When an issue occurs in the infrastructure, alert data is sent from CA UIM to the SpectroSERVER of CA Spectrum through the Southbound Gateway component. SpectroSERVER is a primary server for CA Spectrum. For more information, see the SpectroSERVER and CA Spectrum Databases section.
Using the Southbound Gateway, you can centralize network management, allowing CA Spectrum to capture and display data. Alert data is organized into CA Spectrum event and alarm data as appropriate and is displayed within OneClick.
The Southbound Gateway can be used with any incoming alert data stream format. The Southbound Gateway provides a simple, non-programmatic integration point for systems that can generate SNMP traps. It is also useful for managing non-SNMP environments. Southbound Gateway supplies an import tool that accepts XML-formatted alert data in case the system with which you are integrating cannot generate SNMP traps. For more information, see the section.
Once the Southbound Gateway receives the alert data, the data is mapped to a CA Spectrum event in an AlertMap file. The Southbound Gateway determines the appropriate EventAdmin model to receive the alert data based on the IP address of the host computer that is sending the data. The IP address of the host computer should match the IP address that is used to create the EventAdmin model.
The CA Spectrum EventAdmin model receives the trap and translates it into a CA Spectrum event. If the event corresponds to a critical, major, or minor condition, the corresponding alarm is raised on a CA Spectrum model. The model where the alarm is raised depends on a few factors. We recommend having a previously modeled device in CA Spectrum. If the device model is present in CA Spectrum, the alarm is asserted against the existing device model. If the device model does not exist in CA Spectrum the alarm is asserted against an auto-created EventModel of the Nimsoft Robot that is reporting the condition.
The following diagram illustrates the CA UIM - CA Spectrum Integration Architecture:
SPEC--Nimsoft Solution Architecture
  • CA UIM Probes
    Provide the intelligence to manage specific components on a managed device. For example, the cdm processes probe is responsible for monitoring CPU, disk, and memory usage on target hosts. Over 135 CA CA UIM probes are available, to let you manage the entire IT infrastructure, including servers, network devices, applications, and databases.
  • Nimsoft Alarm Server (NAS)
    Receives and manages incoming alarm messages. The Nimsoft Alarm Server supports message suppression and provides clients with services such as event updates, message filtering, automated actions, and mirroring capabilities.
  • Nimsoft SNMP Gateway Probe (snmpgtw)
    Sends out the traps from CA UIM to CA Spectrum. This probe converts alarms to SNMP-Trap messages which are readable by any SNMP-based management system. It subscribes to CA UIM internal alarms and processes these alarms into SNMP traps with all the information about the alarm that is encoded in the trap varbinds.
Coexistence and Compatibility with Previous Integrations
Multiple integrations between CA Spectrum and CA UIM have been developed in the past. You can install the current integration without uninstalling the previous integration because the present design uses distinct traps and developer IDs (event prefixes).
The current and previous integrations can therefore coexist. However, the two integrations do not share information with each other. The integrations remain as two separate integrations. We recommend activating only one integration with CA UIM at a time.
