    • Improved techniques for reporting events raised by entities running on computer networks are disclosed. The techniques provide an event distribution system that handles events generated by various software and other entities installed on a computer or communications network. The event distribution system is capable of handling large volumes of event traffic and can be installed and operated separately from other network management software components to provide thereby more robust operations in the case one or more components fail. In addition, the event distribution system can be scaled readily to handle greater volumes of network traffic. In one embodiment, an event distribution service is coupled with an event source. In addition, an event listener is provided on the computer network. When an event is generated from the event source and received by the event distribution system, the event distribution system processes and forwards the event, or a notification of the event, to an appropriate listener.
    • 披露了用于报告在计算机网络上运行的实体提出的事件的改进技术。 这些技术提供了处理由计算机或通信网络上安装的各种软件和其他实体产生的事件的事件分发系统。 事件分配系统能够处理大量事件流量,并且可以与其他网络管理软件组件分开安装和操作,从而在一个或多个组件出现故障的情况下提供更强大的操作。 此外,事件分配系统可以轻松扩展,以处理更大量的网络流量。 在一个实施例中,事件分发服务与事件源耦合。 另外,在计算机网络上提供事件侦听器。 当从事件源生成事件并由事件分发系统接收到事件时,事件分发系统将事件或事件的通知处理并转发给适当的侦听器。

    • A method for processing events generated by software and hardware entities installed on a computer network that avoids overload conditions at large event processing rates is provided. In one embodiment, the method includes the steps of providing a protocol translation facility that is configured to translate messages from a first network communications protocol to a second network communications protocol. The protocol translation facility is further configured to receive events transmitted by software and hardware entities on the network. The protocol translation facility forwards the events to a management information server. An event is received, and a determination is made whether an association between the protocol translation facility and the entity exists. The event is processed

    • An access control database defines access rights through the use of access control objects. The access control objects include group objects, each defining a group and a set of users who are members of the group, and rule objects. Some of the rule objects each specify a set of the group objects, a set of the management objects, and access rights by the users who are members of the groups defined by the specified set of the group objects to the specified set of management objects. A plurality of access control servers are used to process access requests. Each access control server controls access to a distinct subset of the management objects in accordance with the access rights specified in the access control database. At least one of the access control servers receives access requests from the users and distributes the received access requests among the access control servers for processing. A subset of the access requests specify operations to be performed on specified sets of the management objects. Each of these access requests is sent for processing to one or more of the access control servers in accordance with the management objects to which access is being requested. The access control servers responding to the access requests from the users by granting, denying and partially granting and denying the access requested in each access request in accordance with the access rights specified in the access control database.

    • An access control database defines access rights through the use of access control objects. The access control objects include group objects, each defining a group and a set of users who are members of the group, and rule objects. A first subset of the rule objects each specify a set of the group objects, a set of the management objects, and access rights by the users who are members of the groups defined by the specified set of the group objects to the specified set of management objects. The access control server responds to the access requests from the users by granting, denying and partially granting and denying the access requested in each access request in accordance with the access rights specified in the access control database. A second subset of the rule objects in the access control database each specify user access rights to event notifications generated by the specified set of management objects. An event registry is used for registering event notification requests by users, each event notification request specifying event notifications from specified sets of the management objects that are being requested. An event router receives event notifications generated by the management objects. It responds to each event notification by sending corresponding event notification messages to users who have registered a corresponding event notification request with the event registry and also have access rights to the received event notification in accordance with the access rights specified in the access control database.
