Azure Monitor Agent - no Computer name in Log Analytics workspace

Question

Hi,
I'm facing an issue related the azure monitor agent, I'm trying to migrate from the legacy agent.

I've successfully configured a DCR to collect the IIS logs, and I can see them in the Log analytics workspace.

But the "Computer" (Hostname) field stays blank:

(Have the same issue with the custom Logs as well).

I have configured a 3. DCR for the Metrics & Heartbeat, and this one is working fine, I can see the hostname for each computer.

Thank You!

@ZC Thank you for your questions.

Based on the discussion here it seemed to be related to an existing version which should be resolved now.

Can you please try updating the Azure Monitor Agent installed on the VM/VMSS to see if that helps? As mentioned in the link above,

The recommendation is to enable Automatic Extension Upgrade which may take up to 5 weeks after a new extension version is released for it to update installed extensions to the released (latest) version across all regions. Upgrades are issued in batches, so you may see some of your virtual machines, scale-sets or Arc-enabled servers get upgraded before others. If you need to upgrade an extension immediately, you may use the manual instructions below.

If the update does not help, I would suggest reaching out to Azure Support with the information as mentioned here. As the issue would require 1:1 investigation of this particular environment.
