Overview
up.time provides the capability to monitor the performance and health of Java applications that are running on a WebSphere server. Use up.time to identify correlations between system performance and the Java application server, track end-user and database response times, and monitor a range of WebSphere server statistics.
The following diagram provides a high-level illustration of how up.time monitors a WebSphere Application Server:
...
Deploying the WebSphere Servlet
Before up.time can begin collecting information from a WebSphere server, you must first deploy the performance servlet in the WebSphere directory that contains your web application. The WebSphere performance servlet uses WebSphere's Performance Monitor Interface (PMI) infrastructure to retrieve performance information from a WebSphere Application Server.

- On the WebSphere server, locate the following file:
install_root/perfServletApp.earWhere
install_rootis the directory under which WebSphere is installed. - Copy the file
perfServletApp.earto the directory in which your Web application is installed. For example:install_root/installedApps/<cell_name>/DefaultApplication.ear/DefaultApplication.war/WEB-INF/classesWhere:
install_rootis the directory under which WebSphere is installed.<cell_name>is the name of the WebSphere node under which your Web application is installed.

Configuring up.time to monitor WebSphere
The up.time WebSphere monitor collects data that you can use to generate a report that will provide a historical view of problems that occur on a WebSphere server. The monitor enables you to collect data so that you can:

You can also use the up.time HTTP and database monitors to collect information on the status of applications that are running on a WebSphere server. See the Database Monitors and Network Service Monitors chapters in the up.time User Guide for more information.

Reports and Graphs
After up.time has collected a sufficient amount of information from a WebSphere server, you can use the WebSphere report to gain insight into the health and performance of a WebSphere Application Server. Reports can be configured to include any or all of the following metrics:
