Overview
The primary aim of the Informix knowledge base in Sentinel3G is to provide notification of CPU and memory hungry processes using monitoring that is consistent across various UNIX, Linux and Windows platforms. Due to differences between the various operating systems we monitor, complete consistency is not always achievable. This document describes the general content of the Process knowledge base, and the discrepancies between them on different platforms.
