Windows Server Status Monitor

 ·  ☕ 5 min read

PowerShell based Windows Server monitor

I wanted to create a lightweight and easy to setup server status monitor. It needed to highlight any metrics that were outside of a customisable threshold visually and be able to e-mail the report or run continuously. Based on a script from Bhavik Solanki (on TechNet) and with some help from my good friend, and software developer Dan Price, we created WinServ-Status, now known as Windows Server Status Monitor.

Windows Server Status Monitor can also be downloaded from:

Please report any problems via the ‘issues’ tab on GitHub.


Features and Requirements

  • The utility will display the server name, uptime, CPU, memory and storage information, online status.
  • The utility can be configured with a customisable alerts for the CPU, memory and storage.
  • The utility can display the results as either a CSV file or a HTML file.
  • The utility can be configured to monitor continuously, or run once.
  • The utility can be configured to e-mail the results.
  • This utility has been tested running on Windows 10 and Windows Server 2016, monitoring PCs and Servers running Windows 10, Windows Server 2016, Windows Server 2012 R2, and Windows Server 2008 R2.
  • The utility must be run as a user with administrator-level privileges to the systems it is monitoring.

Generating A Password File For SMTP Authentication

The password used for SMTP server authentication must be in an encrypted text file. To generate the password file, run the following command in PowerShell, on the computer that is going to run the script and logged in with the user that will be running the script. When you run the command you will be prompted for a username and password. Enter the username and password you want to use to authenticate to your SMTP server.

Please note: This is only required if you need to authenticate to the SMTP server when send the log via e-mail.

$creds = Get-Credential
$creds.Password | ConvertFrom-SecureString | Set-Content c:\scripts\ps-script-pwd.txt

After running the commands, you will have a text file containing the encrypted password. When configuring the -Pwd switch enter the path and file name of this file.


Here’s a list of all the command line switches and example configurations.

Command Line Switch Description Example
-List The path to a TXT file containing the NetBIOS names of the servers you wish to check. [path]servers.txt
-O The path where the report file will be output to. [path]
-DiskAlert The percentage of disk usage that should cause the disk space alert to be raised. [number]
-CpuAlert The percentage of CPU usage that should cause the CPU alert to be raised. [number]
-MemAlert The percentage of memory usage that should cause the memory alert to be raised. [number]
-Refresh The number of seconds that she script should wait before running again. The minimum is 300 seconds (5 minutes) and the maximum is 28800 (8 hours). If not configured the script will run once and then exit. [number]
-Light Configure the HTML results file to have a light theme. N/A
-csv Export a CSV file, instead of a HTML file. [path]
-Subject Specify a subject line. If you leave this blank the default subject will be used “'[Server: Notification]'”
-SendTo The e-mail address the log should be sent to. For multiple address, separate with a comma. [[email protected]]
-From The e-mail address the log should be sent from. [[email protected]]
-Smtp The DNS name or IP address of the SMTP server. [smtp server address]
-User The user account to authenticate to the SMTP server. [[email protected]]
-Pwd The txt file containing the encrypted password for SMTP authentication. [path]ps-script-pwd.txt
-UseSsl Configures the utility to connect to the SMTP server using SSL. N/A


WinServ-Status.ps1 -List C:\foo\servers.txt -O C:\foo -DiskAlert 90 -CpuAlert 95 -MemAlert 85 -Refresh 300 -Light

Using the switches above the script will execute using the list of servers and output a HTML report to C:\foo. The disk usage alert will highlight at 90% usage for any one drive, the CPU usage alert will highlight at 95% usage, and the memory usage alert will highlight at 85% usage. The status of the servers will refresh every 5 minutes, and the HTML file will have a light theme instead of a dark theme.
