The purpose of this plugin is to get information on the Windows Terminal Services / Remote Desktop Session Host Usage and return this back to Nagios.

The plugin runs without any arguments, it will just return a service status of OK.

The plugin is not designed to return critical or warning states, it's core purpose is to gather data for historical analysis.
This plugin is designed to be run by NSClient++ on the host you want to check. It is not designed to allow you to check a remote host, this is why there is no option to specify the host name.

Session Information:
The plugin will report how many RDP sessions are Active, Idle or Disconnected.
This is a way to look at daily trends and understand how loaded your servers are.

RDP Bytes:
This plugin will report the total RDP Input and Output bytes of all sessions.
Once again this is a way to look at daily trends and understand how much RDP traffic is generated by your RDP servers. For example users may be transferring files via the RDP protocol, this will be highlighted when looking at the historical data.

Configuring Nagios and NSClient++

The following shows you how to configure your Command AND Service definitions.
Command Definition:
define command {
command_name get_rdp_info
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c get_rdp_info

Service Definition:
define service {
host_name your_host
service_description RDP Info
check_command get_rdp_info
max_check_attempts 3
check_interval 3
retry_interval 3
register 1

Version 0.3.x
Copy the plugin to the scripts directory.
Add the following to the [External Scripts] section in NSC.ini:
get_rdp_info=cscript.exe //T:30 //NoLogo scriptsget_rdp_info.vbs

Nagios PNP Performance Graph Template
A custom pnp performance graph template has been provided, this generates two seperate performance graphs.
The file must be placed into the pnp/templates directory on your Nagios host. I have only tested this on Nagios XI and the default location on a Nagios XI host is /usr/local/nagios/share/pnp/templates.
NOTE: The name of the file MUST match the name of the Command Definition command_name. In the example above it is called get_rdp_info and hence this is why the template is called get_rdp_info.php.

Version Notes:
2012-10-05 Initial release.

2012-10-10 Updated plugin performance data to include the name of the plugin as the ending string, pnp will see this and use the custom pnp template. This works if you are using this plugin as a passive check.

Hey, just found your plugin. However, doing a test from the commandline or executing the .VBS within Windows, all values are 0.
(Nagios 3.4.1)

May you be able to help?
