When you install vRealize Operations Manager, you use a vRealize Operations Manager vApp deployment, Linux installer, or Windows installer to create role-less nodes. After the nodes are created and have their names and IP addresses, you use an administration interface to congure 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.

The following node types make up the vRealize Operations Manager analytics cluster:

Master 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.

Data Node

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.

Replica Node

To use vRealize Operations Manager high availability (HA), the cluster requires that you convert a data node into a replica of the master node.

The following node type is a member of the vRealize Operations Manager cluster but not part of the analytics cluster:

Remote Collector 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 dierent operating system than the rest of the cluster.

VMware, Inc. 11

vRealize Operations Manager Installation and Configuration Guide for Linux and Windows

General vRealize Operations Manager Cluster Node Requirements

When you create the cluster nodes that make up vRealize Operations Manager, you have general requirements that you must meet.

General Requirements

vRealize Operations Manager Version. All nodes must run the same vRealize Operations Manager

version.

For example, do not add a version 6.1 data node to a cluster of vRealize Operations Manager 6.2 nodes.

Analytics Cluster Deployment Type. In the analytics cluster, all nodes must be the same kind of

deployment: vApp, Linux, or Windows.

Do not mix vApp, Linux, and Windows nodes in the same analytics cluster.

Remote Collector Deployment Type. A remote collector node does not need to be the same deployment

type as the analytics cluster nodes.

When you add a remote collector of a dierent deployment type, the following combinations are supported:

vApp analytics cluster and Windows remote collector

Linux analytics cluster and Windows remote collector

Analytics Cluster Node Sizing. In the analytics cluster, CPU, memory, and disk size must be identical

for all nodes.

Master, replica, and data nodes must be uniform in sizing.

Remote Collector Node Sizing. Remote collector nodes may be of dierent sizes from each other or

from the uniform analytics cluster node size.

Geographical Proximity. You may place analytics cluster nodes in dierent vSphere clusters, but the

nodes must reside in the same geographical location.

Dierent geographical locations are not supported.

Virtual Machine Maintenance. When any node is a virtual machine, you may only update the virtual

machine software by directly updating the vRealize Operations Manager software.

For example, going outside of vRealize Operations Manager to access vSphere to update VMware Tools is not supported.

Redundancy and Isolation. If you expect to enable HA, place analytics cluster nodes on separate hosts.

See “About vRealize Operations Manager High Availability,” on page 33.

Requirements for Solutions

Be aware that solutions might have requirements beyond those for vRealize Operations Manager itself. For example, vRealize Operations Manager for Horizon View has specic sizing guidelines for its remote collectors.

See your solution documentation, and verify any additional requirements before installing solutions. Note that the terms solution, management pack, adapter, and plug-in are used somewhat interchangeably.

Chapter 1 Preparing for vRealize Operations Manager Installation

vRealize Operations Manager Cluster Node Networking Requirements

When you create the cluster nodes that make up vRealize Operations Manager, the associated setup within your network environment is critical to inter-node communication and proper operation.

Networking Requirements

I vRealize Operations Manager analytics cluster nodes need frequent communication with one another. In general, your underlying vSphere architecture might create conditions where some vSphere actions aect that communication. Examples include, but are not limited to, vMotions, storage vMotions, HA events, and DRS events.

The master and replica nodes must be addressed by static IP address, or fully qualied domain name

(FQDN) with a static IP address.

Data and remote collector nodes may use dynamic host control protocol (DHCP).

You must be able to successfully reverse-DNS all nodes, including remote collectors, to their FQDN,

currently the node hostname.

Nodes deployed by OVF have their hostnames set to the retrieved FQDN by default.

All nodes, including remote collectors, must be bidirectionally routable by IP address or FQDN.

Analytics cluster nodes must not be separated by network address translation (NAT), load balancer,

rewall, or a proxy that inhibits bidirectional communication by IP address or FQDN.

Analytics cluster nodes must not have the same hostname.

Place analytics cluster nodes within the same data center and connect them to the same local area

network (LAN).

