05 - Monitoring the Kubernetes Cluster with OMS and Log Analytics

Create OMS workspace

Create a new OMS workspace and get a workspace ID and primary key for it by following this guide - Configure the monitoring solution.

Deploy OMS/Log Analytics DaemonSet Agent in the Cluster

Once you have the workspace ID and primary key of your OMS workspace, replace the values for WSID and KEY with your values in kubernetes/oms-daemonset.yaml

containers:
- name: omsagent
    image: "microsoft/oms"
    imagePullPolicy: Always
    env:
    - name: WSID
        value: <WSID>
    - name: KEY
        value: <KEY>

Then, install the OMS daemonset by running the following command:

kubectl create -f kubernetes/oms-daemonset.yaml --record

Check if new Pod and DaemonSet for OMS agent are running:

kubectl get po,ds -l context=AKSDemo

After this is completed, OMS starts collect metrics and logs from the cluster. Here are the OMS container solution dashboard screen capture:
