The COLLECT command takes a snapshot of current tracing activity.
Format:
COLLECT [qualifier]
If you start tracing with a START/NOCOLLECT command, the collected trace
records are copied to an internal CTF buffer. When the buffer is full,
new trace records overwrite the oldest trace records in the buffer.
Thus, the buffer provides a snapshot of the most recent trace history.
When you issue a COLLECT command, the current contents of the buffer
are then processed as they normally are for live or detached tracing.
