This comes from the Italian military phrase all' erta, ‘on the lookout’ or, more literally, ‘to the watchtower’. It was originally a military term in English too, before it acquired its more general meaning. Alert was first used as an adverb, so you could say that the later expression on the alert strictly means ‘on the on the lookout’.
