Workspaces

Workspaces provide an application view, where you logically group Kubernetes Namespaces together, regardless of the cluster to which they are attached.

This is in contrast to Cluster Groups, which are focused on the infrastructure view.

These Workspaces can be created to align to your projects or applications, from a hierarchy point of view, you would then authorize your users to these Workspaces, so that they can monitor and manage the namespaces related to their function.

Creating a Workspace

Click the Workspace navigation view on the left-hand side, and then New Workspace.

Tanzu Mission Control New Workspace

Specify your Workspace name, and provide the optional description and labels, these can be added after creation if needed.

Now you have a Workspace, it’s no good without any associated Namespaces, so let’s continue.

Creating a managed Namespace

All Namespaces attached to a Workspace will be managed Namespaces under TMC.

To create a managed Namespace, you can do this in one of four places;

  • Within the Workspace Navigation view
  • Inside the Workspace Object itself
  • On the Namespace Navigation view
  • On the Cluster Object > Navigation Tab

vRealize Operations – Monitoring OpenShift Container Platform environments

VMware, Kubernetes, , , ,

The latest release of  vRealize Operations (the “manager” part of the product name has now been dropped), brings the ability to manage your Kubernetes environments from the vSphere infrastructure up.

The Kubernetes integration in vRealize Operations 8.1;

  • vSphere with Kubernetes integration:
    • Ability to discover vSphere with Kubernetes objects as part of the vCenter Server inventory.
    • New summary pages for Supervisor Cluster, Namespaces, Tanzu Kubernetes cluster, and vSphere Pods.
    • ​Out-of-the-box dashboards, alerts, reports, and views for vSphere with Kubernetes.
  • The VMware Management Packs that are new and those that are updated for vRealize Operations Manager 8.1 are:
    • VMware vRealize Operations Management Pack for Container Monitoring 1.4.3

Where does OpenShift Container Platform fit in?

All though the above highlighted release notes point towards vSphere with Kubernetes (aka project pacific), the Container monitoring management pack has been available for a while and has received a number of updates.

vRealize Operations Management Pack for Containers compatiibility

This management pack can be used with any of your Kubernetes setups. Bringing components into your infrastructure monitoring view;

  • Kubernetes;
    • Clusters
    • Nodes
    • Pods
    • Containers
    • Services

So this means you can add in your OCP environment for monitoring.

Configuring vRealize Operations to monitor your OpenShift Clusters

Grab the latest Container monitoring management pack to be installed in your vRealize Operations environment.

  1. Log in to the vRealize Operations Manager with administrator privileges.
  2. In the menu, select Administration and in the left pane select Solutions > Repository.
  3. On the Repository tab, click Add/Upgrade.
  4. Browse to locate the temporary folder and select the PAK file.

vRealize Operations add Management Pack

To link any Kubernetes to your environment for monitoring, you need to install the cAdvisor Daemon.  For OCP I used the cAdvisor YAML Definition on HostPort, secondly you need to create some credentials to authenticate to your cluster from your connection in vROPs.
