A method, system and computer program product for locating business rules in application source code. Static code analysis is performed on the application source code to collect variable usage and statement information, which is stored in a repository. Variables that are used in conditions and computational statements are identified using the stored information, including determining the usage distribution of these variables in such conditions and computational statements and whether such conditions and computational statements are within copybooks. A score is assigned to these identified variables based on usage and if their usage is shared in copybooks. Those variables with a score exceeding a threshold value are selected to be inserted in a list of business terms. Usage locations of the variables in the list are extracted. The business rules in the application source code containing the logic using these variables are then identified based on the extracted usage locations.

An aspect of the disclosure includes a natural gas leakage detection device. The natural gas leakage device includes a metering interface for detecting usage of natural gas. A clock is provided to determine time of day and one or more predetermined times when no natural gas usage is expected. A first sensor is used to determine whether a furnace is operating. A monitoring device is provided. The monitoring device being operable during the one or more predetermined times when no natural gas usage is expected, to monitor the metering interface and the first sensor and to perform an action in response to natural gas usage being detected during the one or more predetermined times when no natural gas usage is expected and the first sensor determines that the furnace is not operating.

Provided are methods, apparatus and computer programs for monitoring operational data relating to a sequence of data processing operations in a network of data processing units. In response to specified boundaries for data gathering, operational data is selectively gathered into discrete data partitions for a desired time period, a desired set of processing nodes, and/or a desired set of process executions. A set of event listeners invoke operations of a data gatherer in response to events within a processing sequence and the data gatherer allocates operational data to different ones of a set of discrete logical data containers in response to notifications from the event listeners. The data collection is responsive to system events such as a collection interval expiry to end data collection for a first partition and start data collection for a second partition.
