For a complete understanding of a metric value, it is important to consider not only the metric calculation, but also the interval of the data and how the metric impacts viewer experience. You can use this page to learn about Conviva's metric intervals and click a link to a specific metric definition.
Highlight Conventions:
Proper metric names are highlighted with italic and initial upper case. The components of the metric definitions and metric events are highlighted with italics.
Conviva Metric Intervals
Real-Time Data
Conviva continuously calculates real-time data based on a continuous stream of heartbeats from devices used by active viewers. Each data point aggregates the previous 60 seconds of data collected. In our Pulse user interface, real-time data is refreshed every 2 seconds.
Remove Data Dip for Partial Data in the Last Time Series Data Bucket
Note: Removes the last partial data bucket by dropping any partial data in the last time series data bucket if there is a delay in data ingestion, no data availability from the source, or only partial data available in the data bucket, based on the selected granularity and the specified date and time range.
For example, the date picker sets the range from 14 July at 1:30 pm to 14 July at 4:37 pm with a granularity of 5 minutes. The last time series data bucket spans from 4:35 pm to 4:37 pm, resulting in only 2 minutes of data, which would likely cause a dip in the time series due to partial data availability. Therefore, the partial data in that data bucket, which would cause an observable drop or dip in the last data bucket in the time series, is no longer shown.
Interval Data
Conviva computes Live, 1-minute, hourly, and other interval data, and aggregates data for longer intervals.
Interval |
Data History |
Live | 10-second data intervals, across 15-min data window. |
2 Hour Data |
2-hour data intervals for up to any 30-day period within the last 13 months |
1 Day Data |
Daily data intervals for a period greater than 30 days within the last 13 months |
1 Month Data |
Monthly data intervals for a period greater than 30 days within the last 13 months. |
For Trends page granularity, see Time Granularity.
For aggregated data, a session is counted toward a metric in different intervals depending on the metric type.
Metric Type |
Aggregation Interval |
---|---|
Started Metrics |
Metrics based on plays that started in that interval, for example VST and Plays. |
Ended Metrics |
Metrics based on plays that ended in that interval, for example Unique Devices and VPF. |
For aggregated data, metric aggregation occurs in different intervals depending on the metric type.
Metric Type |
Aggregation Interval |
---|---|
Interval Metrics |
Metrics based ongoing events that occur in that interval, for example Concurrent Plays and Rebuffering Ratio. |
Lifetime Metrics |
Metrics based on a complete session, for example the Play Duration vs Rebuffering Ratio Distribution used to further analyze the Rebuffering Ratio metric. |
Dashboard Interval Display
Most pages display computed 1-minute data intervals, along with the option to display data aggregated for 2-hour, 1-day, and 1-month intervals.
Session Timeout/Expiration
Sessions expire if no heartbeats are received for more than 120 seconds.
Session Expiration and Revived Session Handling
If a session does not receive a heartbeat for 120 seconds (2 minutes), Conviva generates a session expired event and treats the session as ended. Session expired events appear in the Viewer Timeline.
If the session revives after a 120 second lapse in heartbeats and restarts sending additional heartbeats, the Conviva continues to monitor the session and considers the revived session a separate session, but with the same session ID.
The session start time distinguishes the sessions having the same session ID. Metrics and event durations are computed separately for the initial and revived sessions. These metric differences for a revived session (that is, a continuously-monitored session that follows a prior expired session with the same session ID) are noted in the metric dictionary definitions and include:
-
Revived sessions don’t contribute to VST, because their startup behavior is often unusual.
-
Revived sessions that fail to play don’t contribute to any metrics, including VSF and EBVS.
-
Revived sessions that play successfully contribute to Attempts and Plays.
Note: Sessions are not expired or ended based on rebuffering time. Sessions “stuck” in rebuffering for a long time (for example, sessions with continuous rebuffering of more than 90 seconds in a long buffering state) don’t contribute to rebuffering metrics.
Metric Mutability for CDN and Resource Dimensions
When filtering by CDN and Resource dimensions, the displayed metric totals depend on the metric mutability type when more than one CDN/resource was used during the session.
As a result, the metric totals in Trends may not match the sum of each of the CDN/Resource metrics with different mutability types, such as Attempts with Ended Plays, Plays, Interval Playing Time.
