## AMALTHEA Trace Database Metrics Viewer

This is a simple viewer that shows how to access the AMALTHEA trace database.

The ATDB metrics viewer displays metrics in three tabs: “Process Time Metrics”, “Runnable Time Metrics”, and “EventChain Time Metrics”. The table in each tab displays various time metrics (depending on what events were actually in the source trace). The time metrics are aggregated, i.e., Minimum, Maximum, Average, and Standard Deviation values of the entity instances are shown. For better navigability you can collapse the metric value rows per entity. The following figure shows the metric table for processes:

And the next picture shows the same table with the metrics of “Task_1” and “Task_2” collapsed.
