Hop, j’ai trouvé ça : http://labs.consol.de/nagios/check_oracle_health/ repéré sur exchange.nagios.org.
Y’a aussi le pendant pour MySQL, MSSQL etc. A voir à l’occasion.

Ca permet de contrôler depuis Nagios tout un tas de choses dans une instance Oracle : hit ratio, nb de sessions, vitesse de remplissage des redo logs, espace libre des tablespaces etc.
Avec ça et Oracle ToolBox que je décris là, y’a de quoi surveiller et optimiser.

L’installation de ce plug-in est assez simple. Le plus dur est d’avoir un environnement PERL/Oracle fonctionnel. Je le décris dans un précédent article, car ça bug un peu.

Installation

Ensuite, il faut simplement récupérer les sources (actuellement cette version), lire le fichier « INSTALL », ce qui revient à taper un classique configure/make/make check/make install et vérifier qu’on obtient bien le binaire dans /usr/local/nagios/libexec/.
Si vous devez créer un utilisateur Oracle dédié pour analyser ces indicateurs, la doc dit de lui donner ces permissions :

serveur:~# sqlplus sys/manager_que_t_as_pas_change_gros_malin@MABASE as sysdba
CREATE user nagios IDENTIFIED BY super_motdepasse;
GRANT CREATE session TO nagios;
GRANT SELECT any dictionary TO nagios;
GRANT SELECT ON V_$SYSSTAT TO nagios;
GRANT SELECT ON V_$INSTANCE TO nagios;
GRANT SELECT ON V_$LOG TO nagios;
GRANT SELECT ON SYS.DBA_DATA_FILES TO nagios;
GRANT SELECT ON SYS.DBA_FREE_SPACE TO nagios;

Test en ligne de commande

Enfin, on l’essaye avec :
/usr/local/nagios/libexec/check_oracle_health
Par exemple :

serveur:~#/usr/local/nagios/libexec/check_oracle_health  --connect nagios/super_motdepasse@MABASE --mode sga-library-cache-hit-ratio
CRITICAL - SGA library cache hit ratio 53.51% | sga_library_cache_hit_ratio=53.51%;98:;95:

Houuuuu, la baffe !

Intégration dans Nagios

Et pour intégrer tout ça dans Nagios, il suffit de jouer avec NRPE en ajoutant les petites commandes qui vont bien dans le fichier /etc/nagios/nrpe_local.cfg. J’en parle déjà ici. Et comme je suis sympa, j’en donne un long exemple en fin de cet article.

Une fois lancé depuis Nagios, alors qu’en utilisateur nagios et ligne de commande, ça marchait bien, je me suis récupéré l’erreur ORA-24327 « need explicit attach before authenticating a user » en sortie de NRPE…
Il manquait des variables d’environnement à passer à l’utilisateur nagios pour le daemon NRPE. Je n’ai rien trouvé plus propre que de modifier le script de lancement du service… (si vous avez mieux, dites moi) :

serveur_nrpe:~# head -30 /etc/init.d/nagios-nrpe-server
#! /bin/sh
#

### BEGIN INIT INFO
# Provides:          nagios-nrpe-server

### END INIT INFO


PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/sbin/nrpe
NAME=nagios-nrpe
DESC=nagios-nrpe
CONFIG=/etc/nagios/nrpe.cfg

### JACQUES pour ORACLE/Nagios check_oracle_health
export ORACLE_HOME=/usr/lib/oracle/11.1/client
export PATH=$PATH:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
###

test -x $DAEMON || exit 0

blablablababla...

Résultat

A la fin, ouaaa, ça donne ça :

Yapuka corriger la palanquée de problèmes. Où est mon DBA ? ah, y’en a pas, ça promet. Allez, on ressort « Oracle for dummies ».

Conf NRPE de tous les tests

Comme je suis sympa, je donne un bout de fichier de conf NRPE au cas où. J’ai simplement fait cracher tous les « modes » (contrôles) possibles en scriptant, histoire de générer ça facilement.

Remarques

J’ai fait le bourrin : un « service Nagios » = un « appel NRPE » = un « lancement de check_oracle_health ». On doit pouvoir fignoler avec des paramètres et le « check_nrpe » normal plutôt que le « 1arg »-ument.

Enfin, vous pouvez détailler chaque test pour les problèmes de verrous, events etc. La liste est méga longue. Vous pourrez facilement scripter pour obtenir la liste de tous les test si vous êtes un bon gros psychopathe.
A base de :

check_oracle_health --blabla -mode list-events | awk ...

et idem pour les sysstats, enqueues, latches etc.
Attention, dans les 3000 tests (de mémoire) et des fichiers de conf Nagios de 10 km de long. C’est passablement crétin de tout mettre d’un coup (bon OK, je l’ai fait quand même, histoire de voir ;)) car le serveur Nagios accuse un peu le coup.
Je crois de plus que les tests génériques, genre check_oracle_health --mode event-waits sortent en premier les erreur critiques les plus graves. Pas la peine de descendre dans un détail sans fin de check_oracle_health --blabla --mode event-waits --name 687721825 par exemple, ou encore /usr/local/nagios/libexec/check_oracle_health --connect bla/bla@BLA --mode enqueue-waiting --name XR.

Voilà, vous devriez pouvoir sortir un reporting de votre base en 17 tomes, de quoi assomer n’importe quel patron, emmerder un DBA et vous laisser du temps libre.
