7signal Sapphire Carat Carat User Guide Release 3.1
24.2 Adding Nagios Plug-ins To Sapphire Software
The prerequisite is that client-side tools of Nagios have been installed on the host running
7signal Sapphire software. The protocol being used is NRPE. There is no SSH support
concurrently.
24.2.1 Install NRPE daemon
Use online install with yum:
# yum install nrpe
24.2.2 Install toolset ‘Nagios plugins’
Use online install with yum:
# yum install nagios-plugins-nrpe
NOTE: the following installers shall open port tcp/5666 for Nagios traffic in the
firewall settings.Install Sapphire plugin
There folders named Nagios_support on both Carat and Sonar delivery disks. They contain the
following files
7signal-Nagios-plugin-<version-info>-for-Carat-installer.bin
7signal-Nagios-plugin-<version-info>-for-Loupe-installer.bin
7signal-Nagios-plugin-<version-info>-for-Sonar-installer.bin
The files are executable and totally self-contained. By running each of the file makes the
respective Sapphire Nagios plugin available. The process includes configuration file creation,
updates and firewall settings.
Silent install mode (option -s) uses 7signal defaults for all parameters. If this option is not used,
all parameters are inquired interactively with the default setting visible.
By default, the plugin installations end up in /opt/7signal/nagios folder. However, the
installation makes the plugins available and after this the process and operations are
completely transparent to the Carat user.
24.3 Verifying Nagios Installation
Complete and operational install is achieved if Nagios GUI shows
check_carat_server
check_sonar_server
check_loupe_server
as options for monitoring for the hosts running 7signal Sapphire software.
24.4 Removing Nagios plugins
The installation directory contains uninstall_nagios.sh that removes Sapphire related
plugin files. The NRPE daemon stays untouched and its configuration is cleaned only for
Sapphire plugins thus NRPE and other Nagios operations remain untouched.
