Overview
The primary aim of the operating system knowledge bases in Sentinel3G is to provide a base level of operations monitoring that is consistent across various UNIX/Linux 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 OS knowledge bases, and the discrepancies between them on different platforms.
Standard Knowledge Base
The standard knowledge base is OS independent, and so is packaged with Sentinel3G on all Operating Systems. It can be upgraded, but not uninstalled.

¹ Connectivity and Event_Manager sentries are only started on the Event Host.
² Scheduler sentry is not started by default. Please read the online documentation for details on how to use the Scheduler sentry.

¹ Packets sent and received are known only as sent and received on Solaris and Linux.
² The BadSU agent is a LogFile agent, and so does not have a poll time. Any new data is interpreted whenever the logfile being monitored changes.
³ The Information agent (Hardware agent on Linux) is essentially run only once.
