Nagios is pretty much a joke compared to most enterprise production monitoring tools, e.g. Wiley and Foglight. I always find it funny to read what people consider "monitoring" they're talking about a few disparate metrics and then complain that the alerting/paging sucks. If the tool can't trace a transaction end-to-end. I.e if a user visits your page or uses your application you need the ability to trace it from Http to EJB across any webservices and queues and ESB's right down to which queries were used in the database, if you can't do that you're using a shit monitoring suite. Knowing infrastructure metrics is useless without knowing if it's actually affecting end-users and in which use-cases.
