Filtering Sessions
Session Filters help you find the most actionable and insightful sessions.
Palette requires filtering metrics by the following fields:
| Field | Description | Operators |
|---|---|---|
| Sum | The sum of the metric's value during the session | >, <, =, >=, <= |
| Avg | The average value of the metric during the session | >, <, =, >=, <= |
| Max | The maximum value of the metric during the session | >, <, =, >=, <= |
Session Filters help find sessions that match a specific criteria.
| Question | Filter Example | Filter |
|---|---|---|
| Filter sessions where performance was consistently bad | Filter sessions where the sum longtask duration of the session is greater than 100ms | MetricSum > 100 |
| Filter sessions with worst case performance | Filter sessions where the max of longtask duration of the session is greater than 1000ms | MetricMax > 1000 |
Profile Aggregate Filters are automatically applied to Sessions. For example, if you want to filter sessions by a specific tag, you can do so by filtering profiles by that tag.
Sorting Sessions
Palette allows sorting sessions by Sum and Max. By default, sessions are sorted by Sum.
When listing sessions, Palette defaults to sorting sessions by the sum of that metric in the session. For example, a session with three 100ms longtasks will be above a session with one 200ms longtask. When sorting by Max, the session with one 200ms longtask will be above the session with three 100ms longtasks.
