The Service Map is a high-level view of your application environment, automatically built from tracing data in real time as it arrives in Sumo Logic. This gives you a greater understanding of your application architecture and dependencies between monitored microservices.
To open Service Map click + New and select Service Map.
The Service Map provides the following features:
- Zoom in and out on the map.
- Hover over a service to see its connections to other services and the last 15 minutes of activity in terms of latency, requests, and errors.
- Click on a service to open the Entity Inspector with the ability to drill down to traces, metrics, and the service dashboard.
- Filter by application, if your tracing data has the
- Search for a service by name.
Color of services
The color of services is based on automatic (default) or manual thresholds you can configure in the settings menu. Red indicates an anomaly and blue indicates normal activity.
Shape of services
Remote services, like databases or external calls, automatically detected in client traffic, even without actual direct instrumentation, are visualized using the cloud icons instead of circles.
The Service Map shows activity between services and their presence from the last 72 hours, however, if the service or connection was inactive for more than one hour, it is displayed with dashed lines.
Size of services
The size of services on the map is based on how active they are, where large circles are more active compared to small circles that are less active.
Settings are user-specific and preserved in your browser's Local Storage, so each user can have their own specific settings to view Service Map health indicators. The settings menu opens by clicking the gears icon in the top-right corner of the map.
Automatic anomaly detection is enabled by default. A service is displayed in a red circle if at least one of the KPIs (latency, errors, requests) has an anomaly (a spike for latency and errors or dip in the case of requests) in the last 15 minutes AND the anomaly was not present 7 days ago at the same time. In the settings menu, this default option is called Worst Case. You can explicitly choose one of the KPIs instead.
The standard metric outlier operator is used to detect this. You can adjust the sensitivity and learning window of the outlier detection in the settings menu to make the logic more or less dependent on occasional spikes.
Manual anomaly detection settings allow you to specify different detection settings for each KPI. Click the toggle switch to activate these settings on and off. You can explicitly toggle each KPI as desired.
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 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.
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.
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
- 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.
Install the App
This section shows you how to install the Sumo Logic App for Tracing - Application Services Health. You need to perform this step only when you do not have existing Tracing - Application Services Health content in your Library.
To install the app, do the following:
From the App Catalog, search for and select the Tracing - Application Services Health.
If you want to see a preview of the dashboards included with the app before installing, click Preview Dashboards.
To install the app, click the Add to Library button and complete the following fields.
App Name. You can retain the existing name, or enter a name of your choice for the app.
Advanced. Select the Location in Library (the default is the Personal folder in the library), or click New Folder to add a new folder.
Click Add to Library.
Once an app is installed, it will appear in your Personal folder or the folder you specified. From here, you can share it with your organization.
