The HP XC System Software uses the Nagios monitoring application to gather and display environment data. The HP XC System Software provides plug-ins that monitor each node's environment data, such as temperature and fan speed, which can be indicators of possible node failure.
To display environment data, first select the Service Problems menu item in the left frame of the Nagios main window, shown in Figure 6-3, to open the Service Status for All Hosts window.
For additional information about the Nagios Service Status for All Hosts window and related topics, select Documentation on the Nagios menu, or visit the Nagios Web site:
http://www.nagios.org .
You can also use the shownode metrics sensors command to display environmental data. See “Displaying System Sensors from the Command Line” for more information.
Depending on the platform, there may be tools that allow you to collect information specific to the platform. Typically, this same information is collected and available in the HP XC database from the shownode metrics sensors command. For example, systems that support the iLO management interface include the hpasm package. You can use the /sbin/hplog utility to display the following environment data:
In addition, most hpasm errors are logged to the syslog system logger. For more information, see hpasm(4) and hplog(8).
