- [`LogEvent`](http://www.javadoc.io/page/com.google.cloud.tools/jib-core/latest/com/google/cloud/tools/jib/event/events/LogEvent.html) - Log message events. The message and verbosity can be retrieved using `getMessage()` and `getLevel()`, respectively.
- [`TimerEvent`](http://www.javadoc.io/page/com.google.cloud.tools/jib-core/latest/com/google/cloud/tools/jib/event/events/TimerEvent.html) - Events used for measuring how long different build steps take. You can retrieve the duration since the timer's creation and the duration since the same timer's previous event using `getElapsed()` and `getDuration()`, respectively.
-- [`ProgressEvent`](http://www.javadoc.io/page/com.google.cloud.tools/jib-core/latest/com/google/cloud/tools/jib/event/events/ProgressEvent.html) - Indicates the amount of progress build steps have made. Since Jib consists of a hierarchy of build steps, each progress event consists of an allocation (containing a fraction representing how much of the root allocation this allocation accounts for) and a number of progress units that indicates the amount of work completed since the previous progress event. In other words, the amount of work a single progress event has completed (out of 1.0) can be calculated using `getAllocation().getFractionOfRoot() * getUnits()`. Progress events also carries the type of its corresponding build step, which can be retrieved using `getBuildStepType()`.

Use `getBuildStepType()` to retrieve the step that the event is part of, and use `getCount()` to get the number of layers being processed.
