Overview

The primary aim of the Process 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.


Process Knowledge Base Version

Version Availability Date Min Sentinel
Version
1.2 14th Mar, 2004 4.4.1


Process Knowledge Base

Processes Class

Sentry AIX HPUX Linux SCO Solaris Tru64 Windows
CPU_Hogs
Important_Processes
Memory_Hogs
Event_Manager
Host_Monitor
NOTE
Process Knowledge Base includes the Process Management Console, provided as an action against the Processes sentry class.

¹ On certain OSes the Processes sentry is turned off by default. Certain instances are provided as examples (nmdb, smdb) only, but should be changed to reflect the system on which the KB is installed. Note also that system services (daemons) are normally monitored via the Services sentry, so check in the Services folder before adding processes to be monitored.
