Configure Ports

About this task

Command Central uses the ports specified in the OSGi component to monitor Infrastructure Data Collector.

To configure the ports for the Infrastructure Data Collector OSGi component

In Connection Basics, configure the fields for the corresponding port type.

The following table describes the configurations for HTTP and HTTPS ports.

Field	Description
Enabled	Whether the port is enabled.
Port Number	The port number that you want to use. Type a number that is not already in use.
Alias	The port name that you want to use. Use an alias that is unique for the instance or component and can be included in a user-friendly URL. Use nly ASCII characters, numbers, underscore (_), dot (.), and a hyphen (-).
Keep Alive Timeout	When to close the connection if the server has not received a request from the client within this timeout value (in milliseconds); or when to close the connection if the client has explicitly placed a close request with the server.
Spare Threads Min	The starting number of request processing spare threads.
Redirect Port	The port to use when redirecting SSL connection requests.
Spare Threads Max	The maximum number of request processing spare threads.
Accept Count	The maximum number of simultaneous connection requests allowed in the connection queue.
Connection Timeout	The connection timeout (in milliseconds). This attribute is not set by default on HTTPS ports.
HTTP Header Size Max	The maximum incoming URL length in characters.
Upload Timeout Disable	Indicates if using a longer connection timeout is allowed when waiting for the servlet container to update.
Lookups Enable	Indicates if DNS lookups are allowed to get the actual host name of a remote client.

The following table describes the configurations for JMX and SSH ports.

Field	Description
Enabled	Whether the port is enabled.
Port Number	The port number that you want to use. Type a number that is not already in use. For JMX, select the port for monitoring, managing, and implementing the Java process. For SSH, select the port for remote shell services or execution processes.
Alias	The port name that you want to use. Use an alias that is unique for the instance or component and can be included in a user-friendly URL. Use nly ASCII characters, numbers, underscore (_), dot (.), and a hyphen (-).
JAAS Realm	Specifies the realm name that authenticates the Java Authentication and Authorization (JAAS) service.

The following table describes the configurations for JDWP port.

Field	Description
Port Number	The port number that you want to use. Type a number that is not already in use.
Alias	The port name that you want to use. Use an alias that is unique for the instance or component and can be included in a user-friendly URL. Use nly ASCII characters, numbers, underscore (_), dot (.), and a hyphen (-).
Suspend	Suspends the runtime until debugger connects.

Note: The JDWP port is only used when the profile is started in debug mode.

In Thread Pool Configuration, for HTTP and HTTPS ports, complete the fields that are described in the following table.

Field	Description
Enabled	Whether the listener uses this pool exclusively for dispatching requests. The existing thread pool is a global thread pool. If there is a very high load on this resource, there may be a delay until the global thread pool can process the request. When you enable the private threat pool option, the requests that come into this port do not compete with other server functions for threads. When you view the port details, the server reports the total number of private thread pool threads currently in use for the port.
Threadpool Min	The minimum number of threads for this private thread pool. The default value is 1.
Threadpool Max	The maximum number of threads for this private thread pool. The default value is 5.
Threadpool Priority	The Java thread priority. The default value is 5. Important: Use this setting with extreme care because it affects server performance and throughput.
