In Odysseus generating an altert is simply so create a data pipeline where an element reaches an final operator that sends out the value. E.g. if you use the Select operator to filter out every bid that has a lower price than 400 only bids with a value higher or equals 400 is send to the next operator. An altert can be sending an e-mail (in the following example without authentification at the SMTP server). See Transport Handlerhandler for further ways to output values.
