Fetch the queue size of ADO agents

Hello,

I am trying to build auto-scaling solution to scale private ADO agent pool based on the queue size.

I see following message when the pool is full

The agent request is not running because all potential agents are running other requests. Current position in queue: 1

I would like the queue position value using ADO API and use it as metric to scale up/down the pool instances.

Could you please help.

Thanks,

Raghav.
