L'idée du script ci-dessous est de proposer une forme d'inventaire des applications couvertes par une infra SCOM, en utilisant une liste, a maintenir, des principales classes d'objets tel que 'Active Directory Domain Controller Computer Role' ou encore 'IIS Server Role'.
Il est donc necessaire de maintenir un minimum dans le temps, le contenu de $ClassList, et la correspondance faites entre les pattern de nom de classes et les application correspondantes.

A l’instar de la plupart des outils de supervision, Zabbix propose un système de mise en maintenance de la supervision.
Pour configurer une nouvelle maintenance, Aller dans le menu Configuration / Maintenance:
Cliquer Create Maintenance Period
Renseigner le nom de la période.
Intéressant, le choix est donné de collecter ou non les données.
Attention: les champs de date Active Since et Active Till ne représente pas la période de maintenance elle même mais le temps au sein duquel nous allons créer une ou plusieurs périodes dans l’onglet correspondant (Periods)
Dans l’exemple ci-dessous on positionne une plage de temps d’un an.
Aller dans l’onglet Periods. Cliquer Add
4 modes sont disponibles: One Time Only, Daily, Weekly et Monthly.
Dans l’onglet Hosts and groups, selectionner le/les hosts ou le/les host groups
Une fois la période crée, elle apparait en état Approaching lorsque la date Active Since approche.
Lorsque les hosts concernés sont effectivement en période de maintenance, l’icone 
apparait a coté, jusqu’a la fin de la période.
Dans cet exemple, dans un an, la règle de maintenance passera en mode Expired.
Le script ci-dessous affiche tout les hosts avec leur status et les templates associés

Zabbix propose plusieurs manière de superviser des URL. L’exemple ci-dessous propose d’utiliser un ‘Web Scenario’ pour la supervision d’une URL simple (ici www.google.fr).
on commence par créer un template vide qui contiendra la configuration:
NB: Le nom du Host group associé est arbitraire.
Cliquer Add.
Le template vide est crée.
Cliquer “Create Web Scenario”
Name: Check Google
Agent: On positionne Zabbix. ce champs permet de selectionner plusieurs type de client http/navigateur.
Cliquer Steps.
Dans la zone Steps, cliquer sur Add.
name: Google base page
URL: http://www.google.fr
Required Status codes: 200
Cliquer Add
Le Web scenario est crée.
On applique (Link) le template au host devant effectuer le check de supervision.
Apres quelques minutes les données remonte dans la liste des “Latest data” du host concerné. on voit ici que le code HTTP renvoyé est bien 200 (OK)
On crée a présent un trigger (alerte) en charge declencher une alerte sur le cas ou le code HTTP serait different de 200.
Dans les propriétés du template, cliquer Triggers
cliquer en haut a droite Create Trigger
Name: Google Site KO
Clquer sur Add a coté de la zone Expression pour construire la condition de declenchement.
Cliquer sur Select pour aller rechercher l’item crée precedemment.
Selectionner “Response code for step “Google base page”…”
Laisser selectionné la fonction “last()”.
Result: <> 200
cliquer Insert.
A titre d’indication ajouter le nom de l’url surveillée dans le champ URL.
Cliquer Add.
Le trigger est maintenant actif.
Le script suivant est une nouvelle version d'un script récemment proposé. Ont été rajouté le choix entre suppression et mode maintenance (on verifie aussi que la machine est déjà en mode maintenance)

Le script ci-dessous propose le scenario ou l'on doit automatiser la suppression d'un agent de la console (pas une desinstallation) en fonction de la valeur d'une ou plusieurs propriétés de l'instance d'une classe pour ce/ces agents.
Ceci peut permettre par exemple dans la cas de la présence d'une classe étendue (avec vos propres propriétés issues par exemple d'un outil tiers) de decommissionner un ou plusieurs agents automatiquement, selon la valeur de ces propriétés (Dans l'exemple inscrit par defaut dans les paramètres, on cherche la valeur 'Useless' ou 'Deprecated' de la propriété 'Usage' de la classe 'MyClass')
