Day 10 - Common Event Infrastructure

The Common Event Infrastucture can be configured in every possible way you can think of. You can configure processes, selectors, human tasks and everything else within WPS to send CEI events. Hence CEI can be used for auditing, notification, correlation, and deliver key performance indicators (KPI). CEI uses something called a WBI Session which is basically a context in which WBI Components execute.

It's very easy to generate lots and lots of data when enabling CEI both due to the amount of events that any reasonably sized and the fact that the entire BO may be logged on each event. As with ND and clustering there's a lot of things to configure in the WAS administration console, which of course makes it both very powerful and quite hard to get a grip on.

The setup of CEI must be thought through carefully before configuration. There is a huge risk that too much logging events will mess up the system performance. When used with care, CEI can become a powerful tool for information auditing.
