CA Spectrum - CA Performance Management integration lets you share models, Global Collections, and events between two powerful infrastructure management systems.
 The integration can be done between a single instance of CA Spectrum and a single instance of CA Performance Management. You cannot integrate one instance of CA Spectrum with multiple instances of CA Performance Management.
The CA Spectrum data source contributes the following item types to CA Performance Management:
  • Devices
  • Interfaces
  • Groups
CA Spectrum also retrieves and displays infrastructure performance events from the CA Performance Management Event Manager. As a result, you can see performance and fault alarms side-by-side in OneClick.
CA Performance Management retrieves devices from CA Spectrum to extend the CA Performance Management device Inventory. You can determine which devices are retrieved. The interfaces that are associated with each device are added to the Inventory automatically; however, they are subject to CA Infrastructure Management Data Aggregator interface filtering.
CA Performance Management IP domains are synchronized and displayed in OneClick. You can add device models to them. The items in these IP domains are synchronized with CA Performance Management, and their data is included in dashboards. Your CA Spectrum Global Collections become groups in the CA Performance Management Groups tree.
The integration extracts event data from the CA Performance Management Event Manager and converts it into CA Spectrum events. These events then raise CA Spectrum alarms on models in the SpectroSERVER topology. As clear events are processed, corresponding CA Spectrum alarms are cleared automatically. Polling for supported events begins when synchronization has completed. These events are converted into CA Spectrum alarm set or clear events and asserted on models in each landscape.
Alarms based on device performance, such as Time over Threshold and Deviation from Normal events, are generated in CA Spectrum to supplement fault and availability monitoring. The CA Spectrum alarms that originate in the Event Manager can be viewed in the OneClick Console. The following image shows the alarm details in the OneClick console:

Finally, the integration enables a Data Aggregator data source to discover CA Spectrum devices without requiring you to manually create discovery profiles. The system creates discovery profiles, which are scheduled by default but can also be run manually.
Solution Architecture
The following facts describe the architecture of the CA Spectrum - CA Performance Management integration:
CA Performance Management and OneClick Web Server should be in time sync. That is, time difference must not be there between these two machines, otherwise, it causes CA PM alarms missing in 
Spectrum
.
  • One SpectroSERVER or a Distributed SpectroSERVER (DSS) can be synchronized with CA Performance Management by specifying the OneClick web server as a CA Performance Management data source.
    • Full synchronization occurs when the data source is first added to CA Performance Management.
       If a full synchronization is required after you add the data source, we recommend running it during nonbusiness hours.
    • Incremental synchronization occurs every 5 minutes.
      Additions, removals, and modifications of devices, interfaces, and Global Collections in CA Spectrum are reflected in CA Performance Management after incremental synchronization.
  • Each landscape in the DSS is defined as a CA Performance Management group.
  • Devices and interfaces in the DSS are synchronized with CA Performance Management and added to the appropriate landscape group.
  • OneClick polls the Event Manager for events that are relevant to a specified landscape group. This polling happens every 60 seconds by default. Any retrieved events are then translated to CA Spectrum events, which can generate or clear alarms.
     CA Performance Management-related alarm processing in CA Spectrum applies to device and interface models that have been synchronized to CA Performance Management. Only events that are related to devices or interfaces that are modeled in CA Spectrum are processed by OneClick.
  • The Event Manager database is polled for supported events at each polling interval. With CA Performance Management v2.0.00 and later, you can modify supported events.

