Installation d'une NOGIOS box pour le ROC France

1) Installation de base :

a. Machine installée par les sysadmin du CC : OS + VOBOX + certificat + pas dans les NIS

b. Accessible via gsissh (port 1975)

2) Action faite au préalable :

a. Faire la demande pour que la machine soit autorisée à récupérer les SAM tests : https://gus.fzk.de/ws/ticket_info.php?ticket=55132

b. Autoriser la nagios box à récupérer les proxy en mode « retrieval », et stocker un proxy depuis une UI récuperable par la nagiosBOX voir Annexe0


c. Certificat utilisé pour :

i. Access to GOCDB PI for ROCS GOCDB PI level 2 required

ii. Recuperation de proxy pour les sondes locales

d. s'inscrire dans la mailing liste: regional-nagios-admins@cern.ch (très réactive)

3) Installation de Nagios

Reference : https://twiki.cern.ch/twiki/bin/view/EGEE/GridMonitoringNcgYaim

Installation des packages via yum, Ajout des repos suivant

a.	mirrors-rpmforge (rpm rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm)
b.	rpmforge-testing.repo
c.	rpmforge.repo
d.	glite-UI.repo
e.	sa1-centos5-release.repo (rpm:  sa1-release-2-1.el5.noarch.rpm)
f.	glite-BDII.repo

Problèmes de dépendances rencontrées si besoin se référer Annexe1 (mais j’avais dû oublier de faire un : yum install egee-NAGIOS)


Installation subversion

Certain fichier de config sont a recuperer via svn au CERN: 

yum install subversion
svn co http://svnweb.cern.ch/guest/sam/trunk/roc-config



cp /usr/lib/perl5/vendor_perl/5.8.5/NCG/LocalMetrics/Hash.pm /usr/lib/perl5/vendor_perl/5.8.5/NCG/LocalMetrics/Hash.pm.orig
cp roc-config/Hash.pm_55_ALL_CRIT /usr/lib/perl5/vendor_perl/5.8.5/NCG/LocalMetrics/Hash.pm

Mysql

1. Installer la dernière version de Mysql (server + client) ;

2. configurer le mot de passe admin se référer Annexe2a ;

3. Configurer les users utiles à la nagios Box se référer Annexe2b ;

Configuration via yaim et NCG (en 2 fois)

1. Remplir /etc/ncg/ncg.localdb avec la liste des sites se referer Annexe3


2. Remplir le /opt/glite/yaim/site-info.def voir Annexe4 ;

3. groupadd nagios

4. modif des uids/gids : /opt/glite/yaim/examples/edgusers.conf Annexe5


5. lancement de la configuration automatique via yaim (All On One Box) : 

	/opt/glite/yaim/bin/yaim -s /opt/glite/yaim/site-info.def -c -n glite-UI -n glite-NAGIOS

6. lancement de la configuration via NCG (All On One Box) : 

/usr/sbin/ncg.pl

.....MODIFICATION importante:: voir: https://twiki.cern.ch/twiki/bin/view/EGEE/ValidateROCNagios La partie:

  1. Configure manually /etc/ncg/ncg.conf (Template can be found here: ncg.conf.template: )

- Switch off automatic generation of ncg.conf by YAIM (NAGIOS_NCG_ENABLE_CONFIG"="false") - Take ncg.conf.template and copy it to /etc/ncg/ncg.conf 

    - Set $ROC_NAME$
    - Set $YOUR_MYPROXY_SERVER$ (e.g. myproxy-fts.cern.ch)
    - Set $MYPROXY_NAME$ (e.g.: NagiosRetrieve-sam-ap-roc.cern.ch)
    - Set $NAGIOS_ROLE$ (e.g.: ngi, roc)
  1. Take Hash.pm file that we are currently using at the CERN ROC Nagios boxes. In this file, we have removed the metrics that do not belong to the SAM_Critical profile, so only the metrics defined at ROC_SAM_critical are configured, and not relevant services like SRMv1 are commented out. The file is located under /usr/lib/perl5/vendor_perl/5.8.5/NCG/LocalMetrics/Hash.pm

Pour éviter d'avoir des sondes inappropriés.

