Abstract
Abstract A distributed computer system service monitor provides information to a user regarding the status of services available on the computer system. The computer system includes plural host computers which act as servers and clients in connection with the services. The computer system is logically segregated into functional entities and sub-entities which define service regions and system layers. At least one host computer serves as the service monitor and includes a discovery function for passing a set of queries to other host computers and for using the responses (i) to identify functional entities and sub-entities served by each host computer and (ii) to determine whether each host computer acts as a server or a client or both and (iii) to determine the service or services performed or consumed by each host computer. The service monitor constructs a database which stores service information for each functional entity. The service information includes at least a list of host computers within the functional entity; services available in the functional entity; and whether each host computer acts as a server or a client for each service. The service monitor periodically interrogates each host computer in the functional entity with a set of queries; records responses thereto and employs the responses to determine if a change in status of any of the services has occurred. If a change in status is determined, the change is indicated to the user. In addition, status changes are calculated for further system layers of functionality so as to determine the effect thereon of the status change.

Claim 3
Dependent Claim
27 words
The distributed computer system service monitor as recited in claim 1, wherein said discovery means transmits an identical first script of queries to each said host computer.
Claim 4
Dependent Claim
47 words
The distributed computer system service monitor as recited in claim 1, wherein said monitor means queries each said host computer, respectively, with a second script of queries that has been edited from said first script of queries, in accord with responses from each said host computer, respectively.
Claim 5
Dependent Claim
37 words
The distributed computer system service monitor as recited in claim 1, wherein said monitor means responds to a change in status, by displaying a screen which indicates by a display change, that a service status has changed.
Claim 6
Dependent Claim
73 words
The distributed computer system service monitor as recited in claim 1, wherein said monitor means responds to a change in status by calculating, for each of plural layers of service functionality, the effect of said change in status thereon and assigning to each screen which is used to display a layer of service functionality, a display change which provides a user with an indication of an effect thereon of said change in status.
