zabbix_agent_installation.ps1
# ===========================================================================================
#
# NAME: Zabbix_InstallAgent.ps1
#
# AUTHOR: Pierre-Emmanuel Turcotte,
# DATE : 2012-11-05
#
# COMMENT: Remote installation of Zabbix agent from central location.
#
# The zabbix source folder is a folder containing subfolder corresponding to the
# different agent versions. These subfolders contain the win32 and win64 subfolders
# along with the zabbix_agentd.win.conf configuration file.
#
# You must have administrative priviledges on the remote computers you will specify
# in the computerName parameter. You can either use the following format:
#
# zabbix_installagent.ps1 -ComputerName server1,server2,server3
#
# or do not specify any servers, you will be prompted for servers, one at a time.
#
# Additionnally, you have the following parameters you can optionally define:
#
# -ZabbixVersion #Version of the agent to be installed(points to subfolder)
# Defaults to "2.0.3"
# -ZabbixPath #Folder where the agent installation resides on the central
# server. This is the folder that will be copied over to the
# remote locations.
# Defaults to "O:\Zabbix"
#
# About the zabbix path, on my installation, this folder holds 3 subfolders:
#
# O:\Zabbix
# \1.8.10
# \2.0
# \2.0.3
#
# $ZabbixPath and $ZabbixVersion will be assembled in a new variable named
# $ZabbixSource, look for it for a better undestanding.
#
