Every operations team has some way of monitoring their production environments.They might have OpenNMS, or one of the alternatives such as Nagios orHP’s Operations Manager. Perhaps they have created their own custom monitoringsystem. Whichever system they use, they will want your application to hookinto it so that they know the moment any error condition occurs, and where tolook for more details to determine what has gone wrong.

It is important to find out, right at the beginning of the project, how theoperations team expects to monitor your application, and make it part of yourrelease plan. What do they want to monitor? Where are they expecting your logsto be? What hooks should your application use to notify operations staff ofmalfunctions?
