Table 6 Sub-agents of the Server Agent (continued)
DescriptionSub-agent
The System Health Agent gathers data for the Health MIB. The data collected includes critical
(NMI) errors, correctable memory (ECC) errors, system hang/panic detection, temperature
conditions, and fan failures. The System Health Agent then retrieves these errors from the Health
Monitor. The System Health Agent executable is
/opt/hp/hp-snmp-agents/server/bin/cmahealthd.

System Rack agent gathers data for the Rack MIB for P-Class and also monitors the rack health
through system management. The data collected includes:
• Onboard Administrator
• Onboard Administrator IP address
• Enclosure Serial Number, Enclosure Product ID, Enclosure firmware revision
The System Rack Agent executable is /opt/hp/hp-snmp-agents/server/bin/cmarackd.

Storage agent
The Storage agent consists of IDA, IDE, SCSI, SAS and FCA Sub-agents, and Event Agent
components. The Storage agent collects information from the Fibre Channel, drive array, SCSI,
SAS, and IDE subsystems at periodic intervals, makes the collected data available to the SNMP
agent, and provides SNMP alerts.
Each Storage Data Collection Agent gathers and saves Storage MIB data to files in the Storage
Data Registry. The Data Collection Agents periodically update MIB data at configurable poll
intervals.
The agent responsible for managing the selected MIB data item performs SNMP set commands.
Data Collection Agents generate SNMP trap commands.
The Storage data registry (/var/spool/compaq/hpasm/registry) is composed of standard
Linux directories and associated files. Each file in the data registry is a logical object containing
“n” related data items.
The -p poll_time command line argument, which can be used with the Storage Agents, specifies
the number of seconds to wait between data collection intervals. The minimum allowed value is 1
second and the default value is 15 seconds.
Increasing the agent poll_time setting improves system performance but decreases the data collection
rate. Conversely, decreasing the agent poll_time setting increases the data collection rate but may
decrease system performance.
A Storage Agent consists of the sub-agent components listed in Table 7: “Sub-agents of the Storage
Agent”.
