My network admin asked me why our developement vm (D365 Update 3) is pulling so much data from the Internet. We have 5 developement VMs that pulled 232GB in the last 7 days from table.(random letters).store.core.windows.net. I have no idea what is doing that. Anyone know why a Dev VM needs to contact *.store.core.windows.net? Beside the authentication, I thought Dev VM were autonomous.

Fow now this address has been block for my VM to figure what stops working because of that.

Are those VMs deployed to Azure, or did build them locally from VHD?

Can't you find the storage account in your Azure subscription?

There can be more communication than just authentication, such at applying deployable and data packages from LCS, telemetry, PowerBI and so on. But I don't know what may be using the table storage.

Those are local VHD. The random letters are not the name of a storage account in our Azure subscription.

I'll continue using my VM while it is blocked for that URL and see if I get any error.

There is something called monagent.exe which seems to take a lot of resources. Kill all 4 of the Monagents running on your VM and that should help

It is normally found in taskManager under details tab

These are related to Azure diagnostics see https://docs.microsoft.com/en-us/azure/monitoring-and-diagnostics/azure-diagnostics-troubleshooting

Thanks for the link magic1949.

For what I know, that monagent is more of a pain than it is useful, on an Dev VM atleast. I already found out that it fills my disk space and I need to empty it's log folder from time to time, now it's eating up my bandwidth.

Can it be disabled? Like disabling a service or something like that?

Difficult to advise without more information but as far as I know there should be no problem, maybe just rename the file names with an extra extension of '.old." and then you can always remove that name change if you need to.

Hi.

We had the same issue and solved it by disabling the scheduled task "Monitoring Install". Right now the traffic is ok.
