      Create a Dashboard
      CLS supports various ways to create a dashboard:
      Blank Dashboard: Create a blank dashboard that requires users to add charts manually and save them.
      Import Dashboard: Import a Json file of an existing CLS dashboard. The Json file is exported from an existing dashboard.
      Create from Dashboard Template (Recommended): CLS offers a wide range of dashboard templates. You can choose the right template according to your scenario and log content, enable it with one click, and a dashboard will be automatically generated.
      Filters and Variables
      Filters: All chart data in the dashboard can be filtered by the specified field value.
      Variables: Users can set a variable value via static input or dynamic query and apply it to search statements, titles, and text.
      Table
      A table is the most common type of data display, where data is organized for comparison and counting. It is suitable for most scenarios.
      Table
      Sequence Diagram
      A sequence diagram requires statistics to have a sequence field so that it can organize and aggregate the metrics in chronological order. It visually reflects the change trend of a metric over time. It is suitable for trend analysis scenarios, for example, analyzing the trend of the daily number of 404 errors in the past week.
      Bar Chart
      A bar chart describes categorical data. It visually reflects the comparison of each category in size. It is suitable for category statistics scenarios, for example, collecting the numbers of each type of error code in the last 24 hours.
      Bar Chart
      Pie Chart
      A pie chart describes the proportions of different types. It measures the proportion of each type by the slice size. It is suitable for proportion statistics scenarios, for example, analyzing the proportions of different error codes.
      Pie Chart
      Individual Value Plot
      An individual value plot describes a single metric, typically a key metric with business value. It is suitable for collecting daily, weekly, or monthly metrics such as PV and UV.
      Gauge Chart
      A gauge chart describes a single metric. Unlike an individual value plot, it is generally used with a threshold to measure the metric status. It is suitable for rating scenarios, such as system health monitoring.
      Map
      A map shows the geographic location of data through the position of graphics. It is generally used to display the distribution of data in different geographic locations. It is suitable for geographic statistics scenarios, such as the geographic distribution of attacker IPs.
      Map
      Sankey Diagram
      A Sankey diagram is a special type of flow diagram used to describe the flow of one set of values to another set. It is suitable for directional statistics scenarios, such as firewall source and destination IP traffic.
      Word Cloud
      A word cloud is a visual representation of the frequency of words. It is suitable for audit statistics scenarios, such as high-frequency personnel statistics.
      Funnel Chart
      A funnel chart is suitable for business processes with one single flow direction and path. It collects the statistics of each stage and uses a trapezoidal area to represent the business volume difference between two stages.
      Log
      Log charts allow you to save raw logs to the dashboard. You can quickly view the analysis result and the associated log content on the dashboard page, with no need to redirect to the search and analysis page.
      log
      Text
      Text type charts support the MarkDown syntax. You can insert text, image links, hyperlinks, etc. on the dashboard page.
      Text
      Data Conversion
      Data conversion allows you to perform further processing of search results, including modifying data types, selecting fields for chart creation, and merging groups. This satisfies your chart creation needs without modifying SQL statements.
      Unit Configuration
      Automatic unit conversion is available in charts. When you select an original unit, the value is automatically converted to the next higher unit if it meets the conversion factor. Units can be configured to display decimal places.
      Other Feature Configuration
      Interaction Event
      The chart has its interaction event feature, which allows clicking the chart content to trigger interactions such as opening up the search and analysis page, dashboard page, and third-party URL.
      Add a Group
      The dashboard supports chart grouping. Grouping allows you to categorize and collapse dashboard chart contents.

      Subscribing to Dashboard
      CLS allows you to subscribe to a dashboard and export it as an image. Daily, weekly, and monthly reports can be sent to specified recipients regularly via email or WeCom. It is available for those dashboards that need to send daily, monthly, and reports to the team.
      Chart Time Configuration
      After turning off the use of global time, the chart time is controlled independently and no longer changes with the change in global time. Different charts in the dashboard can use different time ranges, supporting more varied comparison scenarios.
