title: how to prevent "note : Table does not support optimize, doing recreate + analyze instead"
body: <p>my problem is that i run <code>mysqlcheck</code> for InnoDB tables in a Cronjob and if i get everytime an e-mail with thousands of these messages i will easily overlook possible error messages.</p>
  
  <p><code>--silent</code> does not help either.</p>
  
  <p>my best try till now is to 
  <code>| grep -v "note     :"</code> 
  but i fear that i could be stripping out more important "notes"...</p>
  
  <p>But even so <code>mysqlcheck</code> is listing every table in the DB which is already a pretty long list, still hiding possible error messages.</p>
  
  <p>i haven't been able to find any relevant information about exit codes of <code>mysqlcheck</code>, for instance, to just send an e-mail if there is really something wrong. </p>
  
  <p>so the question is:
  "How to run <code>mysqlcheck</code> and just get <strong>RELEVANT</strong> output"?</p>
