This document has the following sections:
The Resource Usage page allows you to dynamically view how your
Service (Web, Proxy, or Secure Web) resources are being used.
The Update Interval Field
The Update Interval field allows you to specify how often to update the
Resource Usage screen. You can choose to update the screen every 1-90
seconds. The default is 10 seconds.
The Next Update Field
The Next Update field is a clock that graphically shows how often
your Resource Usage screen is being dynamically updated.
The Memory Field
The entries in the Memory Field are shown in kilobytes (KB) and
displayed in two columns. These are:
- Memory - The total memory available to the system.
- Available - How much memory is actually available for the
service you are running.
The Handler Threads Field
The Handler Threads field shows the number of handler threads that can
be used to handle requests coming into your service. These are
displayed in two columns:
- Total - The total number of handler threads available to
your service.
- Available - The number of handler threads currently
available to field requests. The busier your service and the more
requests it must field per second, the lower the number of threads
that will be available.
For more information on how and where to set threads for your service,
see Service Tuning and
Tuning the Java Web Server.
The Requests Field
The Requests field shows you the number of connection requests your service
is receiving. These are displayed in two columns:
- Total - The total number of requests handled by your service.
- GETs - The number of requests handled by your service that are
specifically GET requests.
Note: If the number of GET requests handled by your service is not the
same as the total number of requests, your service has also received some POST
or PUT requests. For information about these requests you must look at the
output from the Access Log.
Buttons
To make changes to the Resource Usage page and have those settings take affect,
use the three buttons at the bottom of the screen. These are:
- Start/Restart View - Begins listing log entries. Any change
made to any of the Log Output fields does not take affect until you have
clicked on Start or Restart View.
- Stop View - Stops the display of log entries.
- Clear - Removes all the entries in the log output window and
leaves it blank.