Tuning the configuration

1. Verifier dans /etc/sysconfig/nagios: 

LD_LIBRARY_PATH=/opt/classads/lib64:/opt/glite/lib64:/opt/globus/lib:/opt/c-ares/lib:/opt/classads/lib64

2. Desactiver les notifications, dans les fichiers de conf: 

a.      /etc/nagios/nagios.cfg, désactiver les notifications:enable_notifications=0 ;log_notifications=0
b.	 /etc/nagios/wlcg.d/host.templates.cfg
c.	 /etc/nagios/wlcg.d/service.templates.cfg

4. N’autoriser que les dteam/France à visualiser notre interface nagios : modifier le fichier : 

/etc/voms2htpasswd.conf, avec : vomss://voms.cern.ch:8443/voms/dteam?/dteam/france

Plus utile site le site-info.def est défini correctement: 

VO_DTEAM_VOMS_SERVERS='vomss://voms.cern.ch:8443/voms/dteam?/dteam/france'

ActiveMQ

/usr/sbin/msg-to-queue --prefix /queue/grid.probe.metricOutput.EGEE.a635834332381123c8b296d02b682f8f --broker-uri stomp://prod-grid-msg.cern.ch:6163

[root@cclcgvmli03 cron.hourly]# cat check_msg-to-queue.sh

Verifier les messages: 

/usr/libexec/grid-monitoring/plugins/nagios/recv_from_queue -v

faire une update de perl-GridMon 

The problem here is in the message handler 
(/usr/lib/perl5/vendor_perl/5.8.8/GridMon/MsgHandler/MetricOutput.pm). 
Probe on WN reports hostname localhost.localdomain and serviceURI CE 
hostname. In the previous version message handler first checked hostname 
value and then serviceURI. That is the reason why Christine is seeing 
results for localhost.localdomain. However, we fixed this and the latest 
version (1.0.34) parses messages correctly.

yum update perl-GridMon

 

Systeme d'information

La nagios Box doit etre enregistré dans la GOCDB et publié dans le site-BDII: 

ldapsearch -x -H ldap://ccnagboxli01.in2p3.fr:2170 -b 'Mds-vo-name=resource,o=Grid'

validation

https://twiki.cern.ch/twiki/bin/view/EGEE/ValidateROCNagios

now you should publish your Nagios in your Site BDII And we should declare the node in the GOCDB: Regional-NAGIOS ou National-Nagios, a determiner


liste des sondes a valider: d'après: https://twiki.cern.ch/twiki/bin/view/LCG/SAMCriticalTestsForCODs

Annexe0

Sur le myproxyserver, il faut que le nagios server soit "trusted retriever" et "authorized retrievers": 

[cleroy@grid08 ~]$ grep cclcgvmli03 /opt/glite/etc/myproxy-server.conf
trusted_retrievers /O=GRID-FR/C=FR/O=CNRS/OU=CC-LYON/CN=cclcgvmli03.in2p3.fr
authorized_retrievers /O=GRID-FR/C=FR/O=CNRS/OU=CC-LYON/CN=cclcgvmli03.in2p3.fr

 

Sur une UI: 

voms-proxy-init -voms ops:/ops/Role=lcgadmin
myproxy-init -c 336 -k nagios_roc_fr2-ops -s myproxy.grif.fr -l nagios  -x -Z "/O=GRID-FR/C=FR/O=CNRS/OU=CC-LYON/CN=cclcgvmli03.in2p3.fr"

mysqld_safe --skip-grant-tables &
[root@cclcgvmli03 ~]# mysql -u root 
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';

b)creation des users pour le nagios regional: 

[root@cclcgvmli03 ~]# mysql -u root -p
mysql> GRANT SELECT, INSERT, UPDATE, DELETE ON nagios.* TO 'ndouser'@'localhost' IDENTIFIED by 'ROCfr2009';
mysql> GRANT SELECT, INSERT, UPDATE, DELETE ON atp.* TO 'atpuser'@'localhost' IDENTIFIED by 'ROCfr2009';
