The Enterprise Server v3 offers monitoring services for various objects.
Monitoring is the process of reviewing the statistics of a system to improve
performance or solve problems. The monitoring service can track and display operational statistics,
such as the number of requests per second, the average response time, and
the throughput. For more information on monitoring, see 
Chapter 8, Administering the Monitoring Service, in Sun GlassFish Enterprise Server v3 Administration Guide.
The JRuby Container installed on the Enterprise Server can be configured to be monitored. By default the monitoring services are disabled.
Monitoring can be configured for the container using the following asadmin CLI command:
configure-jruby-container --monitoring=true
The monitoring service can be enabled or disabled. Enable monitoring for GlassFish JRuby container with the following runtime command:
enable-monitoring --modules jruby-container=HIGH
The other possible values are OFF or LOW. Disable the monitoring for JRuby container with the following command:
disable-monitoring --modules jruby-container=OFF
JRuby statistics are available from asadmin CLI as well as from Administration Console.
To learn more about different types of JRuby statistics available from Enterprise Server,
see JRuby Statistics in Sun GlassFish Enterprise Server v3 Administration Guide.
