Abstract

A computer system used in monitoring another computer system provides both textual resolution information describing a likely solution for a problem encountered in the monitored computer system as well as component information that relates to the particular problem. The component information includes the various hardware, software and operating conditions found in the monitored computer system. The monitoring computer system determines if a condition of a predetermined severity exists in the monitored computer system according to diagnostic information provided from the monitored computer system. The diagnostic information is represented in the monitoring computer system as a hierarchical representation of the monitored computer system. The hierarchical representation provides present state information indicating the state of hardware and software components and operating conditions of the monitored computer system. The resolution information relating to the condition is retrieved from a resolution database and relevant component information is retrieved from the hierarchical representation of the computer system and presented to a support engineer to assist them in diagnosing the problem in the monitored computer system.

Claims

1. A method of monitoring a monitored computer system, comprising:

determining if a condition exists in current state information stored in a first storage location in a monitoring computer system, the current state information indicating a state of hardware and software components and operating conditions of the monitored computer system during a first time period, and wherein the current state information is represented as a tree structure, the tree structure including component information which represents the hardware and software components and operating conditions of the monitored computer system, the component information being extracted from diagnostic data provided by the monitored computer system;

retrieving component information related to the condition from the current state information when the condition is determined to exist;

presenting the component information on a display device;

providing a third storage location storing previous state information relating to the monitored computer system, the previous state information being represented as another tree structure, representing a state of the monitored computer system during a second time period, the second time period being different from the first time period; and

traversing the other tree structure to identify a missing component in the tree structure of the current state information and providing an indication of the missing component.

2. The method as recited in claim 1 further comprising:

retrieving resolution information relating to the condition from a second storage location in the monitoring computer system; and

presenting the resolution information with the component information on the display device.

3. The method as recited in claim 2 wherein textual resolution information is stored in a data base in the second storage location.

4. The method as recited in claim 1 further comprising retrieving second component information related to the condition from the previous state information.

5. The method as recited in claim 4 further comprising displaying the second component information on a display device.

6. The method as recited in claim 1 further comprising traversing the tree structure of the current state information according to the indication of the missing component in order to extract the component information related to the condition from the tree structure of the current state information.

7. The method as recited in claim 1 further comprising determining whether the condition is of a predetermined severity.
