Domains: Monitoring: Servers

Column Display     Related Tasks     Related Topics

Use this page to monitor the runtime status of servers that are part of the current WebLogic Server domain.

Column Display

You can show fewer or additional data points on this page by expanding Customize this table and modifying the Column Display list. Each data point displays in its own table column.

The following table lists all of the data points that you can display in columns on this page.

Name Description
Name of

The alphanumeric name for this server instance.

MBean Attribute:
ServerMBean.Name

Changes take effect after you redeploy the module or restart the server.

Machine

The WebLogic Server host computer (machine) on which this server is meant to run.

If you want to use a Node Manager to start this server, assign the server to a machine and configure the machine for the Node Manager.

You cannot change this value if a server instance is already running.

MBean Attribute:
ServerMBean.Machine

Changes take effect after you redeploy the module or restart the server.

State

The current life cycle state of this server.

For example, a server can be in a RUNNING state in which it can receive and process requests or in an ADMIN state in which it can receive only administrative requests.

MBean Attribute:
ServerRuntimeMBean.State

Listen Port

The default TCP port that this server uses to listen for regular (non-SSL) incoming connections.

If this port is disabled, the SSL port must be enabled. Additional ports can be configured using network channels. The cluster (multicast) port is configured separately.

MBean Attribute:
ServerMBean.ListenPort

Minimum value: 1

Maximum value: 65534

Listen Address

The IP address or DNS name this server uses to listen for incoming connections.

Servers can be reached through the following URL:
protocol://listen-address:listen-port

Any network channel that you configure for this server can override this listen address.

If a server's listen address is undefined, clients can reach the server through an IP address of the computer that hosts the server, a DNS name that resolves to the host, or the localhost string. The localhost string can be used only for requests from clients that running on the same computer as the server.

If you want to limit the valid addresses for a server instance, specify one of the following:

  • If you provide an IP address, clients can specify either the IP address or a DNS name that maps to the IP address. Clients that specify an IP address and attempt to connect through an SSL port must disable hostname verification.

  • If you provide a DNS name, clients can specify either the DNS name or the corresponding IP address.

Do not leave the listen address undefined on a Windows computer that uses multiple IP address (a multihomed computer). On such a computer, the server will bind to all available IP addresses.

Note:

To resolve a DNS name to an IP address, WebLogic Server must be able to contact an appropriate DNS server or obtain the IP address mapping locally. Therefore, if you specify a DNS name for the listen address, either leave a port open long enough for the WebLogic Server instance to connect to a DNS server and cache its mapping or specify the IP address mapping in a local file. If you specify an IP address for ListenAddress and then a client request specifies a DNS name, WebLogic Server will attempt to resolve the DNS name, but if it cannot access DNS name mapping, the request will fail.

MBean Attribute:
ServerMBean.ListenAddress

Changes take effect after you redeploy the module or restart the server.

Expected To Run

If this server expected to run if the domain is started.

Changes take effect after you redeploy the module or restart the server.

Resend Requests

Provides the number of state-delta messages that had to be resent because a receiving server in the cluster missed a message.

Returns the number of state-delta messages that had to be resent because a receiving server in the cluster missed a message.

MBean Attribute:
ClusterRuntimeMBean.ResendRequestsCount

Fragments Sent

Returns the total number of message fragments sent from this server into the cluster. This is applicable to both multicast and unicast message types.

MBean Attribute:
ClusterRuntimeMBean.FragmentsSentCount

Fragments Received

Provides the total number of messages received on this server from the cluster. This is applicable to both multcicast and unicast message types.

MBean Attribute:
ClusterRuntimeMBean.FragmentsReceivedCount

Multicast Messages Lost

Provides the total number of in-coming multicast messages that were lost according to this server.

MBean Attribute:
ClusterRuntimeMBean.MulticastMessagesLostCount

Foreign Fragments Dropped

Provides the number of fragments that originated in foreign domains or clusters which use the same multicast address.

Answer the number of fragments that originated in foreign domains/cluster that use the same multicast address.

MBean Attribute:
ClusterRuntimeMBean.ForeignFragmentsDroppedCount

Primary

Provides the number of object that the local server hosts as primaries.

Answer the number of object that the local server hosts as primaries.

MBean Attribute:
ClusterRuntimeMBean.PrimaryCount

Currently Open Sockets

The current number of sockets registered for socket muxing on this server.

MBean Attribute:
ServerRuntimeMBean.OpenSocketsCurrentCount

Total Sockets Opened

The total number of registrations for socket muxing on this sever.

MBean Attribute:
ServerRuntimeMBean.SocketsOpenedTotalCount

Heap Size Current

The current size (in bytes) of the JVM heap.

MBean Attribute:
JVMRuntimeMBean.HeapSizeCurrent

Heap Free Current

The current amount of memory (in bytes) that is available in the JVM heap.

MBean Attribute:
JVMRuntimeMBean.HeapFreeCurrent

OS Version

The version of the operating system on which the JVM is running.

MBean Attribute:
JVMRuntimeMBean.OSVersion

WebLogic Version

The version of this WebLogic Server instance (server).

MBean Attribute:
ServerRuntimeMBean.WeblogicVersion
