5.5 Runtime monitoring In today's market, there are probably hundreds of monitoring tools, so finding the right tool for your environment is a huge challenge even before you think about "how to monitor". So, choosing the right monitoring tool is definitely the first step in the process. However, this topic is out of the scope of this Redpaper, as it involves many man hours and depends on each company's corporate policies in choosing software. WebSphere monitoring involves delivering comprehensive fault management and proactive alert notifications, checking for impending problems, triggering appropriate actions, and gathering performance data for planning, analysis, and reporting. There are lot of third-party tools available for monitoring WebSphere Portal and also some IBM tools, such as IBM Tivoli Composite Application Management (ITCAM) and PV(Performance Viewer). Important: Note that we are not discussing the other important components in the WebSphere Portal infrastructure, such as the network, systems, databases, and so on. We only discuss the WebSphere Portal related metrics that need to be monitored. 5.5.1 What to monitor It is very important to first understand what exactly needs to be monitored in the WebSphere Portal infrastructure. For a highly available (24X7) environment, we recommend monitoring the following: JVM memory usage Server Response time CPU utilization Metrics of all Web applications User sessions and details Dynacache Enterprise JavaBeans (EJBs) Thread pools Java Database Connectivity (JDBC) Pools Custom Application MBeans (JMX™) attributes 5.5.2 Useful resources More information about monitoring methodologies can be found at: http://www.ibm.com/developerworks/websphere/library/techarticles/0608_hesmer/0608_ hesmer.html 168 IBM WebSphere Portal V6 Self Help Guide
