Abstract: Provided are a computer program product, system, and method for modifying output code in source code to output compressed output statements. A codebook indicates replacement codes associated with strings in output code in source code. The output code is to generate output statements. The strings of the output code are replaced with the replacement codes associated with the strings to produce modified source code. Multiple instances of a same string in the output code are replaced by an associated same replacement code in the codebook. The modified source code, having the replacement codes replacing the strings, is compiled to produce an executable application. The executable application during runtime produces compressed output statements comprising the replacement codes that replaced the associated strings.

Abstract: A method, computer system, and a computer program product for automatic processing of computer logging events may be provided. In one embodiment, the process comprises determining an application priority model relating to a plurality of computer applications being executed on a device. A usage pattern model is also determined by monitoring utilization of the plurality of applications based on usage of the applications by a priority of users. A log flow control policy is also determined using logging information. All determined models also use a set of metrics to derive a log flow rules. These rules are used to manage log flow control policies when processing a plurality of logs.

The joint plan including a set of virtual resources, a set of billing contracts, and a set of load balancer weights. The HRR manager further configured to implement the joint plan for a distributed computing workload during the future time interval.

Abstract: A method, system and computer program product, the method comprising: in response to receiving a packet from a stream of packets transmitted to a computing platform, determining, based on a meta-data of the packet, whether to capture the packet or avoid capturing thereof, said determining comprising: subject to the meta-data indicating that a sequence number of the packet is within a first range or within a second range, wherein a distance between an end of the first range and a beginning of the second range is at least of a predetermined size, wherein a distance, through a wraparound, between an end of the second range and a beginning of the first range is at least of the predetermined size, thereby a wraparound situation is identifiable within the stream of packets; and in response to determining to capture the packet: capturing the packet; and transmitting the packet to analysis.

Abstract: Embodiments of the present invention provide methods, computer program products, and systems for fulfilling a service chain request. Embodiments of the present invention can be used to collect network data of a plurality of instances of services and connections between the plurality of instances of services and redefine service chains to direct flow to an alternative instance of a service responsive to determining that an instance of a service in a service chain has become inaccessible. Embodiments of the present invention can be used to fulfill a service chain request and avoid one or more instances of services (and/or connections there between) that could cause a delay between transmitting data packets through the service chain.

Abstract: Multiple target blocks on a first storage device are allocated to store a target object. The target blocks are arranged to be in a one-to-one correspondence with multiple source blocks of a source object. The target blocks are set to a non-populated state, and target blocks in the non-populated state are populated with data from corresponding source blocks. While the target blocks are being populated, if a request is received to retrieve data from one of the target blocks that is in the non-populated state, then the one of the target blocks is populated with the data from the corresponding source block and set to a populated state.
