The current application is directed to crosscutting functionalities, including byte-code instrumentation, error logging, and other such crosscutting functionalities. These crosscutting functionalities generally violate, or run counter to, modern code-development strategies and programming-language features that seek to partition logic into hierarchically organized compartments and modules with related functionalities, attribute values, and other common features. In particular, the current application is directed to byte-code instrumentation introduced into a computer program for collecting data, such as execution traces, elapsed times for routine execution, and other information at run time for logging and subsequently manual, semi-automatic, or automatic analysis. The current application is particularly directed to byte-code instrumentation that automatically filters collected data in order to log only data having greatest value for subsequent analysis.

Filtering data frames using program instrumentation

In one embodiment, a method for processing trace data is provided. The method generates trace data during execution of the target application and obtains criteria for identifying whether a value in the trace data is sensitive. An initial occurrence of a sensitive value in the trace data is identified based on the obtained criteria. The method then stores the sensitive value in a data structure accessible by an obscuring process. The obscuring process receives the trace data and obscures occurrences of the sensitive value in the trace data prior to providing the trace data for display.

Marking and obscuring sensitive values in traces

The current application is directed to flexible and run-time-modifiable implementation of crosscutting functionalities, including code instrumentation, error logging, and other such crosscutting functionalities. These crosscutting functionalities generally violate, or run counter to, modern code-development strategies and programming-language features that seek to partition logic into hierarchically organized compartments and modules with related functionalities, attribute values, and other common features. One feature of the methods and systems for implementing crosscutting functionalities to which the current application is directed is an intelligent switch that can be controlled, at run time, to alter invocation and behavior of crosscutting-functionality implementations, including data-collection instrumentation, error logging, and other crosscutting-functionality implementations.

Flexible and run-time-modifiable inclusion of functionality in computer code

Method and system that filters byte-code instrumentation at the instrumentation level

A method for storing time series data in a key-value database includes receiving time series data relating to the occurrence of an event. An addressing scheme that defines attributes for inclusion in keys for the event is analyzed. The attributes include time granularity attributes of different sizes. The method generates a key corresponding to the time series data based on the analyzing of the addressing scheme including attributes specified in the addressing scheme that are related to the event and one of the attributes represents one of the plurality of time granularity attributes. The method further issues a command to the key-value database to store a record of the occurrence of the event as a value in the key-value database where stored values in the key-value database corresponding keys may be used to satisfy queries relating to the event over a range of time.
