In this post we take a look at a vRealize Operations (vROps) deployment for vSphere 7; building on the installation of vCenter 7.0 U1 and vSAN 7.0 U1. Shortly after installing vROps 8.2, vRealize Operations 8.3 was released. The install process is similar, you can read what’s new here and see the upgrade process here.
vRealize Operations is an IT operations management tool for monitoring full-stack physical, virtual, and cloud infrastructure, along with virtual machine, container, operating system, and application level insights. vROps provides performance and capacity optimisation, monitoring and alerting, troubleshooting and remediation, and dashboards and reporting. vROps also handles private costings, showback, and what-if scenarios for VMware, VMware Cloud, and public cloud workloads. Many of these features have been released with version 8.2, and now work slicker fully integrated into the vROps user interface, rather than a standalone product. Previously vRealize Business would cater for similar costing requirements, but has since been declared end of life.
vRealize Operations can be deployed on-premises to an existing VMware environment, or consumed Software-as-a-Service (SaaS). vRealize Operations Cloud has the same functionality, with the ongoing operational overhead of lifecycle management and maintenance taken care of by VMware. Multiple vCenter Servers or cloud accounts can be managed and monitored from a single vROps instance. For more information on vROps see the What is vRealize Operations product page.
vRealize Operations Manager 8.2 Install Guide
The vRealize Operations Manager installation for lone instances is really straight forward, as is applying management packs for monitoring additional environments. Where the installation may get more complex, is if multiple cluster nodes need to be deployed, along with remote collector nodes, and/or multiple instances. If you think this may apply to you review the complexity levels outlined in the vRealize Operations Manager 8.2 Deployment Guide.
The installation steps below walk through the process of installing vROps using the master node. All deployments start out with a master node, which in some cases is sufficient to manage itself and perform all data collection and analysis operations. Optional nodes can be added in the form of; further data nodes for larger deployments, replica nodes for highly available deployments, and remote collector nodes for distributed deployments. Remote collector nodes, for example, can be used to compress and encrypt data collected at another site or another VMware Cloud platform. This could be an architecture where a solution like Azure VMware Solution is in use, with an on-premises installation of vROps. For more information on the different node types and availability setups see the deployment guide linked above.
When considering the deployment size and node design for vROps, review the VMware KB vRealize Operations Manager Sizing Guidelines, which is kept up to date with sizing requirements for the latest versions. The compute and storage allocations needed depend on your environment, the type of data collected, the data retention period, and the deployment type.
Before starting ensure you have a static IP address ready for the master node, or (ideally and) a Fully Qualified Domain Name (FQDN) with forward and reverse DNS entries. For larger than single node deployments check the Cluster Requirements section of the deployment guide.
The vRealize Operations Manager appliance can be downloaded in Open Virtualisation Format (OVF) here, and the release note for v8.2.0 here. As with many VMware products a 60 day evaluation period is applied. The vRealize Operations Manager OVF needs to be deployed for each vROps cluster node in the environment. Deployment and configuration of vRealize Operations Manager can also be automated using vRealize Suite Lifecycle Manager.
Log into the vSphere client and deploy the OVF (right click the data centre, cluster, or host object and select Deploy OVF Template).
The deployment interface prompts for the usual options like compute, storage, and IP address allocation, as well as the appliance size based on the sizing guidelines above. Do not include an underscore (_) in the hostname. The disk sizes (20 GB, 250 GB, 4 GB) are the same regardless of the appliance size configured. New disks can be added, but extending existing disks is not supported. Also be aware that snapshots can cause performance degradation and should not be used. For this deployment I have selected a small deployment; 4 CPU, 16 GB RAM.
Once deployed browse to the appliance FQDN or IP address to complete the appliance setup. You can double check the IP address from the virtual machine page in vSphere or the remote console. For larger environments and additional settings like custom certificates, high availability, and multiple nodes select New Installation. In this instance since vROps will be managing only a single vCenter with 3 or 4 hosts I select the Express Installation.
The vRealize Operations Manager appliance will be set as the master node, this configuration can be scaled out later on if needed. Click Next to continue.
Set an administrator password at least 8 characters long, with an uppercase and lowercase letter, number, and special character, then click Next. Note that the user name is admin, and not administrator.
Click Finish to apply the configuration. A loading bar preparing vRealize Operations Manager for first use will appear. This stage can take up to 15 minutes.
Login with the username admin and the password set earlier.
There are a few final steps to configure before gaining access to the user interface. Click Next.
Accept the End User License Agreement (EULA) and click Next.
Enter the license information and click Next.
Select or deselect the Customer Experience Improvement Program (CEIP) option and click Next. Click Finish to progress to the vROps user interface.
Finally we’re into vRealize Operations home page, take a look around, or go straight into Add Cloud Account.
Select the account type, in this case we’re adding a vCenter.
Enter a name for the account, and the vCenter Server FQDN or IP address. I’m using the default collector group since we are only monitoring a small lab environment. You can test using Validate Connection, then click Add.
Give the vCenter account a few minutes to sync up, the status should change to OK. A message in the right-hand corner will notify that the vCenter collection is in progress.
Back at the home page a prompt is displayed to set the currency; configurable under Administration, Management, Global Settings, Currency. In this case I’ve set GBP(£). For accurate cost comparisons and environment specific optimisations you can also add your own costs for things like hardware, software, facilities, and labour. Cost data can be customised under Administration, Configuration, Cost Settings.
A common next step is to configure access using your corporate Identity Provider, such as Active Directory. Click Administration, Access, Authentication Sources, Add, and configure the relevant settings.
Multiple vCenter Servers can be managed from the vRealize Operations Manager interface. Individual vCenter Servers can also access vROps data from the vSphere client, from the Menu dropdown and vRealize Operations. A number of nested ESXi hosts are shut down in this environment which is generating the critical errors in the screenshot.
