topology. A pair of source and target nodes forms a topological relationship.
Statement Example
Display statistics on traffic distribution by country and ISP.
