LCG-FR / SA1-FR Monitoring NagiosWithQuattor
Sommaire
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. 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' }; ############ #Fonctionnalite UI utile pour nagios service grille variable VOS ?= list('grif','dteam'); include { 'machine-types/ui' }; ############ #include Nagios server ############################## ##What resources are monitored variable SITES = list('dapnia'); include { 'config/nodes_properties' }; ############################## ###Configuration, setting variables variable NAGIOS_NCG_CONFIG = true; variable NAGIOS_NOTIFICATIONS_ENABLED = false; variable NAGIOS_NODES_PROPERTIES = NODES_PROPS; variable NAGIOS_DEFAULT_ADMIN_NAME = "dapnia"; variable NAGIOS_IGNORED_NODES = list("node09.datagrid.cea.fr","node19.datagrid.cea.fr","node22.datagrid.cea.fr"); variable NAGIOS_MONITORED_HOSTGROUPS = list("WN","NFS","SEDPM","SE_DISK","SITE_BDII","MON","LFC","CE","CE-MPI","VOBOX","UI","WMS"); variable NAGIOS_ADMIN_CONTACTS= nlist( "tuto1" ,"tuto1@org.fr", "tuto2" ,"tuto2@org.fr", ); variable NAGIOS_HTPASSWD_LOGIN ?= "grif"; variable NAGIOS_HTPASSWD_PASS ?= 'xxxxxx'; ############################## ###Functions used to configure services and hosts include { 'monitoring/nagios3/server/functions' }; ############################## ###Services configuration variable TMP_SERVICE=nlist( "use"," generic-service", "host_name"," node07.datagrid.cea.fr", "service_description"," Workers ssh_known_hosts", "contact_groups"," admins", "check_command"," check_nrpe_long!check_ssh_known_hosts!60", "normal_check_interval"," 60 ; check every hour", "max_check_attempts"," 1", ); variable NAGIOS_SERVICES=nagios_add_service(TMP_SERVICE); variable NAGIOS_USER_DEFINED_HOST_DEPENDENCIES=nagios_add_host_service_dependency\ ("node07.datagrid.cea.fr","nrpe daemon","node07.datagrid.cea.fr","Workers ssh_known_hosts"); include { 'monitoring/nagios3/server/config' }; ### # # software repositories (should be last) # include { 'rpms/siteupdates' }; include { PKG_REPOSITORY_CONFIG };
What is monitored
hosts present in config/nodes_properties.tpl will be monitored, you can tune this with the variable:
NAGIOS_IGNORED_NODES
NAGIOS_MONITORED_HOSTGROUPS
see the profile above.