Place analytics cluster nodes on same Layer 2 network and IP subnet.

A stretched Layer 2 or routed Layer 3 network is not supported.

Do not span the Layer 2 network across sites, which might create network partitions or network

performance issues.

One-way latency between analytics cluster nodes must be 5 ms or lower.

Network bandwidth between analytics cluster nodes must be 1 gbps or higher.

Do not distribute analytics cluster nodes over a wide area network (WAN).

To collect data from a WAN, a remote or separate data center, or a dierent geographic location, use remote collectors.

Remote collectors are supported through a routed network but not through NAT.

vRealize Operations Manager Cluster Node Best Practices

When you create the cluster nodes that make up vRealize Operations Manager, additional best practices improve performance and reliability in vRealize Operations Manager.

Best Practices

Deploy vRealize Operations Manager analytics cluster nodes in the same vSphere cluster.

VMware, Inc. 13

vRealize Operations Manager Installation and Configuration Guide for Linux and Windows

If you deploy analytics cluster nodes in a highly consolidated vSphere cluster, you might need resource

reservations for optimal performance.

Determine whether the virtual to physical CPU ratio is aecting performance by reviewing CPU ready time and co-stop.

Deploy analytics cluster nodes on the same type of storage tier.

To continue to meet analytics cluster node size and performance requirements, apply storage DRS anti-

anity rules so that nodes are on separate datastores.

To prevent unintentional migration of nodes, set storage DRS to manual.

To ensure balanced performance from analytics cluster nodes, use ESXi hosts with the same processor

frequencies. Mixed frequencies and physical core counts might aect analytics cluster performance.

To avoid a performance decrease, vRealize Operations Manager analytics cluster nodes need

guaranteed resources when running at scale. The vRealize Operations Manager Knowledge Base includes sizing spreadsheets that calculate resources based on the number of objects and metrics that you expect to monitor, use of HA, and so on. When sizing, it is beer to over-allocate than underallocate resources.

See Knowledge Base article 2093783.

Because nodes might change roles, avoid machine names such as Master, Data, Replica, and so on.

Examples of changed roles might include making a data node into a replica for HA, or having a replica take over the master node role.

The NUMA placement is removed in the vRealize Operations Manager 6.3 and later. Procedures related

N To ensure the availability of adequate resources and continued product performance, monitor vRealize Operations performance by checking its CPU usage, CPU ready and CPU contention time.

Using IPv6 with vRealize Operations Manager

vRealize Operations Manager supports Internet Protocol version 6 (IPv6), the network addressing convention that will eventually replace IPv4. Use of IPv6 with vRealize Operations Manager requires that certain limitations be observed.

Using IPv6

All vRealize Operations Manager cluster nodes, including remote collectors, must have IPv6 addresses.

Do not mix IPv6 and IPv4.

14 VMware, Inc.

Chapter 1 Preparing for vRealize Operations Manager Installation

All vRealize Operations Manager cluster nodes, including remote collectors, must be vApp or Linux

based. vRealize Operations Manager for Windows does not support IPv6.

Use global IPv6 addresses only. Link-local addresses are not supported.

If any nodes use DHCP, your DHCP server must be congured to support IPv6.

DHCP is only supported on data nodes and remote collectors. Master nodes and replica nodes still

require xed addresses, which is true for IPv4 as well.

Your DNS server must be congured to support IPv6.

When adding nodes to the cluster, remember to enter the IPv6 address of the master node.

When registering a VMware vCenter® instance within vRealize Operations Manager, place square

brackets around the IPv6 address of your VMware vCenter Server® system if vCenter is also using IPv6.

For example: [2015:0db8:85a3:0042:1000:8a2e:0360:7334]

Note that, even when vRealize Operations Manager is using IPv6, vCenter Server may still have an IPv4 address. In that case, vRealize Operations Manager does not need the square brackets.

You cannot register an Endpoint Operations Management agent in an environment that supports both

IPv4 and IPv6. In the event that you aempt to do so, the following error appears:

Connection failed. Server may be down (or wrong IP/port were used). Waiting for 10 seconds

before retrying.

