Manage Data Sources

Data sources are the products and components that provide performance and configuration data.

Data sources are the products and components that provide performance and configuration data in
NetOps Portal
. Data aggregator data source administration is integrated into
DX NetOps Performance Management
.
CA Application Delivery Analysis
,
Network Flow Analysis
, and
CA Unified Communications Monitor
collect and aggregate data independently. However, after you have registered these data sources in
DX NetOps Performance Management
,
DX NetOps Performance Management
controls many administrative functions.
DX NetOps Performance Management
does not administrate
DX NetOps Spectrum
.

Configuration Data from Data Sources
Register
CA Application Delivery Analysis
,
Network Flow Analysis
, and
CA Unified Communications Monitor
as data sources in
DX NetOps Performance Management
to share the monitoring parameters, user accounts, and other definitions with
DX NetOps Performance Management
and other registered data sources. During registration,
DX NetOps Performance Management
imports shared monitoring data, such as user accounts, SNMP profiles, and other administrative data from these data sources.
DX NetOps Performance Management
resolves conflicts and eliminates duplication. At the next synchronization,
DX NetOps 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.
Conflict or Duplicate Handling
For user accounts and SNMP profiles,
DX NetOps Performance Management
uses the following processes to handle conflicts or duplicates:
3
Redundant User Accounts
Users can have two different accounts with the same name in different data sources. 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. You must edit these account parameters.
Example
A user named Robert uses
Network Flow Analysis
, and a different user, also named Robert, uses
CA Application Delivery Analysis
. In this case,
DX NetOps Performance Management
creates one account that is named Robert.
DX NetOps Performance Management
merges the role rights and permissions from both data sources 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
DX NetOps Performance Management
. The profiles are distributed to the other registered data sources during the next synchronization.
When a data source is added,
DX NetOps 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,
DX NetOps Performance Management
retains the SNMP profile with the most recent timestamp.
If the compared values do not match,
DX NetOps 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).
