Sub-agent Description
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.
• 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.
For more information on threshold configurations, see the HP Systems Insight Manager Help file. This
guide can be found on the Management CD or on the HP website at
www.hp.com/go/hpsim.
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 5.

Sub-agent Description
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
• IDA physical drive information
The IDA Agent is located in /opt/hp/hp-snmp-agents/storage/bin/cmaidad. The suggested poll_time is
15 seconds (default). The minimum recommended poll_time is 5 seconds.
