vApp Components
vCenter Operations Manager architecture consists of two virtual machines. The following section describes
the vCenter Operations Manager key components of the vApp Architecture.
UI VM
The UI VM allows you to access the results of the analytics in the form of badges and scores using the Web-
based application for the UI VM. It also allows you access to the Administration Portal in order to perform
management tasks. The applications in UI VM are described as follows:
vSphere Web
Application
The vCenter Operations Manager vSphere UI provides a summary and deeper
views into the vSphere environment.
Enterprise Web
Application
The vCenter Operations Manager Enterprise application provides a
customizable Web-based user interface. It is available using the Enterprise
edition and provides a view into the entire enterprise.
Administration Web
Application
The vCenter Operations Manager Administration Portal provides a user
interface for vCenter Operations Manager maintenance and management
tasks.
Analytics VM
The Analytics VM is responsible for collecting data from vCenter Server, vCenter Configuration Manager, and
third party data sources, such as metrics, topology, and change events. Raw data is stored in its scalable File
System Database (FSDB). The components in Analytics VM are described as follows:
Capacity and
Performance Analytics
Checks the incoming metrics for abnormalities in real time, updates health
scores, and generates alerts when necessary.
Capacity Collector
Collects metrics and computes derived metrics.
FileSystem Database
Stores the collected metrics statistics.
Postgres DB
Stores all other data collected, including objects, relationships, events, dynamic
thresholds, and alerts.
vCenter Operations Manager and vCenter Server Connections
A single vCenter Operations Manager server can connect to one or to multiple vCenter Server instances. All
communications between vCenter Operations Manager and vCenter Server take place over an SSL connection
and are authenticated by public key certificates or stored certificates.
When vCenter Operations Manager is connected to multiple vCenter Server instances, you have a common
view across all vCenter Server instances for all reporting features.
Basic Deployment
A basic deployment connects vCenter Operations Manager to a single vCenter Server.
