understanding auto-scale - doesn't seem to be working

Some quick background info: I'm not the person who set up or administered our AVD/Nerdio Manager environment but took it over when that person unexpectedly left the company. Nerdio version that we're currently on is 7.0.2.

I'm trying to understand why I'm not seeing any available devices in one of our dynamic host pools.

Right now all devices in that host pool are assigned to a user. When I select ‘Auto-scale > Manage' for that host pool, Auto-grow is set to 2 desktops. Auto-scale mode is ‘User driven’. I've confirmed Auto-scale is set to ‘On’ for the pool.

I currently have three users trying to connect but I'm not seeing any AVDs being added to the host pool. I'm also experiencing the same thing, as I know my username has membership in that pool, so I should get an AVD, but I'm not. When I try to connect via Windows App, I get the following error: 'Unable to connect: We couldn't connect because there are currently no available resources. Try again later, or contact your network administrator for assistance. Error code: 0x5000057'.

We have a few other dynamic host pools and auto-scaling seems to be working just fine for those. I haven't yet spotted anything that appears to be different in terms of configuration for auto-scale among the pools.

I don't know what other settings I should be checking or what I can do to get additional VMs to spin up.

First, since you aren't who set up and deployed AVD and Nerdio, welcome to the club!

Just to get you into the right place promptly, as I can't tell how critical this is (but could be) - The version you have deployed, I believe describes that you have Nerdio Manager for Enterprise (and you posted in a support forum for partners).    Shouldn't be hard for you to find the right site but I'll defer to someone more familiar with both sides to speak in. - here is where I would start - Nerdio Manager for Enterprise

That said - without the specifics of the auto-scale configuration, its tough to pinpoint the answer.  I would highly recommend, especially if this is a production environment, that you open a support case directly.   While you don't get the assistance from the rest of the community, you are nearly guaranteed a much faster response and very direct engagement to get to the root of the problem.

That said, if you wish to continue here, I think the community would want to know exactly what the auto-scale settings are - a wide array of possible settings could be blocking the ability to scale-out to meet the demand. I'd look at triggers for what causes things to scale out, and what limits are in place to limit just how far it can scale. 

Good Luck!

Thank you for the info! I did wind up opening a support case with Nerdio and they are in the process of assisting. Thanks again for your response, much appreciated!
