About Installing 1
When you install vRealize Operations Manager, you can install the product in an environment that has
never been monitored by vRealize Operations Manager. You can also migrate, which captures an
environment monitored by a previous version of vRealize Operations Manager so that the new copy of
vRealize Operations Manager can monitor that environment.
You can migrate at installation time, or you can postpone a migration until after your copy of
vRealize Operations Manager is in production use. In other words, you can run
vRealize Operations Manager to monitor a fresh environment, and at any time, decide to add an
environment that was being monitored by a previous vRealize Operations Manager.

Installation Overview
You prepare for vRealize Operations Manager installation by evaluating your environment and deploying
enough vRealize Operations Manager cluster nodes to support how you want to use the product.
Workflow of vRealize Operations Manager Installation
The vRealize Operations Manager virtual appliance installation process consists of deploying the
vRealize Operations Manager OVF or an installer once for each cluster node, accessing the product to set up
cluster nodes according to their role, and logging in to congure the installation.
Figure 1‑1. vRealize Operations Manager Installation Architecture

Sizing the vRealize Operations Manager Cluster
The resources needed for vRealize Operations Manager depend on how large of an environment you expect
to monitor and analyze, how many metrics you plan to collect, and how long you need to store the data.
It is dicult to broadly predict the CPU, memory, and disk requirements that will meet the needs of a
particular environment. There are many variables, such as the number and type of objects collected, which
includes the number and type of adapters installed, the presence of HA, the duration of data retention, and
the quantity of specic data points of interest, such as symptoms, changes, and so on.
VMware expects vRealize Operations Manager sizing information to evolve, and maintains Knowledge Base
articles so that sizing calculations can be adjusted to adapt to usage data and changes in versions of
vRealize Operations Manager.
Knowledge Base article 2093783
The Knowledge Base articles include overall maximums, plus spreadsheet calculators in which you enter the
number of objects and metrics that you expect to monitor. To obtain the numbers, some users take the
following high-level approach, which uses vRealize Operations Manager itself.
1 Review this guide to understand how to deploy and congure a vRealize Operations Manager node.
2 Deploy a temporary vRealize Operations Manager node.
Chapter 1 About Installing
3 Congure one or more adapters, and allow the temporary node to collect overnight.
4 Access the Cluster Management page on the temporary node.
5 Using the Adapter Instances list in the lower portion of the display as a reference, enter object and
metric totals of the dierent adapter types into the appropriate sizing spreadsheet from Knowledge
Base article 2093783.
6 Deploy the vRealize Operations Manager cluster based on the spreadsheet sizing recommendation. You
can build the cluster by adding resources and data nodes to the temporary node or by starting over.
If you have a large number of adapters, you might need to reset and repeat the process on the temporary
node until you have all the totals you need. The temporary node will not have enough capacity to
simultaneously run every connection from a large enterprise.
Another approach to sizing is through self monitoring. Deploy the cluster based on your best estimate, but
create an alert for when capacity falls below a threshold, one that allows enough time to add nodes or disk
to the cluster. You also have the option to create an email notication when thresholds are passed.
During internal testing, a single-node vApp deployment of vRealize Operations Manager that monitored
8,000 virtual machines ran out of disk storage within one week.
Add Data Disk Space to a vRealize Operations Manager vApp Node
You add to the data disk of vRealize Operations Manager vApp nodes when space for storing the collected
data runs low.
Prerequisites
Note the disk size of the analytics cluster nodes. When adding disk, you must maintain uniform size
n
across analytics cluster nodes.
Use the vRealize Operations Manager administration interface to take the node oine.
n
Verify that you are connected to a vCenter Server system with a vSphere client, and log in to the
n
vSphere client.

Complexity of Your Environment
When you deploy vRealize Operations Manager, the number and nature of the objects that you want to
monitor might be complex enough to recommend a Professional Services engagement.
Complexity Levels
Every enterprise is dierent in terms of the systems that are present and the level of experience of
deployment personnel. The following table presents a color-coded guide to help you determine where you
are on the complexity scale.
Green

