Table of Contents
This chapter describes the Real-Time Analysis screen.
Real-Time Analysis screen provides detailed information needed for real-time monitoring of servers and WASs that are registered in SysMaster. The main function of Real-Time Analysis screen is to provide detailed information. When failure is detected during normal monitoring activity from the dashboard, Real-Time Analysis screen can be used to analyze the status of a single container.
Real-Time Analysis can be accessed from [WAS] > [Real-Time Analysis].
Real-Time Analysis Menu consists of the following two items.
-
Working List
A single container can be selected from the Working List to analyze its status in real-time. For more information, refer to "1.4. Working List".
-
Monitoring / Analysis
Data is displayed in charts and using summary tables by business and instance for each of the following sub menus.
Menu Item Description [Service(Active)] Check real-time data for Service, SQL, exception, and external transactions. [Snapshot] Check real-time data for threads, class loaders, collection objects, files, sockets, sessions, and environment variables. [Event] Check current day's event statuses and list of events.
Service(Active) provides information related to the currently running services such as EJBs, Servlets, etc.
Service(Active) can be accessed from [WAS] > [Real-Time Analysis] > [Service] and consists of the following tabs.
-
[Top N]
-
[Service]
-
[SQL]
-
[Exception]
-
