HP Insight Management Agents 9.20 Managing ProLiant Servers with Linux HOW TO Whitepaper

1 Software architecture
This section describes the features and architecture of the following HP Linux management software:
• HP System Health Application and Command Line Utilities (hp-health)
• Insight Management SNMP Agents for HP ProLiant Systems (hp-snmp-agents)
• HP System Management Homepage (hpsmh)
• Descriptions for HP management consoles for Linux
HP System Health Application and Command Line Utilities(hp-health)
The System Health Application and Command Line Utilities (hp-health) package collects and
monitors important operational data on ProLiant servers. Contained within the (hp-health)
package are the following components:
• Health Monitor
• HP Integrated Management Logging (IML) utility (hplog)
• HP Unique Identifier utility(hpuid)
• HP ProLiant Boot Configuration Utility (hpbootcfg)
• HP Management Command Line Interface (hpasmcli)
ProLiant servers are equipped with hardware sensors and firmware to monitor certain abnormal
conditions, such as temperature readings, fan failures, and error correction coding (ECC) memory
errors. The Health Monitor monitors these conditions and reports them to the administrator by
printing messages on the console (preserved in /var/log/messages). The Health Monitor also
logs the conditions to the ProLiant IML. The IML is a dedicated, Non-Volatile RAM (NVRAM) that
can be viewed and maintained by the hplog application or iLO web interface.
ProLiant servers contain an Integrated Lights-Out (iLO) controller that, with optional software, allows
secure remote management of the server, including IML management and graphical remote console.
The System Health Application and Command Line Utilities (hp-health) package works with
the HP ProLiant Channel Interface Device Driver for iLO (iLO/iLO 2/iLO 3/iLO 4) package
to provide secure remote management of the server, including IML management and graphical
remote console. The hp-health package includes four applications (listed in Table 1 (page
5)). One of these modules is automatically selected at start-up, depending on the HP ProLiant
Advanced System Management (ASM) hardware available and the base packages installed.
NOTE: To determine the type of HP ProLiant Advanced System Management hardware installed,
check the ProLiant server specifications located on http://www.hp.com.
