To begin monitoring a server, it is necessary to first check the server you want to monitor is in the servers list. The list can be viewed by clicking Monitoring under the Server category after loging in to the administrative console using the default account and password: system/manager.

Introduction to the predefined graphs and views
Views Anchor predefinedview
A view is used to bundle related graphs together for more manageable use. For example, all graphs related to a specific server can be bundled together. Two predefined views, TomcatWebConnector View and TomcatWebSSLConnector View, are provided to monitor the statistics for the Tomcat Web Connector and the Tomcat Web SSL Connector being used respectively. The following table lists the predefined graphs that are bundled to these two predefined views. See graphs for description of each graph.
