1. A fault-tolerant monitoring apparatus arranged to monitor physical performance properties of a plurality of networked computing elements, each computing element comprising a processing unit and individual memory to store local information from the computing element itself and remote information from other computing elements, the monitoring apparatus comprisinga plurality of measurer apparatuses, each arranged to measure the physical performance properties of a single computing element among the plurality of computing elements, the physical performance properties being stored as local information in the individual memory of the single computing element in which the measurement is made;

  • andat least one collector apparatus,each measurer apparatus, among the plurality of measurer apparatuses, being directly linked to a single collector apparatus among the at least one collector apparatus without involvement of a network interface controller to signal the collector apparatus with local information,each collector apparatus arranged to control,collection of remote information representing the physical performance properties from the individual memory in a plurality of the computing elements, andstorage of the remote information as replicate information in the individual memory of another computing element;

    wherein the remote information is collected by a computing element other than the computing element from which the remote information is collected using third party access, and the remote information is stored as replicate information in the individual memory of the computing element which collected the remote information, or another computing element other than a computing element from which the remote information is collected using the third party access;

    wherein the physical performance properties are in form of electrical characteristics including any of voltage, current power or energy use of the computing element or part thereof; and

    wherein the third party access is by one of remote direct memory access (RDMA) put and RDMA get.
