Question

Azure VM added to a data Collection Rule, but the VM is still appearing as not monitored on monitor vm insight

Mohamed jihad bayali 1,136

Hello,

I'm new to Azure, i just created a virtual machine and intended to monitor it.

I want to monitor it using Azure Agent monitor and not log analytic Agent.

So i started by creating a workspace analytic workspace, then i created a data collection rule, i added my virtual machine to that rule.

After creating the Rule, the monitor agent was deployed successfully on the Azure VM (i can see it on the vm's extension), but the issue is that when i go to monitor,Virtual machines,insight, i see that my VM is still apearing as not monitored and the agent is not enabled, normally it should appear as monitored right?

If i try to enable the agent, the data collection rule that i created isn't appearing on the list, it suggest me to create a new one.

Note that, the Data collection Rule, The analytic workspace, and the virtual machine are hosted on the same Region.

Is there something i'm doing wrong?

Thanks

Hi @Mohamed jihad bayali ,

Thank you for reaching out to Microsoft Q&A for this question.

I see that you have already created DCR (Data Collection Rule) and the VM has required extension enabled. Note that DCR and VMInsights are 2 different features under Azure Monitor for monitoring VMs

DCR - DCRs specify what data should be collected, how to transform that data, and where to send that data. Here you control what data to collect and where to send it.

VM Insights - VM insights monitors the performance and health of your virtual machines and virtual machine scale sets, including their running processes and dependencies on other resources. Here, the set of rules for data collection is pre-defined and does not require any tweaking after you enable it.

Therefore, creating DCR does not automatically enable VMInsights on the VM. It has to be done separately.

Please let me know if you have any questions.

Hello AnuragSingh-MSFT,

Thank you a lot for this answer, it's more clear for me now, i thought VM insight and datacollection Rule were the same thing, since from VM insight we are prompted to create/use existing DCR.

I just have one question, with VM insights can we collect logs (Event logs)? or in this case we need to create a separate DCR, and specify the required logs on the data source?

Thanks again for your explanation

@Mohamed jihad bayali , thank you for the reply. VM Insights has predefined configuration which can not be changed. Therefore, you will have to create custom rules through DCR if a log is required to be collected. Please check if this particular log is already being collected through VM Insights before creating the rule, to avoid duplicate entry.

Following on from that comment, OP states that when he tries to enable from the insights menu the DCR that was already created is not found. I have this same issue. How do we go about finding why the DCR is not showing up in the enable insights tab on the VM?

Simon Baker, thank you for the question. The "enable insights" is related to VM Insights which is a solution based on the Log Analytics workspace and other Azure Monitor components. For more details, see Overview of VM insights

In your case, as you have created DCR and attached it to VM, it will not be shown under insights overview of VM. You should be able to review it using the "Monitoring configuration" command though, as shown below:

Hope this helps.

If you have any followup question, please feel free to post it as a new question with relevant information/screenshot to help better understand it.

Thanks, I think I've got my head around it now. Bit confusing that not all DCRs are equal and if you edit the VM insights DCR it becomes a monitor DCR and no longer works with insights.
