A method and apparatus for integrating event monitoring and management information from a plurality of different event monitoring and management systems are provided. With the method and apparatus, an event management system (EMS) portal is provided which performs the operations for integrating the event information from a plurality of different event management systems in a network. A human user, such as a system administrator, may send a request for event information to the EMS portal. The request may include selections of event management systems, event management tables, and/or fields in the event management tables that are of interest to the user. The EMS portal then uses database clients to query the databases for selected event management systems on the network. The queries request the event information corresponding to the selections in the request submitted by the user to the EMS portal. The event information is then sent to the EMS portal clients which store the event information in a portal database. The EMS portal then generates one or more event information reports and transmits them to the user.

Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     The present invention is directed to an improved data processing system and, in particular, an improved mechanism for event monitoring. More specifically, the present invention provides a mechanism through which event monitoring in a plurality of different event monitoring systems may be integrated. 
     2. Description of Related Art 
     An event management system is software that monitors servers, workstations and network devices for routine and non-routine events. For example, routine events such as log-ons help determine network usage, while unsuccessful log-ons are warnings that hackers may be at work or that the network access system is failing. Event managers provide realtime information for immediate use and log events for summary reporting used to analyze network performance. 
     An event management system is typically made up of client agents that reside in the remote devices, a central component for gathering the events, an event database and a reporting system to deliver the results. A human user, such as a system administrator, may make use of the reports provided by the reporting system to determine where possible repair or correction of the operation of the network may be required. 
     As networks become larger, more often the network may make use of event management software that is supplied by a plurality of different vendors. For example, a company may have Tivoli Enterprises Console monitoring events in one section of its network and may have another event management system, such as Unicenter from Computer Associates Incorporated, handling events in another area of the network. Thus, a system administrator must himself/herself make separate queries to the event database and reporting systems of each event management system in order to obtain an indication of where there are trouble spots in each area of the network. It is easy to see that this problem becomes cumbersome in large networks in which there are numerous different event management systems in use. 
     Thus, it would be beneficial to have a method and apparatus for integrating different event management systems such that a single reporting system may be used to report events from each of the event management systems. 
     SUMMARY OF THE INVENTION 
     The present invention provides a method and apparatus for integrating event monitoring and management information from a plurality of different event monitoring and management systems. With the present invention, an event management system (EMS) portal is provided which performs the operations for integrating the event information from a plurality of different event management systems in a network. A human user, such as a system administrator, may send a request for event information to the EMS portal. The request may include selections of event management systems, event management tables, and/or fields in the event management tables that are of interest to the user. 
     The EMS portal then uses database clients to query the databases for selected event management systems on the network. The queries request the event information corresponding to the selections in the request submitted by the user to the EMS portal. The event information is then sent to the EMS portal clients which store the event information in a portal database. The EMS portal then generates one or more event information reports and transmits them to the user. 
     These and other features and advantages of the present invention will be described in, or will become apparent to those of ordinary skill in the art in view of, the following detailed description of the preferred embodiments.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     FIG. 1 is an exemplary diagram of a distributed data processing system according to a known event management system. As shown in FIG. 1, a plurality of network devices  130 ,  140  and  150  are provided, each having a managed device  135 ,  145  and  155  associated with it. The managed devices  135 ,  145  and  155  may be, for example, the network devices themselves, components of the network devices, applications and software running on these devices, and the like. These managed devices  135 ,  145  and  155  have client agents associated with them that allow the event management system  110  to manage events occurring on these managed devices. 
     The event management system  110  monitors the managed devices  135 ,  145  and  155  for both routine and non-routine events. Records, or event logs, of these events are stored in the associated database  115  for later use in reporting the events to a system administrator. 
     An event record is generated by the event management system  110  querying one or more tables in the database  115 . The event management system  110  receives event messages from the client agents associated with the managed devices  135 ,  145 ,  155 , and these events have a fixed number of attributes. For example, an event may be comprised of the following attributes: date, host name, time, message, source, origin, status, etc. Depending on the particular event, certain ones of these attributes will have associated values representing the event that occurred. 
     In other words, an event is a combination of fields stored in one or more tables in the database  115 . The event management system  110  simply populates the appropriate fields in one or more tables in the database  115  when an event message is received from a client agent. 
     A system administrator may obtain access to the event logs stored in the database  115  through the administrator console  120 . A display of the event log may be obtained by requesting a report from the event management system  110  or may be provided, in some cases, when certain events occur. When the administrator console  120  queries the event management system  110  for an event report, the event management system  110  retrieves the appropriate information from the various tables in the database  115  to thereby generate a report for the administrator console  120 . 
