LCG-FR / SA1-FR Monitoring NagiosWithQuattor

Installation de Nagios par Quattor

Nagios configuration requires both a set of client templates for commands to be run on clients by the Nagios Remote Plug-in Executor (NRPE) and a set of server templates configuring contacts for alarms, hosts to be monitored, services (AKA sensors) and so on.

Configuring the Nagios server

The configuration of a Nagios server is done in a set of standard templates, in the 'monitoring/nagios3' namespace. Sensors are provided for many of the plug-ins from the SA1 repository: http://www.sysadmin.hep.ac.uk/rpms/grid-services/RPMS.monitoring/

An example Nagios server template is included in the QWG distribution !A FAIRE! :

object template profile_node58;

include { 'rpms/kernelupdates' }; # this includes kernel updates, no matter the OS version
variable AII_KS_SRV = "192.54.208.182";
variable AII_ACK_SRV = AII_KS_SRV;
variable NFS_AUTOFS = true;
include { 'site/firewall/nagios_server' };
