You can monitor these kinds of statistics, and more, with Java Management Extensions (JMX). Because the Java Virtual Machine has specific quirks with how memory is utilized (say, separating the memory space into partitions such as heap and non-heap space), just looking at the OS-level resource utilization is not generally adequate. Depending on how you configure, you may either monitor a local process or a Java process running on another system, via a graphical user interface tool such as JConsole (or VisualVM although I cannot get it run properly).
With JMX, you can even write some simple Java program to log selected statistical values periodically on a 24x7 basis and analyse them later offline.
You can refer to this document for an introduction of Java SE management and JMX technology:
- Java SE Monitoring and Management Guide
Or read the JMX specification if you wish to get more in-depth programming knowledge.

native2ascii
native2ascii(1) General Commands Manual native2ascii(1)
NAME
native2ascii - native to ASCII converter
SYNOPSIS
native2ascii [ options ]
[ inputfile [outputfile]]
DESCRIPTION
The Java compiler and other Java tools can only process files that contain Latin-1 or Unicode-encoded (udddd notation) characters.
native2ascii converts files that contain other character encoding into files containing Latin-1 or Unicode-encoded charaters.
If outputfile is omitted, standard output is used for output. In addition, if inputfile is omitted, standard input is used for input.
OPTIONS
The following options are supported:
-encoding encoding_name
Specifies the encoding name that is used by the conversion procedure. The default encoding is taken from system property file.encod-
ing. The encoding_name string must be one taken from the first column of the table of supported encodings in the Supported Encodings
document:
http://java.sun.com/j2se/1.5/docs/guide/intl/encoding.doc.html
-reverse
Performs the reverse operation: converts a file with Latin-1 or Unicode-encoded characters to one with native-encoded characters.
-Joption Pass option to the Java virtual machine, where option is one of the options described on the man page for the java applica-
tion launcher, java(1). For example, -J-Xms48m sets the startup memory to 48 megabytes. It is a common convention for -J to
pass options to the underlying virtual machine.