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 dicult 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 specic 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 congure a vRealize Operations Manager node.

2 Deploy a temporary vRealize Operations Manager node.

3 Congure 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 dierent 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.

VMware, Inc. 15

vRealize Operations Manager Installation and Configuration Guide for Linux and Windows

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 notication when thresholds are passed.

Add Data Disk Space to a vRealize Operations Manager Linux or Windows Node

You add to the data disk of vRealize Operations Manager Linux or Windows nodes when space for storing the collected data runs low.

The following example is for a Linux system. The Windows process is similar, but with Windows characteristics such as backward slashes instead of forward slashes.

Prerequisites

Note the disk size of the analytics cluster nodes. When adding disk, you must maintain uniform size across analytics cluster nodes.

Procedure

1 Add a new disk to the system, and partition and format the disk as needed.

2 Use the vRealize Operations Manager administration interface to take the cluster oine.

3 Stop the vmware-casa service.

4 Move the contents of /storage/db into a directory on the new disk.

5 Create a symbolic link from the new directory back to /storage/db, so that /storage/db now references

the new disk.

6 Start the vmware-casa service.

7 Bring the cluster online.

Custom vRealize Operations Manager Certificates

By default, vRealize Operations Manager includes its own authentication certicates. The default certicates cause the browser to display a warning when you connect to the vRealize Operations Manager user interface.

Your site security policies might require that you use another certicate, or you might want to avoid the warnings caused by the default certicates. In either case, vRealize Operations Manager supports the use of your own custom certicate. You can upload your custom certicate during initial master node conguration or later.

Custom vRealize Operations Manager Certificate Requirements

A certicate used with vRealize Operations Manager must conform to certain requirements. Using a custom certicate is optional and does not aect vRealize Operations Manager features.

Requirements for Custom Certificates

Custom vRealize Operations Manager certicates must meet the following requirements.

The certicate le must include the terminal (leaf) server certicate, a private key, and all issuing

certicates if the certicate is signed by a chain of other certicates.

In the le, the leaf certicate must be rst in the order of certicates. After the leaf certicate, the order

does not maer.

In the le, all certicates and the private key must be in PEM format. vRealize Operations Manager

does not support certicates in PFX, PKCS12, PKCS7, or other formats.

16 VMware, Inc.

Chapter 1 Preparing for vRealize Operations Manager Installation

In the le, all certicates and the private key must be PEM-encoded. vRealize Operations Manager does

not support DER-encoded certicates or private keys.

PEM-encoding is base-64 ASCII and contains legible BEGIN and END markers, while DER is a binary format. Also, le extension might not match encoding. For example, a generic .cer extension might be used with PEM or DER. To verify encoding format, examine a certicate le using a text editor.

The le extension must be .pem.

The private key must be generated by the RSA or DSA algorithm.

The private key must not be encrypted by a pass phrase if you use the master node conguration

wizard or the administration interface to upload the certicate.

The REST API in this vRealize Operations Manager release supports private keys that are encrypted by

a pass phrase. Contact VMware Technical Support for details.

The vRealize Operations Manager Web server on all nodes will have the same certicate le, so it must

be valid for all nodes. One way to make the certicate valid for multiple addresses is with multiple Subject Alternative Name (SAN) entries.

SHA1 certicates creates browser compatibility issues. Therefore, ensure that all certicates that are

created and being uploaded to vRealize Operations Manager are signed using SHA2 or newer.

Sample Contents of Custom vRealize Operations Manager Certificates

For troubleshooting purposes, you can open a custom certicate le in a text editor and inspect its contents.

PEM Format Certificate Files

A typical PEM format certicate le resembles the following sample.

Chapter 1 Preparing for vRealize Operations Manager Installation

Create a Node by Running the vRealize Operations Manager Linux Installer

vRealize Operations Manager consists of one or more nodes, in a cluster. To create nodes, you download and run the vRealize Operations Manager Enterprise installer for Linux.

