Tracing Dashboards

Application Service Dashboards

Service and Application dashboards are available as two Explore hierarchies. You can access them in the Explore By drop down menu.

The Application Service View groups services into higher-level applications based on the application=[app-name] custom tag that you may add to your tracing data if you want to leverage it fully. If not present, all services will belong to a "default" application. See how to modify the attributes of your spans. The third level shows the top 50 most active operations executed on the service.

The Service Application View takes a contrary approach, displaying services by top level and breaking down their health by application. This view is especially useful for shared services that support more than one application. The third level shows the top 50 most active operations performed on the selected service and application.

Services need to be active in the last 15 minutes to appear on the list. Recent inactivity will result in a grayed-out list entry.

Tracing metrics retention has default metrics retention.

Each dashboard is a fully customizable set of panels based on automatically generated metrics using tracing data as input. You can get insight into microservice health by looking at stats from:

  • Latency: (real-time average) the average time it takes for entry spans for that service to complete. Apart from average you can also select p99, p95, p90, p50 options in service_latency_type filter to view other percentile aggregations.
  • Requests: (real-time counter) the number of entry spans reported by the service
  • Errors:  (real-time counter) the number of entry spans for the service that finished with an error

By clicking on any data point on the chart, just like for any other Sumo Logic dashboard, you can view the side panel's Infrastructure tab to drill down to related metrics or traces for the selected service.

Dashboard Panels

Add Service Map and Trace List panels to explore your application environment and review all traces directly through your Dashboard. Duplicate or add multiple panels with different filtering or queries to refine views and support your organization. 

See the Dashboard (New) guide for additional information and options to create panels, configure filters, create and filter with template variables from dashboard headers, and more.

  3. Select from the drop-down menus to filter the Service Map by the following:
    • Application if your tracing data has the application=[app-name] tag
    • Service 
    • To pass the variables from dashboard filters, set application={{application}} and/or service={{service}}
  4. Do not set the time. Service Map always shows last 72h of data.

  5. The Chart Type is set to Graph.

  6. Click the General tab to edit the Panel Details. Enter a name for the panel, set a Title Font Size, and add a short Description.
