Fault-tolerant monitoring apparatus, method and system

A fault-tolerant monitoring method for monitoring physical performance properties of a plurality of networked computing elements, each element including a processing unit and an individual memory, the monitoring method comprising

• measuring the physical performance properties of computing elements using measurer apparatuses and storing local information representing the physical performance properties in the individual memory of the corresponding computing elements;
• and
• collecting remote information representing physical performance properties from the individual memory in a particular computing element using a collector apparatus and storing the remote physical performance information as replicate information in the individual memory of another computing element;
• wherein the remote physical performance information is collected using third party access.

A non-transitory computer-readable medium tangibly embodying a computer program, which when loaded onto a distributed memory computer system with a plurality of networked computing elements configures the distributed memory computer system to

• measure physical performance properties of the computing elements using measurer apparatuses and to store local information representing the physical performance properties in individual memory of those computing elements;
• each computing element including a processing unit and the individual memory and
• to collect remote information representing the physical performance properties from the individual memory in a particular computing element using a collector apparatus and to store the remote information as replicate information in the individual memory of another computing element;
• wherein the remote information is collected using third party access.

A computer system comprising a plurality of networked computing elements, each element including a processing unit and individual memory, the computer system including a fault-tolerant monitoring apparatus arranged to monitor physical performance properties of the networked computing elements, the monitoring apparatus comprising

• a plurality of measurer apparatuses each arranged to measure the physical performance properties of a single computing element, for storage as local information in the individual memory of the particular single computing element;
• and
• collector apparatus arranged to collect remote information representing physical performance properties from individual memory in a plurality of the computing elements and to store the remote information as replicate information in the individual memory of another computing element;
• wherein the remote information is collected using third party access.
