Dumping log data

`rake events:dump`

The event dump outputs a CSV with the following columns:

Timestamp
Event type
User
Event target
Event extra entity
State

The event types and their arguments are documented in the top of log_event.rb.

Note: Events with state can mean the opposite! For example share_video with state 0 means that a video was unshared.

Example output:

2016-02-16 14:52:13 UTC,publish_video,42,167,,1
2016-02-16 14:55:49 UTC,create_group,42,41,,
2016-02-16 14:59:51 UTC,share_video,42,166,41,1

`rake events:names`

Outputs names of entities used in the log dump in JSON format.

Example output:

{
  "videos": { "123": "Some video", "151": "Other video" },
  "users": { "15": "Urist McTest" },
  "groups": { "3": "Sample group" },
}

Visualization

The log data can be visualized with eventgraph.
