ABSTRACT:
The present invention provides a system and method that aggregates and processes monitoring data acquired inside a monitored application outside of the said application to reduce overhead caused by monitoring tasks in the monitored application. Monitoring data acquired by monitoring sensors is stored in a ring buffer after acquisition, which decouples acquisition of data and its transfer, enabling asynchronous sending of performance data to a monitoring server for analysis. Memory consumption of said ring buffer is limited to a fixed size which keeps memory consumption caused by monitoring processes low and predictable. Correlation, analysis, all computation of monitoring data, and bytecode manipulation to place sensors is performed outside of the monitored application, by a monitoring server.
