   @xuemengran nvm.  I guess you meant the PR suggested here.  I tried that; 
the log table has changed, and I couldn't match the information easily.  The 
`execution_date` column is None when `event="cli_task_run"`, which makes 
filtering impossible.
   
   I understand why the PR was rejected.  For cases where the logs exist but 
the web UI couldn't locate the correct hostname, the issue is that the 
"task_instance" table only stores the latest `try_number`/`hostname` for a task 
run (as already indicated by @ITriangle).  The PK doesn't include `try_number`. 
 It's better to fix the task_instance table, which is more fundamental, and 
probably would intimidate most "amateurs" (like me).
