4.4 Task 4: Use Nagios to View System Health
Nagios is a system and network health monitoring application. It watches hosts and services and alerts
you when problems occur or are resolved. HP recommends that you start up Nagios now to view the
network and ensure it is up and running (that is, all components are in the green state).
Enter the following URL in the browser to access the Nagios main window:
https://fully_qualified_HP_XC_hostname/nagios
If the hardware configuration contains tens of nodes, the Service Detail view provides a good overview
of the system. It lists the Nagios hosts and shows their status.
The Service Problems view is more useful for hardware configurations with hundreds or thousands
of nodes. It provides a practical overview of the system.
See the HP XC System Software Administration Guide if you need more information about how to use Nagios.
4.5 Task 5: Take a Snapshot of the Database
After you run the OVP to verify the successful installation and configuration of the system, HP recommends
that you take a snapshot of the configuration and management database to create a baseline version. A
baseline copy of the database can be useful if you have to restore the database to its original state.
Enter the following command to back up the configuration and management database to a file. If you do
not specify a directory, the default location for the backup file is in the /var/hptc/database directory.
Consider adding a date and time stamp to the file name to determine at a glance when the backup file was
created.
# managedb backup your_filename
Depending upon your corporate security policy for managing system and database backups, consider
storing the database backup file on a remote system as an additional precaution.
The HP XC System Software Administration Guide provides information about basic database management
commands. For more information about managing the configuration and management database, consult
the MySQL Reference Manual, which is available at the following Web site:
http://dev.mysql.com/
4.6 Task 6: Create a Baseline Report of the System Configuration
The sys_check utility is a data collection tool that is used to diagnose system errors and problems. Use
the sys_check utility now to create a baseline report of the system configuration (software and hardware).
The sys_check utility collects configuration data only for the node on which it is run unless you set and
export the SYS_CHECK_SYSWIDE variable, which collects configuration data for all nodes in the HP XC
system.
Use the following commands to invoke the sys_check utility in its simplest form:
# export SYS_CHECK_SYSWIDE=1
# sys_check > /tmp/filename.html
By default, the sys_check utility creates the report in HTML format, but there is an option to create a
text version. You can redirect the output of the sys_check report to the directory and file name of your
choice.
For more information about this utility and its options, see the HP XC System Software Administration Guide
and sys_check(8) .
4.7 You Are Done
Your HP XC system is now fully installed, configured, and operational.
