How to configure the XSCF for Nagios Monitoring Sun (Fujitsu) MX000 series servers

• Configuration Environment Description

192.168.3.80-XSCF address 192.168.2.80-solaris operating system IP address (Nagios client) 192.168.2.120-nagios server-side Check_ xscf.pl-checks the execution script of the XSCF and places it on the Nagios client. check_xscf.cfg-checks the XSCF configuration file, which is used primarily to set the temperature and voltage thresholds on the Nagios client. Script: Http://exchange.nagios.org/directory/Plugins/Uncategorized/Plugin-to-check-Sun%27s-XSCF-%28local-service%29 /details script Execution: The Nagios server executes the XSCF command by calling the check_xscf.pl script on the Nagios client through Check_nrpe.

• Generate RSA key for user Nagios on Nagios client

• Configuring the Nagios client
