Query Current Connections at the Node Level

I am working on Powershell scripts to do automated deployments to our servers behind our BIG-IP LTM.

I have simple scripts that use the iControl powershell cmdlets

Disable-F5.LTMNodeAddress -Node xxx.xxx.xxx.xxx

These work quite well, however, what I need next is a way to query the Current Connections to the node as they bleed off so that my automation doesn't begin the deployment until current connections = 0.

I'm assuming I'm just not formatting my searches right as someone must have figured this out by now. Any help would be greatly appreciated.

Thanks!
