Abstract This technology brief provides an overview of the HP Insight Management Agents for HP ProLiant servers running the Windows® server operating system. It is intended to provide an architectural overview of the entire set of client-side software components that are installed on ProLiant servers to provide integrated manageability using the HP Systems Insight solution.

HP Insight Management agents The four HP Insight Management agents are the core of the architecture on managed servers. As a group, they are responsible for collecting all of the management information about the server and its software environment. As the information is collected, it is stored in the Windows Registry. Using SNMP protocol, Insight processes such as HP SIM server and the System Management Homepage (or other SNMP-based management tools) access this information and then display it to the user.
Server agent The Server agent collects the basic server information, including the server’s key subsystems configurations and health information. Table 2 lists the categories of information that the Server agent collects and the sources from which this information is obtained. Table 2.
The Storage agent and Insight Management Agents are designed to collect and report information on storage that is viewed as belonging to the single host server. Multi-host storage on the network, such as SANs, is not reported through the Insight Management Agents. It is managed using WBEM-based Storage Management Initiative Specification (SMI-S) Storage Providers.
SNMP Services The SNMP Services enable the flow of basic management information between the managed server and HP SIM. These components process SNMP Gets and Sets, as well as the SNMP Traps used in alerting. Microsoft SNMP Agent Service The Microsoft SNMP Agent Service provides the core set of SNMP services used by the Insight Management system on the managed server.
Performing SNMP Sets SNMP Sets are used to define the alerting thresholds for management information or to set SNMP configuration information. Because these operations are considered sensitive, the Insight Management architecture does not send SNMP Sets over the open SNMP connection between SIM and the managed server.

Additional Insight Agents functionality The HP Insight Agents architecture provides additional functionality that is unique to the HP SIM solution environment. The HP Insight Event Notifier The HP Insight Event Notifier service provides a mechanism for the Insight Management Agents architecture to send e-mail notifications to specified recipients when alert events occur on the managed server.
Process Monitoring The HP Insight Management Agents architecture can also monitor and alert on any active processes running on a managed server and send alerts as necessary. This functionality is part of the Foundation Agent. It can be configured using the HP Management Agents configuration utility accessible from the Control Panel of any managed server with the Insight Management Agents architecture installed (Figure 4).

The System Management Homepage framework The System Management Homepage framework plays several roles in the Insight Management Agents architecture. It retrieves and displays the detailed management information for a managed server through the System Management Homepage. The framework also provides a set of services that are integral to delivering many of the special features that are part of the overall Systems Insight Management solution.
System Management Homepage The System Management Homepage itself is a set of active web pages that aggregate a system’s management information for display as part of the overall HP Systems Insight Manager solution. As shown in Figure 7, the management console displays general descriptive information about the managed server, and presents information that was gathered by the HP SIM server over the standard SNMP connection.
HTTPS, single sign-on, and secure task execution An additional role of the SMH framework is to provide a secure communications environment for the Insight Management Agents architecture. SNMP does not provide secure, encrypted communications between the managed server and the remote requesting process. To address this, the SMH framework implements HTTPS, a separate, SSL-based, secure communications link and protocol between each managed server and the SIM server.
Considerations when installing and configuring the Insight Agents Updating Insight Management Agents In addition to the latest device drivers and utilities for HP ProLiant servers, the ProLiant Support Packs contain updated Insight Management Agents. ProLiant Support Packs are developed and tested concurrently with HP SmartStart releases.
Setting the server role System Administrators can use the Insight Management Agents architecture to define server Roles for any servers being managed using HP SIM. The Server Role is a user-defined string of up to 256 characters. It is typically used to identify a server’s function in the network or even its physical location.
Additional support for Insight Management on HP ProLiant servers Support for management of HP ProLiant servers using HP SIM continues to expand in response to the need for more systems management in increasingly complex environments. HP Insight Management WBEM Providers The HP Insight Management Web-Based Enterprise Management (WBEM) Providers offer an alternative to the SNMP-based Insight Agents for collecting and delivering managed system information to HP SIM.
