How to execute commands via web service sdk

Hello,

    I want to develop a web client plug-in. This plug-in is used to display hardware information on ESXi. The hardware vendor provides a command-line tool. My question is how to call the command line on ESXi through web service sdk. As far as I know, web service sdk provides a ‘ServiceManager’ class(http://pubs.vmware.com/vsphere-55/index.jsp#com.vmware.wssdk.apiref.doc/vim.ServiceManager.html) .

However, I found that it contains only two commands(Esxtop and VscsiStats ). How to put my command added to the list of commands in ServiceManager.

     Thanks.
