Java Server Details Test

This test reports the performance statistics pertaining to the Java Virtual Machine (JVM) running on an Orion server.

Target of the test : An Orion server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the Orion server being monitored.

Configurable parameters for the test
Parameter	Description
Test Period	How often should the test be executed.
Host	The host on which the Orion/Tomcat server is running.
Port	The port on which the specified Orion/Tomcat server is listening for HTTP requests.
EGURI	The JavaServerTest makes use of a file named EgPerfTest.jsp to generate measures. By default, this file is located in the <EG_INSTALL_DIR>/lib directory. To execute the JavaServerTest, move this file to one of the application directories of the Orion server. On Unix, you can execute the script /opt/egurkha/bin/setup_jserver to do this. While configuring the JavaServerTest, specify the location of the application directory where the EgPerfTest.jsp file resides, in the EGURI text box, in the following format: http://<Ipaddress:portNo/directory name>. For example, assume that the EgPerfTest.jsp is available in the JavaTest directory of the host 192.168.10.57:7077. Therefore, EGURI would be: http://192.168.10.57:7077/JavaTest.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Active threads	Indicates the number of active threads in the JVM.	Number	A high value for this measure is indicative of a high load on the JVM.
Total memory usage	Indicates the total memory available in the JVM.	MB	A high value indicates a high processing capability of the JVM. Watch for increasing memory usage over time, which could indicate a memory leak in one or more applications hosted on the application server.
Free memory	Indicates the unused memory in the JVM.	MB	A very low value of free memory is an indication of high memory utilization on the JVM.
