ETERNUS SF Disk Space Monitor User's Guide - Microsoft(R) Windows Server(TM) 2003/Solaris(TM) Operating System/Linux - 13.0

2.1 Overview

This section explains an overview of ETERNUS SF Disk Space Monitor.

2.1.1 Monitoring and assessment functions

The functions provided by ETERNUS SF Disk Space Monitor can be broadly divided into a monitoring function and an assessment function.

For the monitoring function, the Monitor function is provided in order to monitor whether the entire system is operating properly, or whether errors have occurred. (The Monitor function includes the threshold monitoring function.) If some kind of error has occurred, the Drill Down function is provided in order to isolate the problem by analyzing detailed information about resources.

For the assessment function, the Report function is provided in order to periodically evaluate the system over certain periods of time.

ETERNUS SF Disk Space Monitor provides functions that support both the monitoring and assessment aspects of operation management.

2.1.2 Basic Component Configuration

This section explains the configuration and basic behavior of ETERNUS SF Disk Space Monitor components using the following figure.

With ETERNUS SF Disk Space Monitor, performance information is collected by Agents installed on managed servers. The performance information collected by each Agent is sent to a Manager, where it is stored in a performance database (PDB). The information stored in the PDB can be looked up using the display functions provided on the operation management client.

The information of disk space is included in resource data (10 min, 1 week).

SpaceMonitor shows from the information of disk space of resource data.

The folder-shaped sections in the figure above (such as "DsaPDBWriter" and "DsaForwarder") represent directories that are important for the behavior of Managers and Agents. These directories are explained the sections that follow.

2.1.3 Collection policies and configuration information 

ETERNUS SF Disk Space Monitor provides templates that include collection items recommended by Fujitsu. Create and apply policies by adjusting these templates to the characteristics of the systems being managed.

This enables the necessary information to be continuously collected without any advanced skills relating to performance.

As shown in the figure above, policies are created and applied by executing commands on Agents. At this point, the policies are created from the template and configuration information. (Configuration information is used to automatically detect objects that can be managed.)

Configuration information is sent to the Manager, where it stored in the PDB.

When environment setup is performed on the operation management client, this configuration information is referenced, and the information collected for the system can be displayed in a tree structure.
