Getting Familiar with the Server Information Tab

The Server Information tab is just an information tab; you cannot modify the content nor the performance or behavior of your application or JVM from this tab. The tab contains a description table that lists the important server categories and identifies the values to which those categories are set. Table: Server Information Categories describes the categories.

Server Information Categories

Category Description

Connection

This identifies the application to which the JVM instance is connected. This connection will also appear in the JVM Browser.

Operating System

The operating system on which the application is running; for example, Windows 7.6.1.

OS Architecture

The operating system architecture; for example, x86 or SPARC.

Number of Processors

The number of CPUs available to the application.

Total Physical Memory

The total amount of physical memory on the computer.

PID

The monitored application's process identifier.

VM Version

The JVM name and version number.

VM Vendor

The name of the JVM vendor.

Start Time

The time at which the application run began.

Class Path

The Java application's class path; for example, C:\Program Files (x86)\Java\jdk1.7.0_04\missioncontrol\mc.jar.

VM Arguments

The virtual machine arguments used at startup; for example, -verbose:gc -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=7091

Application Arguments

The arguments specific to the applcation you are running; for example, com.jrockit.mc.rcp.start.MCMain.

Library Path

The path the JVM uses to find native libraries; for example, D:\java\jdk1.7.0_04\bin;C:\Windows\Sun\Java\bin

Boot Class Path

The JVM's boot class path; for example, D:\java\jdk1.7.0_04\jre\lib\resources.jar;D:\java\jdk1.7.0_04\jre\lib\rt.jar;D:\java\jdk1.7.0_04\jre\lib\sunrsasign.jar;D:\java\jdk1.7.0_04\jre\lib\jsse.jar;D:\java\jdk1.7.0_04\jre\lib\jce.jar;D:\java\jdk1.7.0_04\jre\lib\charsets.jar;D:\java\jdk1.7.0_04\jre\lib\jfr.jar;D:\java\jdk1.7.0_04\jre\classes

Current Heap Size

The amount of heap in use at the current time.

Committed Heap Size

The amount of heap committed to the application.

Maximum Heap Size

The maximum amount of heap available, as set by the command-line option -Xmx.
