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.

Certain operating systems do not provide all the CPU statistics by default, and collecting them may require kernel patches or third party collection tools. Solaris requires packages SUNWaccr and SUNWaccu. Tru64 requires …

¹ All operating systems monitor % System, % User and % Idle CPU time, some OSes provide more information:

OS	More CPU_States Information	Description
AIX, Solaris, Tru64	% Wait IO	The amount of time spent waiting for blocked I/0 to complete.

² Linux provides a complete service management interface using chkconfig and the startup/shutdown scripts in /etc/init.d (/etc/rc.d/init.d on older systems). This interface has been implemented via actions on the Services sentry on Linux.

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.
