One thing you can do is query the ACTLOG for client-sent message ANE4959I 
telling of more than 0 files failed, which may correlate with previous ANE4037E 
messages about files changing during processing, ANE4005E file not found, and 
the like.  (If the same files show up day after day, then it's likely that the 
client administrator is not reviewing logs for issues, where the server 
administrator should best notify them.)
Similarly, the SUMMARY table contains a FAILED count.

Note that you can also do like
  select NODE_NAME, RESULTS from EVENTS where NODE_NAME is not null
to react to the return code from the client operation.