     It is important to note that, with this known system, only a single event management system  110  is provided. In other words, a single vendor supplies the managed devices  135 ,  145 , and  155  along with the event management system  110  such that there is a close coupling between the managed devices  135 ,  145 , and  155  and the event management system  110 . 
     In other networks, there may be a plurality of event management systems  110  managing different managed devices. In such a network, the system administrator is either required to access the event management system  110  from different administrator consoles  120  or access each event management system  110  individually, one at a time, to obtain information regarding events requiring the system administrator&#39;s attention. 
     The present invention alleviates the drawbacks of this known system by providing an event management system portal that integrates information obtained from a plurality of different event management systems. In this way, the system administrator may be provided with an integrated interface through which reports of the events encountered by the various event management systems may be accessed without having the system administrator individually access each event management system directly himself/herself. 
     FIG. 2 is an exemplary diagram illustrating a distributed data processing system according to the present invention. As shown in FIG. 2, a plurality of event management systems  210 ,  220  and  230  are used to manage and monitor the managed systems  212 - 216 ,  222 - 226  and  232 - 236  of the distributed data processing system. Each event management system  210 ,  220  and  230  also has an associated event database  211 ,  221 ,  231  which may be accessed by administrator consoles  218 ,  228  and  238 . These elements are similar to known systems in which a plurality of event management systems are used to monitor and manage events from managed devices. 
     The present invention, however, provides an event management system (EMS) portal  250  that provides the functionality of obtaining event information from each of the event management systems databases  211 ,  221  and  231 , and integrating this event information into a single interface for use with a client device  260 . In addition, the EMS portal  250  further includes an associated database  255  in which the integrated event information may be stored as records or logs for later use. 
     The EMS portal  250  includes a client for each of the databases that exist in the event management systems that need to be queried. For example, a distributed data processing system may include a Tivoli Enterprise Console event management system and a Computer Associates Incorporated Unicenter event management system. In such a case, the EMS portal  250  would have both a DB2 client for communicating with the database associated with the Tivoli Enterprise Console event management system and a Oracle client for communicating with the HP event management system database. 
     The EMS portal  250  further includes an interface for communicating with the client device  260 . In a preferred embodiment, the system administrator may access the EMS portal  250  by way of the client device  260 . Appropriate security measures may be employed on the communication between the client device  260  and the EMS portal  250  in order to protect the distributed data processing system from third party attacks and/or hacking into the system. 
     The EMS portal  250  further includes one or more portal applications for performing the functions of the present invention. The one or more portal applications include applications that query the individual event management system databases  211 ,  221  and  231  using their respective clients resident in the EMS portal  250 . The one or more portal applications further include applications that present the results of such queries using a single interface with the client device  260 . 
     In a preferred embodiment of the present invention, the EMS portal  250  is resident on a server device with appropriate software applications for providing the database clients, webserver interface application, and portal applications of the present invention. The client device  260  preferably communicates with the EMS portal  250  server via a network, such as a local area network, wide area network, the Internet, or the like. The client device  260  may make use of a web browser application or other appropriate interface for communicating with the EMS portal  250  server. 
     Security protocols may be used for authentication of queries from the client device  260  to the EMS portal  250  server. For example, the client device  260  may communicate with the EMS portal  250  server using the Secure Socket Layer (SSL)/Hypertext Transport Protocol (HTTP), as is well known in the art. Other security measures, such as the use of digital signatures, digital certificates, encryption, and the like, may also be used to guard against unauthorized access to the event management system databases and event information. 
     In operation, the EMS portal  250  receives a query from the client device  260  for event log information. The query may include, for example, an indication of which event management systems from which event log information is requested and which tables, and fields of the tables, are of interest to the system administrator that initiated the request. 
     The designation of which tables and fields are of interest may be done globally such that the selection of tables and fields applies to each event management system or may be done for each individual event management system such that certain fields of certain tables are retrieve for a first event management system and other fields of the same or different tables are retrieved for a second event management system. This designation of event management systems, tables, and fields may be stored as a preference that may be retrieved at a later time in order to avoid having the administrator repeatedly enter the same request information. 
     The EMS portal  250  receives the query and instructs the appropriate database clients to transmit queries to the event management system databases  211 ,  221 , and  231 . The retrieved information is then stored in the EMS portal database  255 . The retrieved information is then formatted into one or more appropriate reports by the EMS portal  250  into an appropriate format based on the selection of fields included in the event information request. The reports are then transmitted to the client device  260  for use by the administrator. 
     FIG. 3 is a block diagram illustrating the primary operational components of the EMS portal according to the present invention. The components shown in FIG. 3 may be implemented as hardware, software, or any combination of hardware and software elements. In a preferred embodiment, the components are implemented as software instructions executed on one or more processors. 
