OMS Service Map solution automatically discovers application components, processes and services on Windows and Linux systems and maps the communication between them. In order to use this solution, you need to deploy the Service Map Dependency Agent for the respective OS. As you can see in the below diagram, this agent does not transmit any data by itself, but rather transmits data to the OMS agent which will then publish the data to OMS.
Microsoft has announced the release of a new Azure VM extension that will allow you to automatically deploy the dependency agent for Service Maps. Since Service Maps supports both Windows & Linux, there are two variants of this extension. One thing you do have to remember is that the dependency agent still depends on (ah the irony) the OMS agent and your Azure VMs need to have the OMS agent installed and configured prior deploying the dependency agent.
Installing the dependency agent with Azure VM extension (PowerShell)
Following is a PowerShell code snippet (from Microsoft) that will allow you to install the Service Map on all VMs in an Azure resource group.
Installing the dependency agent with Azure VM extension (ARM Template)
However Microsoft didn’t publish any official reference on to deploy the Azure VM extension for deploying the dependency agent using ARM templates (as of yet). My colleague MVP Stanislav Zhelyazkov has published a blog post on how to do this with ARM templates. You can find his reference template from GitHub.
This VM extension is currently available in the West US region and Microsoft is rolling it out all Azure regions in the next couple of days.
OMS Service Map solution is capable of automatically discovering dependencies of application components in Windows & Linux servers to map the communication flow between your business services. It maps connections between servers, processes, and ports across any TCP-connected server in your datacentre. With this solution you won’t have to configure anything besides installing an agent. Microsoft has recently released a public preview version of Service Map management pack which allows you to automatically create distributed application dashboards in SCOM based on the dynamic dependency maps generated in Service Map solution. In my opinion this is a very valuable integration as organizations that use SCOM as their main monitoring tool can leverage the dynamic application dependency monitoring capabilities of OMS, where as is past they had to rely on third party tools to visualize such.
What is inside the Service Map MP ?
Like every other management pack you need to first import the Service Map MP into SCOM. When you import the Service Map MP (Microsoft.SystemCenter.ServiceMap.mpb) following dependent MPs will be installed in your SCOM management server/s.
Microsoft Service Map Application Views
Microsoft System Center Service Map Internal
Microsoft System Center Service Map Overrides
Microsoft System Center Service Map
This management pack is compatible with both SCOM 2016 & 2012 R2 versions.
Known Limitations of the Public Preview
In the beginning of this post I have mentioned that this MP is still in preview and hence there are few issues and limitations with it as of now. I’m not sure whether Microsoft is going to address or change the behaviour some of these when the MP releases GA, specifically the limitations around updating the diagram views in SCOM console.
One management group can be integrated with only one OMS workspace.
Adding servers to the Service Map Servers Group manually won’t immediately sync those with service maps as they will be synced from Service Map during the next synchronization schedule.
Making changes to the Distributed Application Diagrams created by this MP is not useful. Because these changes will be overwritten by the Service Maps solution in the next synchronization schedule.
If you are interested in trying out this new MP, following resources might come in handy.
I have recently authored a whitepaper titled “Born in the Cloud: Monitoring Linux workloads with OMS” published by Savision. This whitepaper focuses on Linux workload monitoring capabilities of Microsoft OMS born-in-the-cloud management suite which is capable of managing and protecting heterogeneous on-premises, cloud and hybrid data centers.
Following are the key areas of discussion in my whitepaper.
What Microsoft Operations Management Suite is and how it can simplify data center management.
Leveraging OMS Log Analytics to analyze, predict and protect your Linux workloads.
Integrating System Center Operations Manager with OMS for extended monitoring.
Harnessing the power of Business Service Monitoring of Savision Live Maps Unity in Microsoft OMS.
