Because using the Administration Server takes computing resources, the command-line
interface and the Admin Console are the most costly monitoring methods.
For more information on these monitoring methods, see the following sections:

About Statistics
You can monitor many performance statistics through the Admin Console user interface,
through the command-line interface, through the stats-xml URI, and through perfdump.For
all these monitoring methods, the server uses statistics it collects. None of these monitoring
methods will work if statistics are not collected.
The statistics give you information at the conguration level, the server instance level, or the
virtual server level. The statistics are broken up into functional areas.
For the conguration, statistics are available in the following areas:
■
Requests
■
Errors
■
Response Time
For the server instance, statistics are available in the following areas:
■
Requests
■
Errors
■
Response Time
■

■
Java Virtual Machine (JVM

■
