Installing Nagios with 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.

Repository Used

Sensors are provided for many of the plug-ins from: -the SA1 repository: http://www.sysadmin.hep.ac.uk/rpms/grid-services/RPMS.monitoring/

-RPMs for nagios and nagios-plugins (+dépendances) are compiled for each supported OS, and are put in the repository « updates » on quattorsrv.lal.in2p3.fr. Ex. : http://quattor.web.lal.in2p3.fr/packages/os/sl440-i386/updates/

-Plugins « nagios-grid-plugins » are in noarch RPM in the repository « nagios » Ex. : http://quattor.web.lal.in2p3.fr/packages/nagios/

Server Template

An example Nagios server template is here :

https://trac.lal.in2p3.fr/LCGQWG/browser/templates/trunk/clusters/example-3.1/profiles/nagios3-server.example.org.tpl

This machine should be a UI to monitor grid services.

Who is monitored

hosts from site (variable SITES) and present in config/’sitename’_nodes_properties.tpl will be monitored

Template example for host declaration are in LCGQWG: https://trac.lal.in2p3.fr/LCGQWG/browser/templates/trunk/sites/example/site/config

You can tune this with:

NAGIOS_IGNORED_NODES

NAGIOS_MONITORED_HOSTGROUPS


see the profile above.

What is monitored

Proxy management

Need to have a valid certificate for local grid probe. 2 mechanisms are possible: Renewal and Retrieval. In cfg/standard/monitoring/nagios3/server/config.tpl

include { if(NAGIOS_NCG_CONFIG && NAGIOS_MODE_PROXY_RENEW) 'monitoring/nagios3/server/vobox'};
include { if(NAGIOS_NCG_CONFIG && NAGIOS_MODE_PROXY_RETRIEVE) 'monitoring/nagios3/server/proxy_retrieval'};

Les variables associées:

NAGIOS_MODE_PROXY_RENEW
NAGIOS_RENEW_PROXY 
NAGIOS_OUTPUT_PROXY
NAGIOS_MODE_PROXY_RETRIEVE
NAGIOS_MYPROXY_NAME 
MYPROXY_SERVER
NAGIOS_VONAME_PROXY

Installation Exemple

With Quattor

server profile creation look at the profile above.

svn add cfg/clusters/your-3.1/profiles/profile_node58.tpl

Modify your list of machines:

vi ./cfg/sites/your/site/config/your_nodes_properties.tpl

create your hardware template

svn cp ./cfg/sites/your/hardware/virtual_machine_3.tpl ./cfg/sites/your/hardware/virtual_machine_13.tpl


Comit your change:

svn ci -m 'adding serveur nagios'


on the nagios server

vi /var/log/spma.log
vi /var/log/ncm-cdispd.log
/etc/init.d/nagios status
/etc/init.d/nagios start


Verifier le certificat serveur
