ECO Metrics

ECO provides a robust set of metrics to enable application performance monitoring and user behavior analysis across your web and native applications. Metric values appear as time series and distributions in metric widgets, and alongside dimensional values in the dimension drill-down tables. Selecting different metric widgets changes the metrics in the dimension tables. All metrics are calculated during the selected time interval.

An ECO session starts when any system or user-defined event is received and ends after 90 seconds of inactivity.

Metrics can span a specific interval or a complete session.

  • Session Metrics: Metrics based on data from events that occur throughout sessions that end within the selected time interval, for example App Video Bounce Rate metric from sessions that ended yesterday. If a session starts before the selected time interval but ends within it, the data for that session is still considered for the calculation of the session metrics.

  • Interval Metrics: Metrics based on data from events that occur within a specific interval during sessions, for example, Total Events, the cumulative count of mapped events occurring within a specific interval during sessions.

In addition to the metrics designed by Conviva to optimize your analysis, ECO supports a custom metric builder so you can create customized metrics based on your specific requirements. For more details, see Metric Builder.

Secondary Metric

As primary metrics, Conviva uses a proprietary combination of native and web applications events to provide a rich set of application performance and experience metrics. The Conviva ECO Sensor supports events, such as page_view and network_request.

Selecting a metric widget in ECO also displays a secondary metric that provides a context or related data to help you more completely understand the primary metric. Secondary metrics enhance the interpretation and analysis of primary metrics.

Secondary metrics display in the dimension panel after clicking a metric widget in the metric panel, for example Ended Session Count displays as a secondary metric for App Video Bounce Rate.

Custom Events

Event Type Semantic Mapping Metric Building Metric in App

Custom Events

  • Map raw events to unified semantics in Semantic Mapper

  • Assign event tag and event value to map events

Use mapped events to build metrics.

 

Metrics based on the mapped events appear in App pages.

Video Seek Events: For example, to track and analyze user behaviors when seeking videos, map the custom events seek_forward, seek_backward, seek_bar_dragged_forwards, and seek_bar_dragged_backwards to an event User seek action.

App Login Events: For example, to track the user login behavior and analyze the login success rate, map the event button_click with the tag key button_click_element_text and the tag value Log in to an event Login Button Click.

Conviva Video Events

Conviva video events (conviva_video_events) are also available using abbreviations as tag keys.

Metrics for Analyzing Web and Native Applications Performance

Note: If you integrate both your web and native applications with the Conviva sensor, these metrics are calculated using data from both types of applications.

Active Devices

The total number of devices that generated at least one event within sessions during the specified time interval.

Note: Why do I see difference in values for Active Devices and App Sessions? Previously, only conviva-defined events contributed towards determining whether a particular device is still active. This resulted in not capturing some of the user-defined events in the overall active-session and active-devices computation. Conviva has now made it flexible for users to define what events should be included within a session. With this enhancement, our Metrics Computation Engine now computes both user-defined and conviva-defined events to determine whether a device is Active. This enhancement will temporarily show an elevated change in metric values for Active Devices and App Sessions.
