#Requires -Version 3.0 #-- ping Connection to the host --# # PingAsync <# .SYNOPSIS Monitor host by Ping for selected Second .DESCRIPTION This function will pingasync to the host. You can set Interval seconds and endup limitCount to prevent eternal execution. .NOTES Author: guitarrapc Created: 27/July/2014 .EXAMPLE Watch-ValentiaPingAsyncReplyStatus -deploygroups 192.168.100.100 -DesiredStatus $true -limitCount 1000 | ft -------------------------------------------- Continuous ping to the 192.168.100.100 for sleepSec 1 sec.
