Objectives

  • Configure FluentBit
  • Deploy FluentBit
  • Access vRealize log insight to view logs

Configure Fluentbit

  1. Using the terminal, navigate to the fluent-bit directory.

    cd ~/Workspace/tkg-extensions-v1.3.1+vmware.1/extensions/logging/fluent-bit

  2. Make a copy of the example Syslog settings.

    cp syslog/fluent-bit-data-values.yaml.example fluent-bit-data-values.yaml

  3. Open fluent-bit-data-values.yaml in Visual Studio Code.

    code fluent-bit-data-values.yaml

    Untitled

    1. Modify the following parameters within < >

      1. Instance = TKG Instance or Management Cluster
      2. Cluster = tkc-01 = workload cluster

      Untitled

    2. Save the file and close Visual Studio Code.

    3. Verify that the configuration file matches the reference configuration file.

    checkconfig fluent-bit-data-values.yaml

    When a configuration mismatch exists, Visual Studio Code opens the configuration file in the left panel and the reference configuration file in the right panel.

    1. If a configuration mismatch exists, modify the configuration on the left to match the reference configuration on the right.

      Differences are highlighted in red.

    2. Save the file and close Visual Studio Code.

Deploy FluentBit

  1. Using the terminal, navigate to the fluent-bit directory.

    cd ~/Workspace/tkg-extensions-v1.3.1+vmware.1/extensions/logging/fluent-bit

  2. Set the kubectl context to the tkc-01 cluster.

    kubectl config use-context tkc-01-admin@tkc-01

  3. Create a namespace for Fluent Bit.

    kubectl apply -f namespace-role.yaml

  4. Create a Kubernetes secret from the settings file.

    kubectl create secret generic fluent-bit-data-values --from-file=values.yaml=fluent-bit-data-values.yaml -n tanzu-system-logging

  5. Deploy Fluent Bit.

    kubectl apply -f fluent-bit-extension.yaml

  6. Verify the status of the deployment by using kubectl.

    kubectl get app fluent-bit -n tanzu-system-logging

    Re-run the command until the status displays as Reconcile succeeded.

  7. Verify the status of the deployment by using kapp.

    kapp list -n tanzu-system-logging

    kapp inspect --app fluent-bit-ctrl -n tanzu-system-logging

Access VRealize Log Insight to View Logs

  1. In Firefox, open the vRealize Log Insight bookmark in a new tab.

    https://sa-loginsight-01.vclass.local/

  2. Log in to vRealize Log Insight.

    • User name: admin
    • Password: VMware1!

  3. Click Interactive Analytics.

    The logs for tkc-01 display.
