# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

SCOM - Script - Exemple d'inventaire avec les classes "Principales".

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.

Zabbix – Principe des périodes de maintenance


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:

image


Cliquer Create Maintenance Period

image


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.

image


Aller dans l’onglet Periods. Cliquer Add

image


4 modes sont disponibles: One Time Only, Daily, Weekly et Monthly.

imageimageimageimageimage


Dans l’onglet Hosts and groups, selectionner le/les hosts ou le/les host groups

image


Une fois la période crée, elle apparait en état Approaching lorsque la date Active Since approche.

image


Lorsque les hosts concernés sont effectivement en période de maintenance, l’icone image apparait a coté, jusqu’a la fin de la période.


image

image


Dans cet exemple, dans un an, la règle de maintenance passera en mode Expired.

Zabbix – Supervision basique d’une URL


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:

image


image


image

NB: Le nom du Host group associé est arbitraire.

Cliquer Add.

image

Le template vide est crée.


image

Cliquer “Create Web Scenario”


image

Name: Check Google

Agent: On positionne Zabbix. ce champs permet de selectionner plusieurs type de client http/navigateur.

Cliquer Steps.


image

Dans la zone Steps, cliquer sur Add.


image

name: Google base page

URL: http://www.google.fr

Required Status codes: 200


image

image

Cliquer Add

image

Le Web scenario est crée.


image

On applique (Link) le template au host devant effectuer le check de supervision.


image


image

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.

image

image

Dans les propriétés du template, cliquer Triggers


image

cliquer en haut a droite Create Trigger


image

Name: Google Site KO

Clquer sur Add a coté de la zone Expression pour construire la condition de declenchement.


image

Cliquer sur Select pour aller rechercher l’item crée precedemment.


image

Selectionner “Response code for step “Google base page”…”


image

Laisser selectionné la fonction “last()”.

Result: <> 200

cliquer Insert.


image

A titre d’indication ajouter le nom de l’url surveillée dans le champ URL.

Cliquer Add.


image

Le trigger est maintenant actif.

SCOM - Script - Supprimer un agent de la console en fonction de la valeur d'une ou plusieurs propriété d'une classe

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')