Upgrade Considerations
In previous versions of the CA Spectrum - CA Performance Management integration, all CA Spectrum models were contributed to the CA Performance Management Inventory. And these models were always associated with the Default IP Domain. From CA Spectrum Release 9.4 and CA Performance Management Release 2.3, you can precisely control the items that CA Spectrum contributes to CA Infrastructure Management, and you can control IP domain membership. The OneClick features for creating and maintaining Global Collections can now be applied to IP domains.
Be sure to account for the following key considerations when you are planning for the integration:
  • Only those models that you have added to a CA Performance Management IP Domain model in OneClick are synchronized with CA Performance Management.
  • The devices are added to CA Performance Management based on the specific CA Performance Management IP Domain with which the device models are associated in CA Spectrum.
  • If you are upgrading an existing integration, you must at minimum define the contents of the default CA Performance Management IP Domain model in CA Spectrum. You can add additional IP domains as required in the CA Performance Management Admin pages.
  • To move a device from the CA Performance Management Default IP Domain to another domain, you must first add the device to the desired IP Domain in CA Spectrum.
    If the device already exists in CA Performance Management, however, you must delete the device from the Default IP Domain. At the next synchronization, the device will be added to the updated IP domain in CA Performance Management.
Supported Features
Earlier versions of CA Spectrum integrate with both CA NetQoS Performance Center v6.1 and CA Performance Management v2.0.00 through r2.2.00. To integrate with CA Performance Management versions that predate r2.300, consult an earlier version of this section.
The following list identifies supported features in the integration between CA Spectrum starting from Release 9.4 and CA Performance Management Release 2.3.00.
 
Events
 
  • ThresholdViolation events: These events from Data Aggregator and CA Network Flow Analysis data sources are integrated and supported by default in CA Spectrum.
  • Other events: By updating an XML file and some event support files, you can instruct OneClick to handle events in the Event Manager database that were reported by other data sources.
 
IP Domains
 
  • CA Performance Management IP domains are synchronized as CA Performance Management IP Domain models in OneClick. Place device models into CA Performance Management IP Domains manually, or define collection rules to dynamically collect device models. The contents of the CA Performance Management IP domain model are used to keep the IP domain membership up to date in CA Performance Management. As new devices are sent to CA Performance Management from CA Spectrum, they are assigned to the IP domain that corresponds to their CA Performance Management IP Domain membership in CA Spectrum.
 
Groups
 
  • Your CA Spectrum Global Collections and landscapes are synchronized with CA Performance Management and displayed as groups in the CA Performance Management Groups tree. As part of the Groups tree, you can leverage the synchronized Global Collections in a variety of ways:
    • Create reporting groups
    • Define site membership
    • Drive the content of other custom groups and collections
  • CA Spectrum devices can be added to CA Performance Management Service Provider groups and shared among multiple tenant users.
 
Drilldown from OneClick to CA Performance Management Performance Data
 
  • You can access CA Performance Management performance data from CA Spectrum device and interface models. You gain rapid access to information about device performance issues in context.
 
Synchronized Discovery
 
  • Shared discovery eases administrative burden.
  • Place CA Infrastructure Management Data Collectors where you require them and leverage discovery data from multiple SpectroSERVERs. Determine the appropriate number of IP Domains that are required, and deploy a Data Collector for each IP Domain.
    At device inventory synchronization, Data Aggregator determines whether each device is new or is already in the inventory. When Data Aggregator encounters a device that it is not monitoring, it adds the IP address to a predefined Discovery profile. A discovery profile is defined for each IP Domain. The IP address for each device is added to the corresponding discovery profile based on its membership in a CA Performance Management IP Domain model within CA Spectrum. You can then run this Discovery profile manually, or you can let it run once a day through an automatically configured threshold.
 
Intelligent Interface Synchronization
 
  • Device monitoring by CA Spectrum always includes all associated interfaces. CA Performance Management retrieves information about all interfaces from CA Spectrum.
    However, the interface inventory in CA Performance Management does not include interfaces that have only been contributed by CA Spectrum. Instead, the inventory is filtered to include interfaces that are monitored by a performance monitoring data source, such as Data Aggregator or CA Network Flow Analysis.
 
Life cycle management
 
  • Using CA Spectrum you can control the life cycle state of devices in CA Performance Management. Changes in CA Spectrum trigger changes in CA Performance Management. For more information, see the Manage Device Life Cycles section in the CA Performance Management - 2.8 documentation.
