iControl API incorrect?

Hi,

I'm trying to get statistics like CPU usage from a device. I'm using C on .NET. In the iControl API for 9.2.2, it says that I can use System.SystemInfo.get_cpu_usage_information() to this end.

So I went into the samples/ folder for the 9.2.2 sdk but the .cs file generated from System.SystemInfo.wsdl in there was out-of-date and didn't have this new method -- so I re-created a new .cs file from System.SystemInfo.wsdl. No big deal.

I created the new .cs file, but when I try get_cpu_usage_information(), like so,

LocalLBVirtualServer virtualServer = new LocalLBVirtualServer();
SystemInfo.SystemCPUUsage[] cpu_usages = systemInfo.get_cpu_usage_information().usages;

... I get the following error:

An unhandled exception of type 'System.Web.Services.Protocols.SoapHeaderException' occurred in system.web.services.dll

Additional information: Unknown method "{urn:iControl:System/SystemInfo}:get_cpu_usage_information"

I really need to get the CPU usage from this device for a project I'm doing. Anyone have a clue as to what's going on?

Thanks if you have any ideas,

Brian

    Just checked, and apparently I'm running 9.1.x on my device and this feature, get_cpu_usage_information(), was only added in 9.2 -- so this is why I'm having the SOAP error.

     

     

    But does anyone know how I can get CPU usage without this function if I have 9.1?

     

     

    Thanks,

    This information is not exposed programmatically until v9.2. For versions prior to this the only way I know how to get it is via console access and a combination of system commands.
