In a virtualized infrastructure or cloud infrastructure, existing methods for tracking applications are

not accurate or scalable. Virtual infrastructure administrators use their own naming conventions,

spreadsheets, folder templates and notes.

Information is dispersed in many different places and not kept up to date, except with tribalknowledge. This outlines a great need for a more accurate and updated view of application

dependencies across the virtual infrastructure. The information must be up-to-date, accurate and

seamlessly available with virtual infrastructure management solutions for day-to-day operational

use.


4/25

Utilizing its pre-built knowledge base, vCenter Infrastructure Navigator automatically discovers

applications, services, relationships and dependencies to build maps that yield a detailed overview

into the virtual infrastructure.

vCenter Infrastructure Navigator integrates with VMware vCenter Site Recovery Manager toshowcase existing disaster recovery (DR) protection, and effectively ensures higher applications

delivery service levels.


5/25

vCenter Infrastructure Navigator automatically discovers application services and visualizes

relationships and maps, dependencies of applications on virtualized compute, storage and network

resources.

Administrators can search and visualize applications and application services within VMware vCenterServer in their daily operations.

vCenter Infrastructure Navigator is seamlessly integrated into the vSphere Web Client and

complements vCenter Operations Manager. It generates dependency maps and tabular

presentations with overlays for Site Recovery Manager, vApps and so on.

It eases the process in triage, backup and recovery, HA planning, change impact and vAppdefinitions.

vCenter Infrastructure Navigator provides automated discovery and dependency mapping. It is

characterized by the fact that it is simple to download and deploy, and its rapid discovery and

dependency mapping capability. It does not require VMware Professional Services to install.

It is self downloadable and is also available for trial evaluation. vCenter Infrastructure Navigator

includes an out-of-the-box knowledge base which will continue to be updated.

Beyond the out-of-the-box knowledge base, vCenter Infrastructure Navigator provides the ability to

create manual application mappings to visualize non-linear dependencies, either between virtual

machines or specific services.

vCenter Infrastructure Navigator provides integrated application dependencies in a day-to-day

operational interface.

Infrastructure Navigator seamlessly integrates in the vSphere Web Client user interface. The virtual

machine topology is obtained from vCenter and is updated every 5 minutes. Application discovery

and dependency mapping are kept current to within every hour and presented through the vCenter

user interface.

In vCenter Infrastructure Navigator, search and filter is a short way to identify the right object,

perfect for day-to-day operating. vCenter Infrastructure Navigator offers summary application

portlets that allow you to obtain application services and dependency summaries. This is integrated

into the vCenter interface as an additional port-let along with other vCenter metrics. vCenter

Infrastructure Navigator has Dependency maps, a Topology map that provides visualization of

applications, app services across the virtual infrastructure.

In addition, vCenter Infrastructure Navigator overlays relevant vCenter Server information (such asSite Recovery Manager Protection group, recovery plan, vApp, HA cluster information and so on). It

has Tabular views that provide visibility into virtual machines associated at any level of the virtual

infrastructure: site, clusters, hosts, datastore, or vNetwork. Virtual machine Tabular views include

residing application services and other virtual machine relevant metrics.

Powerful filtering and search capabilities identify virtual machines associated with specific

application criteria.

vCenter Infrastructure Navigator provides the ability to export the data into other applications.

vCenter Infrastructure Navigator is integrated into the vSphere Web Client summary view. When an

object is selected in the inventory tree, infrastructure information is shown in its own information

pane, summarizing discovery status, services and dependencies of the selected object.


8/25

The Application Dependencies subtab below the Manage tab gives you a detailed view of the

selected object. Using the Map view, you can understand the selected objects dependencies

intuitively and even get more information about dependent objects. You can also switch to a table

view, making it easier to find the desired information in large maps.


9/25

Using vCenter Infrastructure Navigator in combination with vCenter Site Recovery Manager allows

the administrator to create SRM protection groups and recovery plans with accurate app visibility.

Workload dependency maps across virtual infrastructure hosts and clusters allow for HA clusters tobe built and set affinity or anti-affinity rules in the virtual environment.

The automated mapping of application services of vCenter Infrastructure Navigator to underlying

virtual machines, enables the administrator to set up judicious configuration of priorities and

dependencies for correct start up sequences.

In this case, the start sequence is as follows:

First , the Master Database starts, after which the Database and Exchange server start

simultaneously.

Than the Application Server One starts first, followed by Application Server 2 after first started up

successfully.

The two Apache servers and the Mail Sync server start in unison and than all desktops start

together.


10/25

vCenter Infrastructure Navigator provides the administrator with the complete application context

as a basis for defining vApps.

All dependencies across all tiers are factored in, including centralized services such AD/ LDAP or DNS.

vCenter Infrastructure Navigator shows dependency drifts, so vApp memberships are kept up to

date and provides a common vocabulary for infrastructure and application teams. Instant and

accurate identification of the applications associated virtual machines allow an easy creation of

vApps.


11/25

vCenter Infrastructure Navigator is integrated in the vCenter Operations Management Suite

Advanced and Enterprise Edition. It is not available as an a-la-carte option.

Please take a moment to review the packaging and pricing overview before we continue.


12/25

Summarizing the value proposition, vCenter Infrastructure Navigator can add value for a number of

use cases and solutions.

In vCenter Operations Manager, vCenter Infrastructure Navigator provides a common language andcontextadministrators can triage for actual and potential issues, change application and business

impacts and become proactive in planning of resources to meet virtual infrastructure delivery SLAs.

With Site Recovery Manager, administrators can plan and maintain accurate disaster recovery plans

based on automated and actual application dependencies. They can factor in changes in application

and virtual machine topology as well dependencies to centralized services and close by physical

servers.

vCenter Infrastructure Navigator improves High Availability and Disaster Recovery planning and set-

up by utilizing vApp context to build HA clusters, affinity rules and placement constraints.


