I'm working in a hybrid cloud environment where we have the majority of our infrastructure in Azure, but we have some on premises machines that we also want to monitor and aggregate their log data into the same log analytics workspace.
I've successfully installed the OMS Agent for Linux and I can see that at least performance metrics and heartbeat is being collected from our local machine after following this guide. However, I can't find any guidance on how to get logs from Docker containers from on-prem to cloud.
On the on-prem machines we are running Docker, no clusters. We have some IoT Edge modules that are being managed and deployed through the IoT Hub, although I guess it is the same procedure to collect these logs since it is still Docker.
How should I got about getting my Docker logs to log analytics using the OMS agent? Is the OMS agent what I need?
It was my own error. When I reinstalled the agent I could see in the logs that the Docker version was too old for the agent to handle, so it was skipped. Updated Docker and it works.

I have onboarded an ARO Cluster in the Azure Container insight as shown in the picture below, but no data is being reported (no nodes, no pods..etc).
I have deployed the Oms Agent in openshift using DeamonSet and I can see Heartbeats sent by the agents (Pods) in the Log Analytics workspace.
Could you please help on getting the ARO cluster correctly onboarded in Azure Container Insight?
Thank you.
From Microsoft support :
This is because ARO is no longer a supported resource type for Container Insights, as per this notice: https://azure.microsoft.com/en-us/updates/azure-monitor-containers-insights-support-for-azure-red-hat-openshift-v4x-will-be-retired-by-31-may-2022/
You should Arc enabled your ARO cluster and setup Container Insights following these instructions: https://learn.microsoft.com/en-us/azure/azure-monitor/containers/container-insights-enable-arc-enabled-clusters
I have some Azure Functions deployed. Now I want to send logs data to Elastic to be able to manage these logs in Kibana. For that I should use Filebeat.
The first instruction I receive there is "install Filebeat on each system you want to monitor", so I am not getting where should I install the Filebeat. The system I want to monitor are these functions that are deployed in Azure. There is something I am not understanding. I someone can help me, I will appreciatte it!
The system I want to monitor are these functions that are already deployed in Azure, I should install Filbeat in the Azure portal? That makes no sense.
I understand that the Filebeat process will be hearing an event-hub where I will send my logs, to send that logs to the elastic cloud. But I don't understand where I should install this Filebeat process.
Finally we need to create a Virtual Machine in Azure with Windows as OS, and we installed the Filebeat there.
At end is a service (a windows service in our case) that is hearing the event hub.
I have created a custom OS images on Azure containing my app, omsagent, and a configuration file to track my application logs. I verified that the custom logs were available on Log Analytics Workspace for that VM.
When I create a new VM with this custom OS, using Python SDK, I don't receive logs in the workspace. I verified that omsagent is working. It is sending heartbeats that are visible on the Log Analytics Workspace > Insights > Agents.
I found out that the new is was not Connected to the workspace.
So my question is how do I automatically connect a VM to Log Analytics Workspace at creation time?
I would advise against baking the Log Analytics Agent (OMS Agent) into the image directly - Azure doesn't recommend this kind of setup. Instead, you should be using an Azure Policy that they provide exactly for this scenario.
We have dozens of VMs and Scale Sets we need to manage with Log Analytics Agent installed on each of them when we build the custom images. In the beginning everything was working fine but a couple of months later those images stopped working.
After spending some time investigating with the Azure team we found out that the agent's certificate wasn't being renewed and it wouldn't connect to the Workspace automatically. Even worse was that because of this, it was failing all our images builds.
We were told that this is not the right practice and we should look at Azure Policies. They are rather easy to setup - just assign once and forget about them. It's also good for compliance and will let you know if there's any machine that's non-compliant.
Check this link for more info about Azure Monitor policies.
And this link will open your Azure Portal directly into the policies page for Windows VMs.
Here's a preview of the policies available:
As per the title, I just want all stdio output from this service to be sent to a cloud resource like cloudwatch logs or Azure Monitor so I can just read them in a time span. All stdio lines should be there.
The documentation for this seems nonexistent
This really depends on what tech that API is built on and what OS your VM is hosting. But the simplest way is IMO to enable the monitoring agent on your VM. Create a Log Analytics workspace and attach your VM straight from the portal. This way you can subscribe to different sources of logs and make them appear in your LA workspace, to be queried and filtered for further analysis.
Docs here: https://learn.microsoft.com/en-us/azure/azure-monitor/learn/quick-collect-azurevm
You output from your API can then within the VM be directed to either Windows EventLog or Linux syslog, which is supported out of the box in Log Analytics workspace and the monitoring agent. If your API runs in a container, say with docker, you can enable a special container monitoring solution on your created LA workspace - or you can configure docker to direct container logs to either syslog or EventLog directly.
If you run docker containers, here's a guide for configuring the logging driver: https://docs.docker.com/config/containers/logging/syslog/
If you run you API on IIS, you can simply enable IIS logs fetching on your LA workspace from the portal. However, this will only send HTTP logs and not stdout as far as I know.
If Anything else, please enhance your question.
I need to gather different kinds of logs:
Logs of applications running into docker machines orchestrated by Kubernetes.
Logs differents from metrics.
Which tool is more appropriate to do that?
My infrastructure is composed by Kubernetes orchestring docker machines installed in Microsoft azure (using ACS engine and RPM).
You can use Application Insights. App Insights can be used to store logging/monitoring for Docker Apps easily
See this blog for understanding how Application insights support microservices and containers.
You can easily pull the microsoft/applicationinsigthts image from docker hub and start using it.
Here the pricing calculator for application insights (Microsoft will give 5GB of Storage for logs free for every month)
