Abstract: A method of selectively obtaining formatted dump data from a remote software product (18) employs an open Manager-Agent concept, where the Agent (17) is represented by the remote software product (18) and the Manager is represented by the local customer/vendor management station (21). A dump object is defined; this object exists at the Agent (17) and is exposed to Manager (21) for modification, e.g., specification of a value. Modification of the dump object by the Manager (21) will cause the Agent (17) to selectively create/store a formatted storage dump for one or more of software products components (18). The Manager (21) retrieves the formatted dump data from the Agent (17) using a standard/open file transfer mechanism; since the dump data is formatted at the Agent (17) (rather than by the receiver, i.e., manager (21)) 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 (21) and Agent (17) 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 (17), 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.

Abstract: A new system and method allows a Manager in a Simple Network Management Protocol (SNMP) environment to gather updates from its Agents. The system and method comprise the unique provision of an index which is used in each of the Agent's tables for indicating the various revisions thereof. The index lexicographically increases with each revision to the table. The Manager maintains a record of the index of the data which it has received from its Agents, requesting only that data having a lexicographically larger indexing. Further, the index is used in related tables so that the tables will be kept in "sync" in that the Manager will know whether it has the latest updates so that an accurate picture may be portrayed.

Abstract: A method of data retrieval reduces the number of Instrumentation message flows in a Simple Network Management Protocol (SNMP) device (38). The method uses "look-ahead" algorithms whereby data items which have not yet been requested by the Agent (36) (but are expected to be) are retrieved from Instrumentation (42). The method comprises the step of retrieving from the Instrumentation an entire row of data from an SNMP table whenever a GetRequest or GetNextRequest Protocol Data Unit (PDU) is issued by the Manager (22) to the Agent. A SubAgent (40) saves this row in anticipation of a subsequent request for another column in this same row thereby eliminating the need for further Instrumentation message flows for further data retrieval from this row. Whenever a new GetRequest is issued by the Manager, a new set of data is retrieved from the Instrumentation. The method further comprises the step of retrieving the next subsequent data item in response to a GetNextRequest against the last row in a given column thereby eliminating the need for a second message exchange at an "end of column" condition.
