management interface include the hpasm package. You can use the /sbin/hplog utility to
display the following environment data:
• Thermal sensor data
• Fan data
• Power data
In addition, most hpasm errors are logged to the syslog system logger. For more information,
see hpasm(4) and hplog(8).
7.4 Monitoring Disks
The Self-Monitoring, Analysis and Reporting Technology (SMART) system is built into many
IDE, SCSI-3, and other hard drives. The purpose of SMART is to monitor the reliability of the
hard drive, to predict drive failures, and to carry out different types of hard drive self-tests.
Under HP XC, the smartd daemon monitors the SMART system on the CP6000 series. This
daemon writes all disk events to syslog. The Nagios check_syslogalerts plug-in is
configured to generate a Nagios alert for all smartd events in the consolidated log file.
NOTE: The smartd daemon only works on SCSI and IDE physical devices. It does not work
on drives attached to Smart Array cards or on logical drives in a hardware RAID configuration.
To modify the default configuration of the smartd daemon, you can use the
/opt/hptc/smartd/etc/smartd.conf template file. For more information on this file, see
smartd.conf(5).
For more information on the smartd daemon, see smartd(8).
7.5 Displaying System Statistics
The HP XC System Software provides two methods for displaying system statistics: by issuing
commands from a host's command line or using the Nagios Web-based interface.
7.5.1 Displaying System Sensors from the Command Line
The shownode metrics sensors command displays the system sensors, their value, and a
brief description, with a date and time stamp. Sensor data includes the position of switches and
jumpers, temperature data, fan speeds, and so on.
The following example shows sensor data for node n14; some results are truncated horizontally
to fit on the page.
# shownode metrics sensors n14
Timestamp |Node_Id |Name |Value |Description
---------------------------------------------------------------------------
date and time stamp |n14 |Sensor count |29 |Sensors within threshold; ok
Individual sensors are displayed only when a sensor is out of range. Otherwise a sensor count
is displayed.
Invoking the command without specifying a node displays the sensor data for all the nodes in
the HP XC system as the following example shows. The output is truncated horizontally to fit
on the page.
# shownode metrics sensors
Timestamp |Node_Id |Name |Value |Description
---------------------------------------------------------------------------
date and time stamp |n15 |Sensor count |29 |Sensors within threshold; ok
date and time stamp |n14 |Sensor count |29 |Sensors within threshold; ok
date and time stamp |n13 |Sensor count |28 |Sensors within threshold; ok
date and time stamp |n12 |Sensor count |27 |Sensors within threshold; ok
