Cluster Inspections Overview

This for me is one of the best features of Tanzu Mission Control, and an area which I expected will be developed further in the future.

Cluster inspections provide a point-in-time report of the condition of the cluster, you might want to run them periodically (to avoid drifting out of conformance) and any time you make significant alterations, such as after you patch or upgrade a cluster.

This capability is achieved by using Sonobuoy, an open source community standard, which provides diagnostics of your Kubernetes environments through conformance testing and additional plugins.

What Inspections are available?

The following cluster inspections are available from the Overview and Inspection tabs of the cluster detail page in the Tanzu Mission Control console.

  • Conformance inspection;

Validates the binaries running on your cluster and ensures that your cluster is properly installed, configured, and working. You can view the generated report from within Tanzu Mission Control to assess and address any issues that arise. For more information, see the Kubernetes Conformance documentation at https://github.com/cncf/k8s-conformance/tree/master/docs.

  • CIS benchmark inspection;

Evaluates your cluster against the CIS Benchmark for Kubernetes published by the Center for Internet Security.

  • Lite inspection;

Is a node conformance test that validates whether nodes meet requirements for Kubernetes. For more information, see Validate node setup in the Kubernetes documentation.

Performing Inspections

To perform an inspection, there are two ways; from the inspections tab when view a cluster object (as in the above screenshot).

Or you can do this from the Inspections navigation page, as below.

vRealize Operations Openshift Container Platform Monitoring header

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.
  5. Click Upload. The upload might take several minutes.
  6. Read and accept the EULA,and click Next.
  7. When the vRealize Operations Management Pack for Container Monitoring is installed, click Finish.

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.

PowerCLI

PowerCLI – Import-VApp Name or service not known

VMware, ,

I kept running into the error whilst running PowerCLI on Ubuntu. After wracking my brains, I realised that the issue is DNS, my Ubuntu box couldn’t resolve the FQDN for the ESXi host, which is a mandatory parameter for the Import-vApp command.

vCenter 7.0 – Image based backup is still supported, but won’t be in future versions

VMware, , ,

When vSphere 7.0 (and therefore vCenter 7.0) went GA, a number of customers were hit with a very important change;

  • vCenter support for image based backups was no longer supported

Since the GA, after customer feedback, the vCenter 7.0 release notes have been updated and I’m happy to report that Image based backups are still supported.

However, note that this method is now deprecated and will not be supported in a future release.

My advice is to start planning your move to using the native backup capabilities within the vCenter appliance itself, and for further information please see the following resources;

vCenter 7.0 imaged based backups supported but deprecated in the future

Veeam Backup for Azure Header 605

Veeam Backup for Azure – Unable to check required permissions.

Veeam, , ,

The Issue

When connecting my newly deployed instance of Veeam Backup for Microsoft Azure, I keep hitting the same error message after authenticating my account with Microsoft.

Error: Unable to check required permissions. This might be a problem in Microsoft Azure. Please wait and continue with the wizard later.

Simple enough message, I don’t have the right permissions, yet I knew on my test tenant I was a global admin, (and the only user configured in this tenant) so why was I seeing this error?

Veeam Backup for Azure Logon to Microsoft Azure Unable to check the required permissions

The cause

When I downloaded the logs, I found the following, it indicated that my account is connected to two tennants, both of the same name “Default Directory” to make things confusing, and the error was happening on the permissions check with the tenant.
