Synchronized console data and user interface playback

A method, comprising:

• receiving, from user devices of users, console logs that specify sequences of user interface events that occurred during user sessions in which the users interacted with user interfaces presented by one or more pages of a publisher, wherein the console logs include errors generated by the user devices during the user sessions;
• for each user session of a plurality of different user sessions:
• identifying a given console log for user interface events that occurred during the user session at a user device;
• generating playback data that presents visual changes to one or more user interfaces of the publisher that occurred during the user session;
• generating and providing an interactive interface that includes (i) session replay area in which the playback data presents the visual changes to the one or more user interfaces of the publisher that occurred during the user session and (ii) a console log area that presents console entries from the given console log for the user interface events that occurred during the user session, wherein the interactive interface includes an animation that visually specifies, during playback of the visual changes to the one or more user interfaces in the session replay area, which console entries in the given console log were generated by the user device as the visual changes occurred during the user session;
• updating the interactive interface to present page speed metrics for particular milestones in loading a given page presented during the user session;
• detecting user interaction with a given page speed metric of the page speed metrics;
• and
• generating a search for user sessions using search criteria based on the given page speed metric.

A non-transitory computer readable medium storing instructions that upon execution by one or more computers cause the one or more computers to perform operations comprising:

• receiving, from user devices of users, console logs that specify sequences of user interface events that occurred during user sessions in which the users interacted with user interfaces presented by one or more pages of a publisher, wherein the console logs include errors generated by the user devices during the user sessions;
• for each user session of a plurality of different user sessions:
• identifying a given console log for user interface events that occurred during the user session at a user device;
• generating playback data that presents visual changes to one or more user interfaces of the publisher that occurred during the user session;
• generating and providing an interactive interface that includes (i) session replay area in which the playback data presents the visual changes to the one or more user interfaces of the publisher that occurred during the user session and (ii) a console log area that presents console entries from the given console log, wherein the interactive interface includes an animation that visually specifies, during playback of the visual changes to the one or more user interfaces in the session replay area, which console entries in the given console log were generated by the user device as the visual changes occurred during the user session;
• updating the interactive interface to present page speed metrics for particular milestones in loading a given page presented during the user session;
• detecting user interaction with a given page speed metric of the page speed metrics;
• and
• generating a search for user sessions using search criteria based on the given page speed metric.
