#Setting up OMS to monitor container applications on ACS DC/OS
Microsoft Operations Management (OMS) is Microsoft's cloud-based IT management solution that helps you manage and protect your on-premises and cloud infrastructure. Container Solution is a solution in OMS Log Analytics, which helps you view the container inventory, performance, and logs in a single location. You can audit, troubleshoot containers by viewing the logs in centralized location, and find noisy consuming excess container on a host.
For more information about Container Solution, please refer to the Container Solution Log Analytics.
This article assumes that you have set up an DC/OS and have deployed simple web container applications on the cluster.
- Microsoft Azure Subscription - You can get this for free.
- Microsoft OMS WorksSpace Setup - see "Step 3" below
- DC/OS CLI installed.
Step 1: In the DC/OS dashboard, click on Universe and search for ‘OMS’ as shown below.
Step 2: Click on Install. You will see a pop up with the OMS version information and an ‘Install Package’ or `Advanced Installation` button. When you click on the ‘Advanced Installation’ button. Once you click the button, it will lead you to ‘OMS specific configuration properties’ page.
Step 3: Here, you will be asked to enter the wsid (OMS workspace id and wskey (OMS Primary key for the workspace id). To get both wsid and wskey you need to create an OMS account at https://mms.microsoft.com. Please follow the steps to create an account. Once you are done creating the account, you will be directed to an overview page as shown below.
- Settings -> 2) Connected Sources -> 3) Linux Servers
You will get both the workspace id and the workspace key (shown in 4. below) that you can copy paste in the OMS configuration pop up.
Step 4: Select the number you OMS instances that you want and click the ‘Review and Install’ button. Typically, you will want to have the number of OMS instances equal to the number of VM’s you have in your agent cluster. OMS Agent for Linux is installs as individual containers on each VM that it wants to collect information for monitoring and logging information.
Once you have installed the OMS Agent for Linux on the VMs, next step is to set up the OMS dashboard. There are two ways to do this: OMS Portal or Azure Portal.
Log in to OMS port (https://mms.microsoft.com) and go to Solution Gallery.
Once you are in Solution Gallery, select Containers.
Once you’ve selected the Container Solution, you will see the tile on the OMS Overview Dashboard page. Once the ingested Container data is indexed, you will see the tile populated with information on the solution view tiles.
Login to Azure Portal at https://azure.microsoft.com/. Go to Marketplace, select “Monitoring + management” and click on “See All” link. Then Type ‘containers’ in search. You will see ‘Containers’ in the search results. Select ‘Containers’ and click ‘Create’.
Once you click ‘Create’, it will ask you for your workspace. Select your workspace or if you do not have one, create a new workspace.
Once you’ve selected your workspace, click ‘Create’.
For more information about Container Solution, please refer to the Container Solution Log Analytics.
In case you need to have installed OMS agent short of the actual node count or you are scaling up VMSS by adding more VM, you can do so by scaling the `msoms` service.
You can either go to Marathon or DC/OS UI Services tab and scale up to your node count.
This will deploy to other nodes which has not being deployed OMS agent.
To uninstall MS OMS enter the following command:
$ dcos package uninstall msomsWhat works? What is missing? What else do you need for this to be useful for you? Let us know at [email protected].
