Product architecture

HP Insight Management Agents for Tru64 UNIX operate on hardware devices hosted by AlphaServer systems. They provide hardware instrumentation to enable fault, performance, configuration and asset management.

The Management Agents use Industry Standard Simple Network Management Protocol (SNMP) and the Hypertext Transfer Protocol (HTTP).  The web-enabled agents render information dynamically in HTML so that it can be viewed from a standard browser located anywhere on the network. The agents also provide a level of integration with SysMan and SysCheck, sharing the HTTP service agent and the Home Page (figure 1).

The System Management Homepage, supported on Tru64 UNIX v5.1A and above, is a Web-based application that provides a consolidated interface for single system management. The System Management Homepage provides a common, easy to use interface by aggregating the data from HP web-based agents and management utilities (figure 2).

  • HTTP Server - Handles all the communication outside the object being managed. It proxies all external requests and replies, and handles all security for the Web agents. The System Management Homepage software on Tru64 UNIX v5.1A and above, proxies to this HTTP server and handles all external HTTP requests.

  • Data Rendering - Creates an HTML page. When it receives a request, it reads the corresponding template page and creates a new HTML page. The data tags are replaced with actual data or JavaScript objects. The resulting page is then returned to the HTTP server.

  • Data Acquisition - Services the data request from the data rendering engine. It uses MIB.BIN to translate Data names to Object Identifiers (OID) and then uses the OIDs to retrieve SNMP MIB data.

The SNMP Management Agents perform in-depth monitoring of devices by collecting and measuring critical parameters. These parameters indicate the current state of subsystems by counting the occurrences of particular events (for example, the number of read operations performed on a disk drive) or by monitoring the state of a critical function (for example, whether the cooling fan is operating). The subsystems that the agents monitor include Configuration, Mass Storage, Networking, Utilization, and Recovery. Figure 4 below is an example of the web display.

Product specifications

HP Insight Management Agents for Tru64 UNIX consist of the following software components:

  • HTTP web server library ( libcpqhmmo.so ). This is a shared library which provides HTTP V1.0 services as well as the ISAPI protocol used by the Hyper Media Managed Objects (HMMOs)

  • Insight Manager Web Agent ( insightd ). This is the agent responsible for the data acquisition and data rendering. It converts SNMP raw data to formatted web pages.This daemon does not exist on CPQIM360 onwards on Tru64 UNIX v5.1A and higher, as it has been converted into a System Management Homepage webapp.

  • SNMP subagents ( cpq_mibs ). These are the ESNMP subagents implementing the Compaq Enterprise MIBs including cpqhost.mib, cpqsinfo.mib, cpqstdeq.mib, cpqscsi.mib, cpqhlth.mib, cpqnic.mib, and cpqide.mib.=

  • Threshold subagent ( cpqthresh_mib ). This is a general purpose alarm and threshold subagent, implementing Compaq's settable Threshold MIB, cpqthrsh.mib.

  • SysMan HMMO ( sysman_hmmod ). This management module is responsible for registering SysMan with the management agents and rendering the SysMan Home Page. This daemon does not exist on CPQIM360 onwards on Tru64 UNIX v5.1A and higher, as it has been converted into a System Management Homepage webapp.

  • Config HMMO ( config_hmmod ). This management module is responsible for registering SysCheck with the management agents and rendering the Sys_Check report.This daemon does not exist on CPQIM360 onwards on Tru64 UNIX v5.1A and higher, as it has been converted into a System Management Homepage webapp.

  • GS Discovery HMMO ( gshmmod ). This management module only runs on AlphaServer GS80/160/320 Series. Used to discover GS series platforms on a single subnet of a LAN. Provides a consolidated view of the discovered platforms along with any active partitions running Tru64 UNIX or VMS.

  • Storage subagents ( cpqstor_mib ). These are the SNMP subagents implementing the Compaq Enterprise Storage MIBs including, cpqida.mib, cpqfca.mib, and cpqstsys.mib.

  • Performance subagent ( pmgrd). This is the SNMP subagent implementing the Tru64 UNIX Performance MIB, pm.mib. This version is an update from the base OS version which now provided Disk I/O rate, and integrated NFS Statistics.

  • SNMP Trap to EVM conversion utility ( snmpevmd ). This agent monitors SNMP traps and posts corresponding Tru64 UNIX Event Manager (EVM) events.  The user can customize this agent by specifying the SNMP traps to be processed in a simple configuration file.  Custom EVM templates can also be provided to describe the traps received.

  • The System Management Homepage software ( hpsmhd ) supported on Tru64 UNIX v5.1A and above, is the master HTTP server providing the consolidated home page and web interface for all other HP web based software installed on the system.
