PowerShell/SQL–Script générant un .csv contenant le résultat d’une requête

Introduction

Le script suivant permet :

  • de récupérer le résultat d’une requête SQL dans un fichier .csv,
  • de renseigner les actions réalisées dans l’EventViewer,
  • de retourner un code d’erreur (0 ou 1) suite à l’exécution du script.

Prérequis

  • Powershell
  • SQL

Présentation du script

Variables :

[string] $server = "localhost" : Serveur SQL
[string] $database = "base" : Base SQL
[string] $query = "SELCT * FROM Table" : Requête ou procédure stockée
[string] $extractFilePath = "C:\test.csv" : Emplacemnt de génération du fichier .csv
[string] $delimiter = ";" : Délimiteur à utiliser pour la génération du fichier .csv
[int] $skipline = 1 : Nombre de ligne à tronquer (utile si l’on souhaite retirer la ligne d’entête.

SCOM - Script de Fermeture des alertes liées a des monitors en état Healthy

Ci-dessous une nouvelle version d'un script de fermeture des alertes liées a des monitors en état Healthy. En effet meme si le cas contraire est plus fréquent (alerte fermée alors que le monitor est encore en état Warning ou Critical), il se peut que l'on doivent fermer les alertes de monitors en état Healthy.

Le script affiche clairement la sortie des alertes a traiter et log cette sortie dans l'eventlog.

[Powershell] Excel ne s'enregistre pas via le Planificateur de tâches

Lancer un script Powershell via le planificateur de tâches ne pose aucun problème, en revanche si ce dernier souhaite utiliser Excel (par l'intermédiaire de la commande "new-object -comobject excel.application") on peut rencontrer un problème.

Je dis "on peut" car cela fonctionne si l'on a pas coché la case "Run Whether user is logged on or not", en revanche si cette dernière est cochée, Excel ne sera pas en mesure d'enregistrer le fichier.

Pourquoi ?

Par défaut l'application Excel s'exécute avec le compte "Utilisateur exécutant (The Launching User)", mais si j'utilise une tâche planifiée qui ne nécessite pas que je sois connecté Excel ne parvient pas a déterminer qui fait appel à lui.

Que Faire ?

Simplement en déclarant qui  exécute l'application Excel via la MMC -> Services des composants.

Je vous renvoie au point 2 (Gestion de l'Excel distant) de mon précédent article : [Powershell] Ecrire dans un Excel distant.

Supervision – SQL – 3 scripts pour la supervision de Always On

 

Dans le cadre d’un portage de règle de supervision, les trois scripts ci-dessous ont été crées pour remonter l’état de:

En pratique ils utilisent a peu près la même requête SQL. Ils contiennent des éléments propre a l’api scom mais peuvent bien sur être adapté pour être utilisé indépendamment.
