title: What is equivalent of doOnSuccess method from Mono in Flux?
body: <p>In my previous version of API, I have used <strong>Mono</strong> as a return type. When everything works fine, I logged in <strong>doOnSuccess</strong> method. </p>
  
  <p>After the API method return type was changed to <strong>Flux</strong>, I cannot use the <strong>doOnSuccess</strong> for logging. </p>
