Abstract

A method for accumulating fault condition data from a hierarchical system is presented comprising monitoring an operation of a component with a computing node that includes a processor and a memory. The memory contains a configuration file comprising failure modes (FM), symptoms, tests that identify the symptoms and a corrective action for the symptom. The method further comprises populating at least one of the processor and the memory of the computing node with one or more standardized executable application modules (SEAM) and a workflow service. The one or more SEAMS is configured to create a fault condition record by collecting all FMs that manifest the symptom. For all FMs collected, a list of unique symptoms is produced. Further all tests that can identify the listed unique symptoms and all of the corrective actions associated with the FMs that manifest the symptom are determined from the memory device.

First claim

What is claimed is:

1. A condition based method for accumulating supplemental fault condition data for a new fault condition record from a remote nodes in a hierarchical monitoring system, comprising:
monitoring an operation of a component of a complex system with a computing node that includes a processor and a memory device, the memory device containing, a configuration file, the configuration file comprising failure modes (FM), symptoms manifested by the FMs, and a data collection specification for each failure mode; and
populating at least one of the processor and the memory of the computing node with one or more standardized executable application modules (SEAM) and a workflow service, wherein the one or more SEAMS are unable to communicate directly with each other; wherein further one of the one or more SEAMS is configured to retrieve supplemental data associated with the new fault condition record by:
determining all FMs that manifest the symptom of the new fault condition from the memory device,
examining a data collection specification associated with each of the FMs determined to identify each determined FM that requires supplemental fault condition data from the remote node,
creating a data collection request message to the remote node,
receiving supplemental data requested in the data collection request message from the remote node, and
incorporating the supplemental data into the fault condition record.

2. The method of claim 1 , wherein the one or more SEAMs includes an Allocate SEAM and a Coordinate SEAM.

3. The method of claim 2 , wherein the Coordinate SEAM is configured to communicate the data collection request message to the remote computing nodes.

4. The method of claim 3 , wherein the data collection specification identifies the supplemental data to be collected, the remote node that that should collect the data, a collection period and instructions to process the data collected.
