Introduction
La mesure de la durée de fonctionnement d’un appareil est cruciale dans le monde informatique. Savoir combien de temps les systèmes ont fonctionné sans redémarrage peut aider à maintenir des performances optimales et à résoudre les problèmes. Un script PowerShell capable de calculer et de signaler avec précision la durée de fonctionnement des appareils Windows est un outil précieux pour les professionnels de l’informatique.
Contexte
Le script en question est conçu pour surveiller et signaler le pourcentage de disponibilité d’un périphérique Windows, y compris les détails des événements de démarrage. C’est particulièrement important pour les professionnels de l’informatique et les fournisseurs de services gérés (MSP), car cela permet une maintenance proactive et une réponse rapide aux problèmes du système. La capacité à déterminer avec précision la disponibilité des appareils sur une période donnée est essentielle dans divers scénarios, qu’il s’agisse de contrôles de maintenance de routine ou de l’identification de défaillances potentielles du système.

.SYNOPSIS
Get the Uptime percentage of a Windows device and show a list of boot events.
.DESCRIPTION
Get the Uptime percentage of a Windows device and show a list of boot events.
Unexpected Shutdowns can skew results slightly.
Duration in results is in days.

Description détaillée
Le script fonctionne en plusieurs étapes :
- Initialisation des paramètres : Il accepte des paramètres tels que le nombre de jours, des dates de début et de fin spécifiques et des noms de champs personnalisés pour l’édition.
- Contrôle de l’environnement : Il ajuste les paramètres en fonction des variables d’environnement si elles sont disponibles.
- Validation : Veille à ce que les paramètres d’entrée soient logiquement cohérents et valides.
- Analyse du journal des événements : Le script récupère les journaux d’événements du système pour identifier les événements de démarrage et d’arrêt.
- Calcul de la durée de fonctionnement : Il calcule la durée de fonctionnement en analysant la durée entre les événements de démarrage et d’arrêt.
- Génération de rapports : Génère un rapport détaillé comprenant le pourcentage de durée de fonctionnement, la durée totale et les entrées de démarrage individuelles.
- Sortie des champs personnalisés : Il est possible d’éditer les résultats dans les champs personnalisés spécifiés pour l’intégration avec d’autres outils tels que NinjaOne.
Cas d’utilisation potentiels
Prenons l’exemple d’un responsable informatique qui supervise un réseau d’appareils Windows dans un environnement d’entreprise. Ils utilisent ce script pour contrôler la fiabilité du système, en particulier après le déploiement d’une mise à jour importante. En examinant les statistiques relatives à la durée de fonctionnement, ils peuvent traiter de manière proactive tout problème d’instabilité ou identifier les appareils qui nécessitent une maintenance.
Comparaisons
Traditionnellement, la durée de fonctionnement est souvent vérifié manuellement via le gestionnaire des tâches ou les outils d’information du système sous Windows. Toutefois, ce script automatise le processus, fournit des informations plus détaillées et permet une analyse historique sur des périodes personnalisées, ce qui le rend plus efficace et plus complet.
FAQ
Q1 : Ce script peut-il rendre compte des systèmes distants ?
A1 : Oui, s’il est exécuté dans un environnement réseau avec les privilèges d’accès appropriés.
Q2 : Est-il possible de programmer l’exécution automatique de ce script ?
A2 : Oui, le script peut être programmé à l’aide du planificateur de tâches de Windows ou d’outils similaires.
Q3 : Quelle est la précision de l’estimation de l’arrêt imprévu ?
A3 : Il fournit une estimation basée sur le dernier journal d’événements connu, qui n’est pas toujours exacte à 100 %, mais qui offre une approximation proche.
Implications
Comprendre la durée de fonctionnement des appareils est essentiel pour la sécurité et l’efficacité de l’informatique. Une durée de fonctionnement continu sur de longues périodes peut indiquer que des mises à jour ou des correctifs critiques ont été oubliés, ce qui constitue un risque pour la sécurité. À l’inverse, des redémarrages fréquents peuvent être le signe d’une instabilité sous-jacente du système.
Recommandations
Les meilleures pratiques comprennent la programmation régulière du script pour une surveillance cohérente, la personnalisation des champs de sortie pour l’intégration avec des outils de gestion informatique, et le complément de ce script avec d’autres outils de surveillance pour une analyse complète du système.
Conclusion :
L’intégration de ce script PowerShell dans une suite de gestion informatique telle que NinjaOne améliore la capacité à surveiller et à maintenir la santé du système de manière efficace. La plateforme complète de NinjaOne complète les capacités du script, en fournissant une vue plus holistique de la santé et de la performance du réseau.
