Top Sessions

'# Samples Active' shows the number of ASH samples in which the session was found waiting for that particular event. The percentage shown in this column is calculated with respect to wall clock time and not total database activity.
'XIDs' shows the number of distinct transaction IDs sampled in ASH when the session was waiting for that particular event
For sessions running Parallel Queries, this section will NOT aggregate the PQ slave activity into the session issuing the PQ. Refer to the 'Top Sessions running PQs' section for such statistics.

Top Blocking Sessions

Blocking session activity percentages are calculated with respect to waits on enqueues, latches and "buffer busy" only
'% Activity' represents the load on the database caused by a particular blocking session
'# Samples Active' shows the number of ASH samples in which the blocking session was found active.
'XIDs' shows the number of distinct transaction IDs sampled in ASH when the blocking session was found active.

Activity Over Time

Analysis period is divided into smaller time slots
Top 3 events are reported in each of those slots
'Slot Count' shows the number of ASH samples in that slot
'Event Count' shows the number of ASH samples waiting for that event in that slot
'% Event' is 'Event Count' over all ASH samples in the analysis period
