Data sources are the products and components that provide performance and configuration data.
The Data Aggregator data source administration is integrated into
Performance Center
.
CA Application Delivery Analysis
,
CA Network Flow Analysis
, and
CA Unified Communications Monitor
collect and aggregate data independently. However, once these data sources are registered in
Performance Center
,
CA Performance Management
controls many administrative functions.
CA Performance Management
does not administer
CA Spectrum
.
Synchronization status is included in the table on the Manage Data Sources page. Failures and detailed statuses are included in the Data Source Log.
The System Health icon at the top of the page indicates when a synchronization failure occurs. To view more information about the failure, click the icon. Review the information in the Global Synchronization Status section and the Data Sources section. For more information, see Synchronize Data Sources.

Configuration Data from Data Sources
For
CA Application Delivery Analysis
,
CA Network Flow Analysis
, and
CA Unified Communications Monitor
, the monitoring parameters, user accounts, and other definitions are shared with
CA Performance Management
and other registered data sources after registration.
During registration,
CA Performance Management
imports shared monitoring data, such as user accounts, SNMP profiles, and other administrative data from the data sources.
CA Performance Management
resolves conflicts and eliminates duplication. At the next synchronization,
CA Performance Management
sends updated administrative data to registered data sources.
The registration process includes a "binding" step that prevents further modifications to shared administrative data in individual data sources. As a result, the data source administrator can only modify shared monitoring parameters after registration.
For user accounts and SNMP profiles,
Performance Center
uses the following processes to handle conflicts or duplicates:

Redundant User Accounts
A user can have two different accounts with the same name in different data source products. The resulting user account retains the password of the first account that is synchronized. The unique role rights and permissions from other accounts are added to the account as you register more data sources.
While multiple user accounts sometimes share a username in different data sources, some account parameters differ. Manual editing is required in this situation.
Example
A user who is named Robert uses
CA Network Flow Analysis
, and a different user, also named Robert, uses
CA Application Delivery Analysis
. In this case,
CA Performance Management
creates one account that is named Robert. The role rights and permissions from both data sources are merged into a single new account. To preserve the distinct role rights of the two accounts, create an account with a unique username.
Redundant SNMP Profiles
Registering a data source that contains SNMP profile definitions automatically adds the profiles to
CA Performance Management
. The profiles are distributed to the other registered data sources during the next synchronization.
When a data source is added,
CA Performance Management
minimizes duplication of SNMP profiles by comparing the following values to existing profiles:
  • User for SNMPv3
  • Community String for SNMPv1 and SNMPv2
If the compared values match, the SNMP profile with the most recent timestamp is retained.
If the compared values do not match,
CA Performance Management
appends a number to duplicate profile names. For example, the first profile that is named Boston remains Boston. The second profile becomes Boston(1).
Synchronization with
CA Spectrum
After an integration with
CA Spectrum
is configured, consider the following guideline whenever you restore the SpectroSERVER or OneClick database:
  • If
    CA Spectrum
    exists as a data source in
    Performance Center
    , whenever you restore another data source, restart Tomcat.
You must follow the correct procedures to enable data to synchronize correctly between
CA Spectrum
and
Performance Center
. For the correct procedures, see Integrate CA Spectrum with CA Performance Management .
