• Standard peripheral information (serial ports, diskette drives, and so on)
The Standard Equipment Agent executable is /opt/hp/hp-snmp-agents/server/bin/cmastdeqd.
System Health
Agent
(cmahealthd)
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 (cmarackd)
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.

1-2-2 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.

IDA Agent
(cmaidad)
The IDA Agent gathers data for the IDA MIB. The data includes:
• IDA controller information
• IDA accelerator information
• IDA logical drive information
