Nagios directory, file description, and service configuration

Service-Side Directory Description:

Bin	Nagios executable directory Nagios nagiostats Nrpe
etc	The Nagios configuration file is in the same directory nagios.cfg contains other configuration files Htpasswd.users Password file nrpe.cfg Client configuration file
Sbin	The directory where the Nagios CGI files are located, that is, the files required to execute the external command histogram.cgi showlog.cgi statuswrl.cgi
Share	The directory where the Nagios Web page file resides
Libexec	Nagios external plug-in directory Check_ifstatus Check_nrpe
Var	The directory where Nagios log files, lock, and other files are located nagios.log
Var/archives	Nagios Log Auto Archive directory
Var/rw	The directory used to store external command files

Location: etc/objects/

Commands.cfg stores the Nagios command-related configuration (optionally specifying the commands directory), where the command is not a system command. Instead, it implements a file that associates the commands in Nagios with the plug-in commands in the Linux system.

SERVICES.CFG store specific monitored service-related configuration content (more than hundred units can specify the services directory, default none)

hosts.cfg storage of specific monitored host-related configuration (more than hundred units can specify the hosts directory, default does not exist)

CONTACTS.CFG Store Alarm Contact-related configuration files

TIMEPERIODS.CFG Storage Alarm cycle time and other related configuration

templates.cfg~ template configuration file, template exists for the convenience of configuration service configuration, similar to shell functions.

Introduction to server-side master profiles and configuration preparation

File generation:

To etc/objects using localhost.cfg to generate hosts.cfg files

head-51 localhost.cfg >hosts.cfg

Chown-r Nagios.nagios hosts.cfg

Create a Serveses.cfg file

Touch services.cfg

Chown-r Nagios.nagios services.cfg

Define Host{

}

#逗号, separating the host