     As shown in FIG. 3, the EMS portal includes a controller  310 , a network interface  320 , a plurality of EMS database clients  330 - 340 , a database interface  350 , and a report generation engine  360 . These elements are coupled to one another via the control/data signal bus  370 . Although a bus architecture is shown in FIG. 3, the present invention is not limited to such an implementation. Rather, any mechanism for facilitating the communication of control/data messages between the elements  310 - 360  may be used without departing from the spirit and scope of the present invention. 
     The controller  310  controls the overall operation of the EMS portal and orchestrates the operation of the other elements  320 - 360 . The controller  310  receives requests for event information from client devices and supplies event information reports to these client devices via the network interface  320 . In addition, in this exemplary embodiment, the EMS database clients  330  and  340  may communicate with the EMS databases via the network interface  320  or other communication interface (not shown). 
     The database interface  350  is used to store and retrieve event information stored in the portal database. This event information is received from the EMS databases in response to queries for the event information being sent from the EMS database clients  330  and  340 . The EMS database clients  330  and  340  send queries to the EMS databases based on instructions received from the controller  310 . The controller  310  sends such instructions to the EMS database clients  330  and  340  in response to the receipt of an event information request from a client device. 
     FIG. 4 is an exemplary diagram illustrating an event information report as it is displayed on a client device. As shown in FIG. 4, the event information report may be comprised of a plurality of interfaces  410 - 430  each providing the event information for one or more of the EMS databases queried by the EMS portal. 
     In the particular exemplary embodiment shown in FIG. 4, the interfaces  410 - 430  are separate browser instances in a windowed environment. This allows a human system administrator to easily switch between interfaces in a manner generally known in the art. In other exemplary embodiments, these interfaces may be provided as a series of web pages, as spreadsheets, as text documents, or the like. 
     While the specific example shown in FIG. 4 illustrates the event information being provided to a system administrator via a browser application on the client device, the present invention is not limited to such. Rather, any mechanism for transmitting event information requests and displaying the resulting event information may be used without departing from the spirit and scope of the present invention. For example, the event information reports may be provided in an electronic mail format and may be displayed via an electronic mail program. 
     Alternatively, as touched upon above, the event information reports may be store sent as files, either downloaded to the client devices or sent as attachments to electronic mail messages, formatted in a known format for use with existing applications. For example, the event information reports may be stored as Microsoft Excel™ spreadsheet files, Lotus WordPro™ document files, or the like. 
     Although FIG. 4 shows a separate interface for each EMS database, the invention is not limited to such. Rather, any mechanism for displaying the event information may be used without departing from the spirit and scope of the present invention. For example, the results of the queries to the EMS databases may be combined into a single interface that is provided to the system administrator via the client device in any of the ways described previously. 
     In short, any mechanism may be used for sending requests for event information to the EMS portal and displaying event information reports received from the EMS portal. The key difference with these mechanisms and those used in the known art is that the system administrator is communicating with an EMS portal to which a single request may be sent and event information may be received from a plurality of different EMS databases. 
     FIG. 5 is a flowchart outlining an exemplary operation of the present invention. As shown in FIG. 5, the operation starts with receipt of a request for event information from a client device (step  510 ). The database clients are then used to query the EMS databases for the event information requested in the request received from the client device (step  520 ). The requested event information is then received from the EMS databases (step  530 ) and stored in the portal database (step  540 ). One or more event information reports are then generated based on the event information received from the EMS databases (step  550 ). The one or more reports are then transmitted to the requesting client device (step  560 ) and the operation ends. 
     Thus, the present invention provides an EMS portal through which a system administrator may query a plurality of different types of EMS databases with a single request for event information. This greatly reduces the burden on the system administrator and provides a mechanism by which event information may be retrieved from a plurality of different sources quickly and easily. 
     It is important to note that while the present invention has been described in the context of a fully functioning data processing system, those of ordinary skill in the art will appreciate that the processes of the present invention are capable of being distributed in the form of a computer readable medium of instructions and a variety of forms and that the present invention applies equally regardless of the particular type of signal bearing media actually used to carry out the distribution. Examples of computer readable media include recordable-type media, such as a floppy disk, a hard disk drive, a RAM, CD-ROMs, DVD-ROMs, and transmission-type media, such as digital and analog communications links, wired or wireless communications links using transmission forms, such as, for example, radio frequency and light wave transmissions. The computer readable media may take the form of coded formats that are decoded for actual use in a particular data processing system. 
     The description of the present invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention, the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
