Java Application Monitor API Publisher's description
from Steve Souza
Java Application Monitor API is an easy-to-use performance tuning and scalability measuring API.
Java Application Monitor (JAMon) project is a free, simple, high performance, thread safe, Java API that allows developers to easily monitor production applications. JAMon can be used to determine application performance bottlenecks, user/application interactions, and application scalability.
JAMon gathers summary statistics such as hits, execution times (total, average, minimum, maximum, standard deviation), and simultaneous application requests. JAMon statistics are displayed in the clickable JAMon Report. Click JAMon report to see a live demo of JAMon.
JAMon was developed primarily for monitoring J2EE applications, however it can be used in any JDK 1.2 or higher environment. JAMon can be used in Servlets, JSP's, EJB's and Java Beans in various J2EE Application Servers (Sybase's EAServer, and BEA's WebLogic,??пїЅ), and can also be used in other programming environments that can call Java code (ColdFusion, PowerBuilder, BroadVision, ...).
Feel free to continue reading the user's guide or download JAMon and read the Java Docs.
Using JAMon is easy. Place JAMon.jar (90K) in your classpath, and surround the code that you wish to monitor with the JAMon API's start() and stop() methods. See the code sample below:
...Code Being Timed...
For example, to collect statistics for all JSP pages in a Web Application, a developer would place a call to the start() method at the top of every JSP, and a call to the stop() method at the bottom. With a few minutes work the developer will have statistics for all application pages. The statistics will include number of page hits, average page execution times, and the number of users simultaneously accessing each page. The statistics can be displayed as an HTML table by calling the getReport() method, or using JAMonAdmin.jsp.
JAMon requires no special administration accounts. Many monitoring tools require administrative accounts to install monit
What's New in This Release:В· This is a minor release that adds a few features that users requested after version 2.7. JAMon still requires JDK 1.4 or higher (with a couple exceptions).
В· If version 2.7 is working for you and you don't want the new features, then this is not a required upgrade.
System Requirements:No special requirements.
Program Release Status: Minor Update
Program Install Support: Install and Uninstall