13/25

Next, we will discuss the architecture of vCenter Infrastructure Navigator.

This slide illustrates various components of vCenter Infrastructure Navigator and their dependencies.

vCenter Infrastructure Navigator is a virtual appliance that you can import into VMware vCenter

Server. A virtual appliance is a virtual machine image that contains software designed to run in a

virtual machine, pre-packaged for low maintenance effort and easy deployment.


14/25

With the components of vCenter Infrastructure Navigator, you can map services running in your

virtual environment, examine the application discovery status, view and analyze the dependency

map and have a centralized overview of the entire application environment.

The components of vCenter Infrastructure Navigator are the service, the database and the plug-in

for the vSphere Web Client.

The server component receives data from the Active Discovery component and reconciles data

before transferring it to the database.

The database component stores the data received from the server component. The database

component also stores Infrastructure Navigator configurations. vCenter Infrastructure Navigator

does not support storing of data in an external database.

The vCenter Infrastructure Navigator plug-in in the vSphere Web Client provides a graphical user

interface that you can use to view and analyze dependencies.


15/25

The vCenter Infrastructure Navigator virtual appliance interacts with vSphere as follows.

The vApp

Registers with the vCenter Server,

Installs a plug-in for the vSphere Web Client,

Leverages the vCenter inventory to determine which virtual machines will be probed, and

Probes virtual machines with supported operating systems that are running compatible versions of

VMware Tools.

Results from the discovery performed by vCenter Infrastructure Navigator can be viewed in the

vSphere Web Client, although not in the standard vSphere Client. Through the integration with SiteRecovery Manager, information about protection group membership can be seen at a glance while

viewing application group memberships.


16/25

Next, we will talk about the methodology behind vCenter Infrastructure Navigator.

vCenter Infrastructure Navigator uses Active Discovery to access the virtual machines. Active

discovery is a multithreaded process that uses VMware Tools to access virtual machines.


17/25

The application mapping process starts immediately after installation, provided you have valid

administrator-level vCenter Server credentials.

vCenter Infrastructure Navigator maps continuously, unless you stop or disable vCenter

Infrastructure Navigator.

The system begins to populate the inventory table immediately after the virtual appliance has been

installed and configured.

If configuration mapping is incomplete, a This VM is pending application mapping message is

displayed in place of the dependency map.

The vCenter Infrastructure Navigator can remotely connect to the VMware Tools to run command

prompts and netstat. This works with the extension in VMware Tools that implements the VIX API as

well.

vCenter Infrastructure Navigator does not need additional credentials to login and access guest

operating systems.

vCenter Infrastructure Navigator supports fingerprints, used to match application services and look

inside file systems, Windows registries and to run commands such as WMIC. It allows vCenter

Infrastructure Navigator to not only access a list of running processes, but to look into program file

folders and check what is installed and in which version.


18/25

vCenter Infrastructure Navigator leverages netstat to obtain dependencies and check which

processes are running on ports, which TCP connections are open against open IPs, or to run netstat

on both virtual machines to match dependencies.

Application services are re-mapped at predefined time intervals (default is 1 hour). This ensures that

the vCenter Infrastructure Navigator database is up-to-date and is synchronized with changes in the

virtual environment. The result of the most recent mapping is shown in the Successful Discovery

field.

vCenter Server details are refreshed every five minutes to detect any changes in the virtual

environment. For example, if a virtual machine is powered off, it will be shown in the Discovery

status field.


19/25

vCenter Infrastructure Navigator only maps services that run on virtual machines if the following

conditions are met:

The virtual machine is powered on.

The virtual machine can be reached on the network.

The vCenter credentials are valid.

The virtual machine is running on a supported ESX version.

VMware Tools is installed and running on the virtual machine.

The VMware Tools version is supported by Infrastructure Navigator.

And the virtual machine has a supported guest operating system on it.

If any one of these condition fails, an Access failed error message is displayed in the Discovery status

field.


20/25

Features such as how to define multi-tier applications, will be discussed in more detail in module 3

of this course. The applications defined by vCenter Infrastructure Navigator are shown in vCenter

Operations Manager under the Groups tab to monitor the Health, Risk and Efficiency for these

specific applications. You can export the maps as images or .csv files, which then can be imported

into Excel.

Next, we will discuss the system requirements to run vCenter Infrastructure Navigator.


21/25

The ports listed on this slide are needed by the different components of vCenter Infrastructure

Navigator.

You must meet certain software requirements before proceeding with the deployment of vCenter

Infrastructure Navigator virtual appliance.


22/25

vCenter Infrastructure Navigator supports discovery of virtual machines and applications on the

following ESX/ ESXi versions:

Version 3.5, 4.0, 4.1 and 5.x

Target virtual machines must have a supported version of VMware tools installed for the respective

ESX versions, and should use virtual hardware version 4 or above.

Target virtual machines may not be running an unsupported operating system or run without

VMware Tools installed. This slide shows a list of unsupported operating systems.

vCenter Infrastructure Navigator does not support virtual machines with guest operating system

defined during creation as Other (64-bit) and Other (32-bit).


23/25

You must meet certain requirements before you start deploying the Infrastructure Navigator in a

virtual appliance on the vSphere Client.

The appliance must have 2vCPUs with 4GHz total, 4GB of memory, 20GB of free disk space and a

1Gbps Network interface. Also, the vCenter Infrastructure Navigator server component and vCenterServer 5.x need to be installed. The vSphere Web Client 5.1 needs to be registered to the vCenter

Server.


24/25

To access vCenter Infrastructure Navigator through the vSphere Web Client, your client must meet

the requirements outlined in this slide.

This concludes Module 1.
