Synthetic Monitoring   is an active approach to testing a website or web service by simulating visitor requests to test for availability, performance, and function. Synthetic Monitoring is a generic term applied to many different types of website and server monitoring solutions. Synthetic monitors operate like bots that connect to websites, web services, APIs, and servers to verify availability, function, and performance using a network of   checkpoints   external to the website’s own servers from various parts of the network or world. Why to use Synthetic Monitoring? Any company or brand that provides content or services through a network or the Internet needs Synthetic Monitoring to protect productivity, revenue, and reputation. When availability and performance are mission critical, a brand can’t wait for end-users to notify them of a problem. By the time end users begin to complain, it is too late. The brand has taken on damage due to the problems, and until the problem is resolved

What is Synthetic Monitoring? Organizations depend on fully functioning IT systems and processes to attract customers, deliver services and manage internal operations. The operation of these systems and processes directly impacts the business and reputation of each organization. Ensuring that all IT systems and processes are fully functional 24×7 is a key component of any organization’s IT performance management strategy. This is where synthetic monitoring comes in. Synthetic or directed monitoring is a method to monitor your applications by simulating users – directing the path taken through the application. This directed monitoring provides information as to the uptime and performance of your critical business transactions, and most common paths in the application. The simple reality is that there is no easy way to combine the accessibility, coherence, and manageability offered by a centralized system with the sharing, growth, cost, and autonomy advantages of a distributed system.

In such type of scenarios you can easily consume performance statistics from your WebSphere instance. The way is to establish a JMX connection to the JVM and gather the metrics. However remote JMX connections are not firewall friendly as they require a non standard port for communication.This non standard port has also to be defined in the WebSphere configuration. WebSphere provides a small and easy to install servlet applications that delivers performance data over http in a xml format. The application is called PerfServletApp.ear, Performance Servlet or PerfServlet. The installation is straight forward. Navigate to Applications > Application types > WebSphere enterprise applications > Install and deploy the PerfServletApp.ear located in <WebSphere-Install-Root>/installableApps/PerfServletApp.ear After deployment the Performance Servlet is reachable under the URL Filtering the results The performance servlet provides a basic filter functionality for the xml results.
