.SYNOPSIS .SYNOPSIS
Ping a host Pings a host
.DESCRIPTION .DESCRIPTION
This PowerShell script pings the given host continously and shows the roundtrip times in a horizontal chart. This PowerShell script pings the given host.
.PARAMETER hostname .PARAMETER hostname
Specifies the hostname or IP address of the host to ping (windows.com by default) Specifies the hostname or IP address to ping (windows.com by default)
.PARAMETER timeInterval
Specifies the time interval in milliseconds to repeat the ping (1000 by default)
.EXAMPLE .EXAMPLE
PS> ./ping-host.ps1 PS> ./ping-host.ps1 x.com
----------------------------------------- ✅ x.com is up with 10ms latency.
Ping Roundtrip Times to windows.com
-----------------------------------------
#1 ██████████████ 136ms
#2 ████████████████ 154ms
