System Information

The Inventua SystemInfo Module for DotNetNuke displays technical information on a nominated server, including running services, disk usage, CPU and memory utilization, server uptime and more.

Installation and Compatibility
This module is installed as part of the Inventua DNN System Monitoring kit.   Some performance monitoring statistics that are available from Windows 2003 servers such as Processor Load and number of active threads are not be available for Windows 2000 servers due to security restrictions built into the operating system. Refer to Microsoft knowledge base article 226494 for more information.

Configuration Options
Once you create a SystemInfo instance, select the Options menu item from the module settings menu to display the Options page.

Server The DNS name of the server.  If you want to refer to the DNN server, use the value "." (a single dot).
Username

The username to submit to WMI.  The user must have access rights to WMI namespaces on the selected server.  Use the wmimgmt.msc snap-in on the server to configure WMI access rights.  The username is not required and is not used when monitoring the same server that DNN in running on - it is only used when getting system information from a seperate server. 

See http://support.microsoft.com/default.aspx?scid=kb;EN-US;325353 for more details.

Password The password to submit to WMI.
Domain The domain of the username to submit to WMI.  In most cases you will be monitoring systems in the same domain as your DNN (web) server and can leave this blank.
Custom Queries

Advanced users can add custom WMI queries for display (available in the versions for DNN 3 & 4 only).  To add a custom query, enter the following:

Caption:  The label to show next to the query result.
Query:  The WMI query to execute.  (Example, "SELECT NumberOfProcesses FROM Win32_OperatingSystem").  See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/win32_classes.asp?frame=true  for more information on WMI queries.

When you have entered the Caption and Query, Click the "Add" button to add your custom query to the list.  You can remove custom queries by clicking the "delete" link in the list. 

* CPU Usage and thread count cannot be reported by Windows when your DNN/web server operating system is Windows 2000, even if the server being monitored is using Windows 2003.  If your DNN/web server is Windows 2003, CPU usage and thread count reporting will work, even if the server being reported is using Windows 2000.

The System Info module can be used in conjunction with the System Monitor module.  You can configure a "System Information" tab using System Info modules as the "details" view for your server(s), and configure another tab with the SystemMonitor module for quick monitoring.  The System Monitor module has a "Info Tab" option you can set to easily show a hyperlink to your system information page.
