Abstract: The collection of performance data at multiple servers in a SAN and forwarding that data to a centralized server for analysis is disclosed. Remote agents and a central server application collect specific interesting negative event data to enable a picture of the operational health of the SAN to be determined. The agents are placed in servers having HBAs acting as initiators. The agents interact with the HBAs through a driver stack to collect event data. Because of the initiator function they perform, HBAs have visibility to parts of the network that other entities do not have access to, and thus are ideal locations for gathering event data. A SAN diagnostics manager then pulls the collected data from each agent so that a “picture” of the SAN can be developed. In addition to collecting initiator data, the agents also collect errors and performance data from the OS of the servers.

Abstract: Some implementations provide techniques and arrangements for causing an interrupt in a processor in response to an occurrence of a number of events. A first event counter counts the occurrences of a type of event within the processor and outputs a signal to activate a second event counter in response to reaching a first predefined count. The second event counter counts the occurrences of the type of event within the processor and causes an interrupt of the processor in response to reaching a second predefined count.

Abstract: Mechanisms for controlling rollover or reset of hardware performance counters in the data processing system. A signal indicating that a rollover or reset of a first hardware performance counter has occurred is received and it is determined if the first hardware performance counter is analytically related to one or more second hardware performance counters based on defined ganged hardware performance counter sets. A signal is sent to each of the one or more second hardware performance counters in response to a determination that the first hardware performance counter is analytically related to the one or more second hardware performance counters. Each of the one or more second hardware performance counters is reset to an initial value in response to the one or more second hardware performance counters receiving the signal from the ganged hardware performance counter rollover/reset logic.

Abstract: Topology discovery of a target system having a plurality of components coupled with a scan topology may be performed by driving a low logic value on the data input signal and a data output signal of the scan topology. An input data value and an output data value for each of the plurality of components is sampled and recorded. A low logic value is then scanned through the scan path and recorded at each component. The scan topology may be determined based on the recorded data values and the recorded scan values.

Abstract: Apparatus, methods, and other embodiments associated with reducing metadata controller communication volume are described. One example apparatus produces tracking data by tracking metadata controller communications and then controls which of two different types of metadata controller communication message types are used for metadata controller communications based, at least in part, on the tracking data. One message type provides actual state and/or location information about a metadata controller. A second message type provides only information about the state and/or location information available at a metadata controller. Selectively using the second message type facilitates reducing metadata controller communication volume.

Abstract: The present invention extends to methods, systems, and computer program products for integrating external and cluster heat map data. Embodiments of the invention include a proxy service that manages (e.g., asynchronous) communication with cloud nodes. The proxy service simulates packets to on-premise services to simplify the integration with an existing heat map infrastructure. The proxy maintains a cache of performance counter mappings and timestamps on the on-premise head node to minimize the impact of latency into heat map infrastructure. In addition, data transfer is minimized by mapping a fixed set of resource based performance counters into a variable set of performance counters compatible with the on premise heat map infrastructure.
