1-2 Insight Management SNMP Agents for HP ProLiant (hp-
snmp-agents)
The ProLiant Insight Management Agents provide proactive notification of server events through the HP
Systems Insight Manager console. Alternatively, the ProLiant Insight Management Agents allow the status of
the server to be monitored or checked using a standard Web browser. Insight Management Agents include
the following:
• Server Agents (consist of Server Peer Agent, Host OS Agent, Threshold Agent, Standard Equipment
Agent, and System Health Agent)
• Storage Agent (consists of IDA, IDE, SCSI, SAS, and FCA Agents, and Event Agent)
• Network Agent
1-2-1 Server Agent
A Server Agent consists of the sub-agent components listed in Table 6.

Sub-agent Description
Server Peer Agent The Peer Agent extends the SNMP "enterprise" Management Information Base (MIB) to include HP
specific data, specifically enterprise ID 232. The Peer agent supports SNMP get, set, and trap
operations on MIB branches under "enterprises.232." At SNMP agent startup, cmaX reads MIB
information files referenced in the master file /opt/hp/hp-snmp-agents/mibs/cmaobjects.conf. These
referenced MIB information files are /opt/hp/hp-snmp-agents/mibs/cmasvrobjects.conf and
/opt/hp/hp-snmp-agents/mibs/cmafdtnobjects.conf.
During installation, the Peer Agents are configured to start automatically when the SNMP agent is running
and should be started after the SNMP agent snmpd is started and should be killed after snmpd is killed.
Host OS Agent The Host OS Agent gathers data for the Host OS MIB, including:
• Server/host name and operating system version number
• Linux file system information for each mounted filesystem
• Software version information
The Host OS Agent executable is /opt/hp/hp-snmp-agents/server/bin/cmahostd
Threshold Agent The Threshold Agent implements the Threshold MIB. Users can set thresholds on counter- or gauge-type
MIB variables. The Threshold Agent periodically samples each selected MIB variable at a rate defined
by the user.
MIB data values are compared to user-configured thresholds. If a configured threshold is exceeded, an
alarm trap is sent to the configured SNMP trap destination and to Linux email (configurable through
trapemail entries in /opt/hp/hp-snmp-agents/cma.conf file). User-configured alarm thresholds are
permanently saved in the data registry until deleted by the user.
The Threshold Agent executable is /opt/hp/hp-snmp-agents/server/bin/cmathreshd.
Standard
Equipment Agent
(cmastdeqd)
The Standard Equipment Agent gathers data for the Standard Equipment MIB. The data
includes:
• PCI slot information
• Processor and coprocessor information