About vRealize Operations Manager Cluster Nodes
All vRealize Operations Manager clusters consist of a master node, an optional replica node for high
availability, optional data nodes, and optional remote collector nodes.
When you install vRealize Operations Manager, you use a vRealize Operations Manager vApp deployment
to create role-less nodes. After the nodes are created and have their names and IP addresses, you use an
administration interface to congure them according to their role.
You can create role-less nodes all at once or as needed. A common as-needed practice might be to add nodes
to scale out vRealize Operations Manager to monitor an environment as the environment grows larger.
12 VMware, Inc.
The following node types make up the vRealize Operations Manager analytics cluster:
Chapter 1 About Installing
Master Node
Data Node
Replica Node
The following node type is a member of the vRealize Operations Manager cluster but not part of the
analytics cluster:
Remote Collector Node
The initial, required node in vRealize Operations Manager. All other nodes
are managed by the master node.
In a single-node installation, the master node manages itself, has adapters
installed on it, and performs all data collection and analysis.
In larger deployments, additional data nodes have adapters installed and
perform collection and analysis.
Larger deployments usually include adapters only on the data nodes so that
master and replica node resources can be dedicated to cluster management.
To use vRealize Operations Manager high availability (HA), the cluster
requires that you convert a data node into a replica of the master node.
Distributed deployments might require a remote collector node that can
navigate rewalls, interface with a remote data source, reduce bandwidth
across data centers, or reduce the load on the vRealize Operations Manager
analytics cluster. Remote collectors only gather objects for the inventory,
without storing data or performing analysis. In addition, remote collector
nodes may be installed on a dierent operating system than the rest of the
cluster.
About vRealize Operations Manager Remote Collector Nodes
A remote collector node is an additional cluster node that allows vRealize Operations Manager to gather
more objects into its inventory for monitoring. Unlike data nodes, remote collector nodes only include the
collector role of vRealize Operations Manager, without storing data or processing any analytics functions.
A remote collector node is usually deployed to navigate rewalls, reduce bandwidth across data centers,
connect to remote data sources, or reduce the load on the vRealize Operations Manager analytics cluster.
Remote collectors do not buer data while the network is experiencing a problem. If the connection between
remote collector and analytics cluster is lost, the remote collector does not store data points that occur
during that time. In turn, and after the connection is restored, vRealize Operations Manager does not
retroactively incorporate associated events from that time into any monitoring or analysis.
You must have at least a master node before adding remote collector nodes.
About vRealize Operations Manager High Availability
vRealize Operations Manager supports high availability (HA). HA creates a replica for the
vRealize Operations Manager master node and protects the analytics cluster against the loss of a node.
With HA, data stored on the master node is always 100% backed up on the replica node. To enable HA, you
must have at least one data node deployed, in addition to the master node.
HA is not a disaster recovery mechanism. HA protects the analytics cluster against the loss of only one
n
node, and because only one loss is supported, you cannot stretch nodes across vSphere clusters in an
aempt to isolate nodes or build failure zones.
When HA is enabled, the replica can take over all functions that the master provides, were the master to
n
fail for any reason. If the master fails, failover to the replica is automatic and requires only two to three
minutes of vRealize Operations Manager downtime to resume operations and restart data collection.
VMware, Inc. 13
vRealize Operations Manager vApp Deployment and Configuration Guide
When a master node problem causes failover, the replica node becomes the master node, and the cluster
runs in degraded mode. To get out of degraded mode, take one of the following steps.
Return to HA mode by correcting the problem with the master node. When a master node exits an
n
HA-enabled cluster, master node does not rejoin with the cluster without manual intervention.
Therefore, restart the vRealize Operations Analytics process on the downed node to change its role
to replica and rejoin the cluster.
Return to HA mode by converting a data node into a new replica node and then removing the old,
n
failed master node. Removed master nodes cannot be repaired and re-added to
vRealize Operations Manager.
Change to non-HA operation by disabling HA and then removing the old, failed master node.
n
Removed master nodes cannot be repaired and re-added to vRealize Operations Manager.
In the administration interface, after an HA replica node takes over and becomes the new master node,
n
you cannot remove the previous, oine master node from the cluster. In addition, the previous node
continues to be listed as a master node. To refresh the display and enable removal of the node, refresh
the browser.
When HA is enabled, the cluster can survive the loss of one data node without losing any data.
n
However, HA protects against the loss of only one node at a time, of any kind, so simultaneously losing
data and master/replica nodes, or two or more data nodes, is not supported. Instead,
vRealize Operations Manager HA provides additional application level data protection to ensure
application level availability.
When HA is enabled, it lowers vRealize Operations Manager capacity and processing by half, because
n
HA creates a redundant copy of data throughout the cluster, as well as the replica backup of the master
node. Consider your potential use of HA when planning the number and size of your
vRealize Operations Manager cluster nodes. See “Sizing the vRealize Operations Manager Cluster,” on
page 9.
When HA is enabled, deploy analytics cluster nodes on separate hosts for redundancy and isolation.
n
One option is to use anti-anity rules that keep nodes on specic hosts in the vSphere cluster.
If you cannot keep the nodes separate, you should not enable HA. A host fault would cause the loss of
more than one node, which is not supported, and all of vRealize Operations Manager would become
unavailable.
The opposite is also true. Without HA, you could keep nodes on the same host, and it would not make a
dierence. Without HA, the loss of even one node would make all of vRealize Operations Manager
unavailable.
When you power o the data node and change the network seings of the VM, this aects the IP
n
address of the data node. After this point, the HA cluster is no longer accessible and all the nodes have
a status of "Waiting for analytics". Verify that you have used a static IP address.
When you remove a node that has one or more vCenter adapters congured to collect data from a HA-
n
enabled cluster, one or more vCenter adapters associated with that node stops collecting. You change
the adapter conguration to pin them to another node before removing the node.
Administration UI shows the resource cache count, which is created for active objects only, but the
n
Inventory Explorer displays all objects. Therefore, when you remove a node from a HA-enabled cluster
allowing the vCenter adapters collect data and rebalance each node, the Inventory explorer displays a
dierent quantity of objects from that shown in the Administration UI.
