About vCenter CapacityIQ 1
VMware vCenter™ CapacityIQ helps vSphere system administrators monitor and manage the capacity of
virtualized environments.
Install CapacityIQ as a vCenter Server plug-in. CapacityIQ ensures that virtualized infrastructure capacity is
efficient and predictable.
The what-if scenario feature allows administrators to model changes to the virtualized environment and assess
the effect of a change without implementation costs or time-consuming trial and error.
This chapter includes the following topics:
n“CapacityIQ Main Tasks,” on page 7
n“CapacityIQ Architecture,” on page 7
n“Administrator Process Overview for CapacityIQ,” on page 9
n“Licensing CapacityIQ,” on page 9
CapacityIQ Main Tasks
CapacityIQ collects performance information about managed objects, such as hosts and virtual machines in
the virtual infrastructure. CapacityIQ stores the information in the CapacityIQ database.
You query the database to understand available capacity in the virtual infrastructure. CapacityIQ performs
these tasks.
nCollects performance statistics about managed objects in the virtual infrastructure.
nStores the statistics in the CapacityIQ database and builds a performance history for each object.
nCollects and stores inventory history for each object, such as moving a virtual machine from one host to
another.
nRetrieves and presents the statistics on demand through the CapacityIQ user interface.
nFilters the information presented according to objects, time periods, or types of activity.
nProvides scenarios to model potential changes to the virtual infrastructure.
CapacityIQ Architecture
CapacityIQ is a virtual appliance that you install on vCenter Server. A virtual appliance is a virtual machine
image that contains software designed to run in a virtual machine.
CapacityIQ does not affect the performance of vSphere. The CapacityIQ virtual appliance processes the vCenter
Server data.
VMware, Inc. 7
You must have one vCenter Server instance for each CapacityIQ instance. If you have vCenter Server Linked
Mode groups in your environment, install a separate instance of CapacityIQ for each vCenter Server system.
The virtual appliance includes the following components as illustrated in Figure 1-1.
CapacityIQ
Administrative Server
The CapacityIQ administrative server provides the Administration Portal user
interface for the CapacityIQ system administrator to configure and maintain
the virtual appliance.
CapacityIQ Server The CapacityIQ server hosts an operating system and the CapacityIQ
application. A monitoring feature called watchdog tracks whether CapacityIQ
processes are operating properly. The watchdog logs exceptions such as
services stopping and starting. Events are posted in the ciq_watchdog.log file.
Database Server The CapacityIQ virtual appliance includes its own PostgreSQL database. The
database server stores data collected from objects managed in vCenter Server.
NOTE CapacityIQ does not support storing data in an external database.
Data Collector The data collector collects inventory and performance data. Configure the data
collector to access vCenter Server through port 443 on vCenter Server.
Each instance of the vSphere Client installed on vCenter Server can use CapacityIQ. CapacityIQ does not
require changes to your vCenter Server setup, such as modifying the logging levels.

CapacityIQ begins collecting performance data shortly after installation. Updates to performance statistics in
the CapacityIQ database occur using standard vSphere APIs. Data collection remains continuous unless you
stop CapacityIQ.
CapacityIQ begins to populate the dashboard within an hour or so after you install the virtual appliance. To
generate meaningful information in views and reports, wait until you have collected at least three days of
performance data.

Administrator Process Overview for CapacityIQ
The person administering CapacityIQ is responsible for installation, maintenance, and troubleshooting.
Setup
The initial setup includes the following tasks.
1 In the vSphere Client, import the CapacityIQ appliance.
2 Deploy the CapacityIQ appliance, which means that CapacityIQ completes an initialization sequence. This
process includes entering account credentials for the virtual appliance services and CapacityIQ
Administration Portal access.
3 Configure the network and time zone settings.
4 Open a browser and log in to the CapacityIQ Administration Portal.
5 Configure the settings to register CapacityIQ with vCenter Server.
6 Apply the CapacityIQ license.
7 Verify that CapacityIQ populates the dashboard with data.
The process of populating the dashboard might take a few hours.
If you already have an instance of CapacityIQ installed, you can update the virtual appliance to the latest
release.
Maintenance
After initial setup is complete, perform ongoing administrator tasks.
nStop or restart CapacityIQ, for example, during a vCenter Server maintenance cycle.
nCheck the status of CapacityIQ on the Status tab in the Administration Portal.
nApply patches and updates to the CapacityIQ application.
nManage license changes and renewals.
nTroubleshoot any problems and send diagnostic data to VMware technical support.
Licensing CapacityIQ
CapacityIQ supports license management through vCenter Server or through the CapacityIQ Administration
Portal depending on the license type and version of vCenter Server that CapacityIQ is registered to.
CPU Licenses for CapacityIQ
The Administration Portal supports the management of only CPU-based licenses for CapacityIQ. If you have
an existing CPU-based license, it will continue to function with vCenter Server 4.1.
Virtual Machine Licenses for CapacityIQ
If you obtain a virtual machine-based license for CapacityIQ, install and manage the license from
vCenter Server. Virtual machine-based licenses for CapacityIQ require vCenter Server 4.1 or later versions. For
information about assigning license keys to assets in vCenter Server, see the VMware vSphere documentation.

Evaluation and Full Licenses
You can download a free evaluation version of CapacityIQ that offers a trial period. For more information
about licensing, see the VMware licensing portal.
