Simple Log Service:Radar chart

Last Updated:Aug 29, 2023

You can use a radar chart to visualize multi-dimensional data in Simple Log Service. This topic describes the basic configurations of a radar chart.

Background information

A radar chart can be used to compare multiple columns of data in the same dimension.

For example, the result of a query statement includes the request_method, total, avg_time, and avg_length columns. The total, avg_time, and avg_length columns indicate the total number of requests, average request time, and average request length for each request method within a specific period of time.

In this case, you can use a radar chart to visualize the preceding columns of data for each request method. Radar chart

Interaction occurrences

Interaction occurrences are configured to analyze a single field or the result of a single query statement to extract deeper value from the data. Interaction occurrences include events to open a Logstore, open a saved search, open a dashboard, open trace analysis, open trace details, and create a custom HTTP link. For more information, see Drill-down events.

For example, you can add the A > avg_length field to configure an interaction occurrence for the avg_length column in the result of Query Statement A. After you configure the Open Logstore interaction occurrence for the avg_length column in the result of Query Statement A, you can click a point on a pink connector and then click Open Logstore. You are redirected to the Logstore that you specified in the interaction occurrence.
