La d\u00e9tection des temps d’inactivit\u00e9 sur les ordinateurs est un aspect crucial pour les professionnels de l’informatique, en particulier face \u00e0 l’augmentation des menaces de cybers\u00e9curit\u00e9 et aux probl\u00e8mes de gestion des ressources. Les entreprises sont de plus en plus num\u00e9ris\u00e9es et les utilisateurs restent souvent connect\u00e9s pendant de longues p\u00e9riodes. Il est donc primordial de d\u00e9tecter les temps d’inactivit\u00e9 des utilisateurs<\/strong> pour des raisons de s\u00e9curit\u00e9 et de fonctionnement. Dans cet article, nous allons nous plonger dans un script PowerShell con\u00e7u pour d\u00e9tecter le temps d’inactivit\u00e9 des utilisateurs le plus long, ce qui rend la t\u00e2che simple et efficace.<\/p>\n

Contexte<\/h2>\n

La possibilit\u00e9 de d\u00e9terminer le temps d’inactivit\u00e9 d’un utilisateur peut fournir des informations pr\u00e9cieuses aux professionnels de l’informatique et aux fournisseurs de services g\u00e9r\u00e9s (MSP). Qu’il s’agisse de lib\u00e9rer des ressources, de s’assurer que les sessions ne restent pas expos\u00e9es \u00e0 des menaces de s\u00e9curit\u00e9 potentielles, ou m\u00eame de prendre en compte les aspects li\u00e9s \u00e0 la facturation pour les fournisseurs de services cloud, il est essentiel de disposer d’une m\u00e9thode efficace et fiable pour d\u00e9terminer l’inactivit\u00e9 de l’utilisateur. Ce script particulier exploite les prouesses de PowerShell pour interagir directement avec le syst\u00e8me d’exploitation Windows et extraire des donn\u00e9es pertinentes pour \u00e9valuer les temps d’inactivit\u00e9.<\/p>\n

#Requires -Version 5.1\r\n\r\n<#\r\n.SYNOPSIS\r\n    Returns the longest idle time of any user logged in or for a specific user.\r\n.DESCRIPTION\r\n    Returns the longest idle time of any user logged in or for a specific user.\r\n    If RDS(Remote Desktop Services) is installed and the RSAT tools for it as well,\r\n     then this will get the idle time of each logged in user.\r\n    For workstations and servers(with out RDS installed),\r\n     this will get the current idle of the currently logged in user.\r\n    If a user is logged in via the console and another is via the admin RDP session,\r\n     then both will be considered as one user for calculating idle time.\r\n.EXAMPLE\r\n    No parameters needed.\r\n    Returns the longest idle time of all users logged in.\r\n.EXAMPLE\r\n     -UserName \"Fred\"\r\n    Returns the longest idle time of the user Fred.\r\n.EXAMPLE\r\n    PS C:> Get-User-Idle-Time.ps1 -UserName \"Fred\"\r\n    Returns the longest idle time of the user Fred.\r\n.OUTPUTS\r\n    PSCustomObject[]\r\n.NOTES\r\n    Minimum OS Architecture Supported: Windows 10, Windows Server 2016\r\n    Release Notes:\r\n    Adds functions to get idle time from RDS and non-RDS computers.\r\nBy using this script, you indicate your acceptance of the following legal terms as well as our Terms of Use at https:\/\/www.ninjaone.com\/terms-of-use.\r\n    Ownership Rights: NinjaOne owns and will continue to own all right, title, and interest in and to the script (including the copyright).
