Abstract

A method of selectively obtaining formatted dump data from a remote software product employs an open Manager-Agent concept, where the Agent is represented by the remote software product and the Manager is represented by the local customer/vendor management station. A dump object is defined; this object exists at the Agent and is exposed to Manager for modification, e.g., specification of a value. Modification of the dump object by the Manager will cause the Agent to selectively create/store a formatted storage dump for one or more of software products components. The Manager retrieves the formatted dump data from the Agent using a standard/open file transfer mechanism; since the dump data is formatted at the Agent (rather than by the receiver, i.e., manager) the problem of transmitting large amounts of data across a network is minimized or eliminated. This method is product- and product-level independent; since the Manager and Agent interactions do not involve product-specific logic, it can be used to selectively obtain formatted dump data from any software product, and, since the formatting is done by the Agent, there is no problem in matching the level of the format routine to the product level. The Manager-Agent interactions are network management protocol independent, and may use a standard such as SNMP.

Claims

1. Apparatus for managing a network and executing by data processing equipment for dynamically creating and retrieving formatted dump data, said network being of the type having a plurality of nodes coupled by connecting links, having a given process operating on said network at one of said nodes, and having an agent operating on said network at each of said nodes separate from said process, comprising:

means for sending a first command from a manager at one of said nodes to one of said agents at a different one of said nodes to set a value in a dump object in said one of said agents, said value indicating that said agent is to execute a selected command among a plurality of commands;

means for processing said dump object having said value in said one of said agents by executing the selected command to dynamically generate said formatted dump data whereby said formatted dump data becomes part of said dump object;

means for sending a second command from said manager at said one of said nodes to said one of said agents to request that said formatted dump data be sent from said dump object of said agent to said manager; and

means for sending said formatted dump data from said agent to said manager.

2. Apparatus according to claim 1 wherein said means for generating is an operative part of said dump object.

3. Apparatus according to claim 2 wherein said means for sending a second command sends said second command to said dump object.

4. Apparatus according to claim 1 wherein said means for generating obtains data from said process.

5. Apparatus according to claim 1 wherein said means for sending employ a standard network management protocol manager.

6. A method for executing by data processing equipment for dynamically creating and retrieving formatted dump data in managing a network, said network being of the type having a plurality of nodes coupled by connecting links, having a given process operating on said network at one of said nodes, and having an agent operating on said network at each of said nodes separate from said process, comprising the steps of:

sending a first command from a manager at one of said nodes to one of said agents at a different one of said nodes to set a value in a dump object in said one of said agents, said value indicating that said agent is to execute a selected command among a plurality of commands;

processing said dump object having said value in said one of said agents by executing the selected command to dynamically generate said formatted dump data whereby said formatted dump data becomes part of said dump object;

sending a second command from said manager at said one of said nodes to said one of said agents to request that said formatted dump data be sent from said dump object of said agent to said manager; and

sending said formatted dump data from said agent to said manager.

7. A method according to claim 6 wherein the step of generating is performed by said dump object.

8. A method according to claim 7 wherein said step of sending a second command sends said second command to said dump object.

9. A method according to claim 8 wherein the step of generating obtains data from said process.

10. A method according to claim 9 wherein said steps of sending employ a standard network management protocol.
