.PARAMETER ESPort
The port on which the Elasticsearch server is listening. Defaults to TCP 9200.

.PARAMETER ESUsername
Warning: Insecure!
The username used to authenticate to the Elasticsearch server. If ESUsername is not specified,
the script will ask for the username at runtime. In order to avoid recording the Elasticsearch
username, consider editing this file. Change the line `[string]$ESUsername="",` to
`[string]$ESUsername="YOUR_ELASTIC_USERNAME_HERE",.

.PARAMETER ESPassword
Warning: Insecure!
The password used to authenticate to the Elasticsearch server. If ESPassword is not specified,
the script will ask for the password at runtime. In order to avoid recording the Elasticsearch
password, consider editing this file. Change the line `[string]$ESPassword="",` to
`[string]$ESPassword="YOUR_ELASTIC_PASSWORD_HERE",.
.PARAMETER ESCredential
The username and password used to authenticate to the Elasticsearch server. If a powershell
credential object is not specified, the script will ask for the credentials at runtime.

.EXAMPLE
# Asks for Elasticsearch authentication details at runtime
.\install-sysmon-beats.ps1 my-es-host.com 9200

# Reads Elasticsearch authentication details from the command line aguments
.\install-sysmon-beats.ps1 my-es-host.com 9200 elastic elastic_password

.NOTES
The Elasticsearch credentials are stored locally using Elastic Winlogbeat's secure
storage facilities. The ESUsername and ESPassword parameters should not be passed
into the script in a secure environment. Instead, either leave the credentials blank and
enter the credentials during the installation process, or edit the parameters' default values in the script.
