Abstract: Business transactions and the nodes processing the transactions are monitored and actions are applied to one or more nodes when a performance issue is detected. A performance issue may relate to a metric associated with a transaction or node that processes the transaction. If a performance metric determined from data captured by monitoring does not satisfy a health rule, the policy determines which action should be performed to correct the performance of the node. When a problem is detected for multiple nodes, the present technology may address a subset of the multiple nodes rather than apply an action to each node experiencing the problem. When a solution is found to correct the problem with the subset of nodes, the solution may be applied to the other nodes experiencing the same problem.

Abstract: A system and method for tracing individual transactions on method call granularity is disclosed. The system uses instrumentation based transaction tracing mechanisms to enhance thread call stack sampling mechanisms by a) only sampling threads executing monitored transactions while execution is ongoing b) tagging sampled call stacks with a transaction id for correlation of sampled call stacks with instrumentation bases tracing data. The combination of instrumentation based tracing with thread call stack sampling reduces sampling generated overhead by only sampling relevant thread, and reduces instrumentation generated overhead because it allows reducing instrumentation.

Abstract: According to one aspect of the present disclosure, a system and technique for capacity forecasting is disclosed. The system includes a host having a processor unit and a memory. Resource data stored associated with an environment is stored in the memory, the resource data comprising inventory information of applications, processing resources and storage resources of the environment. A ledger module is executable by a processor unit to: create a capacity-associated transaction; identify and link at least one of an application, processing resource and storage resource to the transaction from the resource data; determine an initiation time and duration associated with the transaction; and forecast a change in capacity of at least one linked storage resource for the transaction and a time of the change in capacity.

Abstract: Systems and methods for performance and security management of the computing infrastructure that supports an application deployed in a hosted computing environment are described. In one embodiment, for example, a system comprises agents installed on hosts. The agents capture and record system events from operating systems on the hosts that result from application component processes executing on the hosts. The system further includes a collection and analysis engine that obtains captured and recorded system events from the agents, identifies captured and recorded system events that pertain to an application transaction, and produces, from the identified system events, metric data reflecting quantity of computing resources used by the application component processes to process the application transaction. The system also includes a web dashboard that presents the metric data to a user, for example, on a web page.

Abstract: An exactly once semantics (EOS) system of a storage input/output (I/O) stack implements a technique ensuring that non-idempotent operations occur exactly once in a storage system embodied as a node of a cluster. Illustratively, a first layer of the storage I/O stack may act as a client issuing a non-idempotent operation to second layer of the stack, which may act as a server. According to the technique, the EOS system may wrap (i.e., encapsulate) the non-idempotent operation within a transaction embodied as an EOS transaction data structure having a transaction identifier that uniquely identifies the transaction. The server may complete the transaction and reply with a result to the client, which may acknowledge receipt of the reply. In response to a crash and subsequent recovery of the node, the EOS system may determine whether the transaction had completed prior to the crash. If so, the EOS system ensures that the transaction is not re-played (re-executed). Otherwise, the EOS system allows execution of the transaction such that the transaction occurs exactly once.

Abstract translation: 一个存储输入/输出（I / O）堆栈的完全一次语义（EOS）系统实现了一种技术，确保非特权操作在体现为集群节点的存储系统中发生一次。 示例性地，存储I / O堆栈的第一层可以充当向堆叠的第二层发出非幂等操作的客户端，其可以充当服务器。 根据该技术，EOS系统可以将具有具有唯一地识别交易的事务标识符的EOS事务数据结构体现的事务中的非幂等操作包裹（即封装）。 服务器可以完成交易并将结果回复给客户端，这可以确认收到回复。 响应于节点的崩溃和随后的恢复，EOS系统可以确定事务在崩溃之前是否已经完成。 如果是这样，EOS系统确保事务不被重新播放（重新执行）。 否则，EOS系统允许执行事务，使得事务正好发生一次。

Abstract: Embodiments of the invention relate to implementing run-time instrumentation indirect sampling by address. An aspect of the invention includes a method for implementing run-time instrumentation indirect sampling by address. The method includes reading sample-point addresses from a sample-point address array, and comparing, by a processor, the sample-point addresses to an address associated with an instruction from an instruction stream executing on the processor. The method further includes recognizing a sample point upon execution of the instruction associated with the address matching one of the sample-point addresses. Run-time instrumentation information is obtained from the sample point. The method also includes storing the run-time instrumentation information in a run-time instrumentation program buffer as a reporting group.

Abstract: Embodiments of the present invention disclose a method for recovery of a two-phase commit transaction. A computer transmits a first transaction identifier to a data store, wherein the first transaction identifier defines a two-phase commit transaction. The computer transmits a prepare command for the first transaction identifier to a first resource manager. The computer determines if a failure and restart occurred within a distributed data processing environment, wherein the failure and restart occurs after the first resource manager receives an end command, but prior to completing execution of the prepare command for the first transaction identifier. Responsive to determining the failure and restart did occur within the distributed data processing environment, the computer retrieves the first transaction identifier from the data store. The computer transmits a rollback command for the retrieved first transaction identifier to the first resource manager.
