From the top of the Tomcat forum
Java Ranch and Java-monitor teamed up to offer registered Java Ranch users a unique service: the easy road to Tomcat tuning.
What does Java-monitor do?
Always wondered how much heap memory you need for your Tomcat server? Would you like to know how big the thread pools on your server should be? Or the database connection pools?
Just deploy a single WAR file in your application server and Java-monitor will do the rest. We will make pretty graphs of your memory, garbage collector activity, thread pools and database pools. Using those it is trivially easy to tune them to the right sizes.
Java-monitor even sends out e-mail alerts if your application server goes off-line. That way you are the first to know when that happens. You can respond to outages before your customers start complaining or even notice.
Ready to Get Started?
Log into Java Ranch
Download the probe by clicking the "download probe" link.
Unzip the probe.
Install "java-monitor.war" in your Java application server.
Finally return to the Tomcat forum on the Big Moose Saloon to find your server telemetry.
To use this service there is no need to sign up, create accounts or remember yet another password. There is no need to change the code for your application server. Java-monitor does not instrument your JVM or application code. You don't even have to restart your server. Just drop in the WAR file and you are done.
How does it work?
The Java-monitor server collects the JVM telemetry for your application server. When you visit the Tomcat forum on the Big Moose Saloon, Java-monitor generates graphs for you.