Prerequisites

Plan to use the system only as a vRealize Operations Manager node. Do not host other applications on

the same machine.

Verify that vRealize Operations Manager ports are open at the rewall. See “How vRealize Operations

Manager Uses Network Ports,” on page 19.

Verify that prerequisite packages are installed. See “Required Linux Packages for vRealize Operations

Manager,” on page 21.

If this node is to be the master node, reserve a static IP address for the virtual machine, and know the

associated domain name server, default gateway, and network mask values.

Plan to keep the IP address because it is dicult to change the address after installation.

If this node is to be a data node that will become the HA replica node, reserve a static IP address for the

virtual machine, and know the associated domain name server, default gateway, and network mask values.

Plan to keep the IP address because it is dicult to change the address after installation.

In addition, familiarize yourself with HA node placement as described in “About vRealize Operations

Manager High Availability,” on page 33.

Preplan your domain and machine naming so that the Linux machine name will begin and end with

alphabet (a–z) or digit (0–9) characters, and will only contain alphabet, digit, or hyphen (-) characters. The underscore character (_) must not appear in the host name or anywhere in the fully qualied domain name (FQDN).

Plan to keep the name because it is dicult to change the name after installation.

For more information, review the host name specications from the Internet Engineering Task Force. See www.ietf.org.

Preplan node placement and networking to meet the requirements described in “General vRealize

Operations Manager Cluster Node Requirements,” on page 12 and “vRealize Operations Manager Cluster Node Networking Requirements,” on page 13.

If you expect the vRealize Operations Manager cluster to use IPv6 addresses, review the IPv6

limitations described in “Using IPv6 with vRealize Operations Manager,” on page 14.

Be aware that vRealize Operations Manager uninstalls httpd if it is installed, because

vRealize Operations Manager installs its version of Apache.

If vRealize Operations Manager uninstalls httpd, it backs up the /etc/httpd conguration directory.

Uninstall any existing copies of PostgreSQL, and remove PostgreSQL directories and data.

vRealize Operations Manager must install its own copy of PostgreSQL.

Verify that all machines in the le ntp.conf are resolvable. If you are unsure about the contents of

ntp.conf, make a backup copy of the le, and overwrite the original with the default version from a

new machine installation.

Locate your copy of the vRealize Operations Manager Enterprise bin installer for Linux.

Creating the vRealize Operations Manager Master

Node 2

All vRealize Operations Manager installations require a master node.

This chapter includes the following topics:

“About the vRealize Operations Manager Master Node,” on page 29

“Run the Setup Wizard to Create the Master Node,” on page 29

About the vRealize Operations Manager Master Node

The master node is the required, initial node in your vRealize Operations Manager cluster.

In single-node clusters, administration and data are on the same master node. A multiple-node cluster includes one master node and one or more data nodes. In addition, there might be remote collector nodes, and there might be one replica node used for high availability.

The master node performs administration for the cluster and must be online before you congure any new nodes. In addition, the master node must be online before other nodes are brought online. If the master node and replica node go oine together, bring them back online separately. Bring the master node completely online rst, and then bring the replica node online. For example, if the entire cluster were oine for any reason, you would bring the master node online rst.

Creating the Master Node (hp://link.brightcove.com/services/player/bcpid2296383276001?

bctid=ref:video_vrops_create_master_node)

Run the Setup Wizard to Create the Master Node

All vRealize Operations Manager installations require a master node. With a single node cluster, administration and data functions are on the same master node. A multiple-node vRealize Operations Manager cluster contains one master node and one or more nodes for handling additional data.

Prerequisites

Create a node by running the vRealize Operations Manager Enterprise installer for Linux or Windows.

After it is deployed, note the fully qualied domain name (FQDN) or IP address of the node.

If you plan to use a custom authentication certicate, verify that your certicate le meets the

requirements for vRealize Operations Manager. See “Custom vRealize Operations Manager

Certicates,” on page 16.

VMware, Inc.

vRealize Operations Manager Installation and Configuration Guide for Linux and Windows
