Changes in
DX NetOps Spectrum
10.4.2
In the current release,
DX NetOps Spectrum
-DX Infrastructure Manager integration has the following changes:
Handling of Unreported Inventory
From 10.4.2,
DX NetOps Spectrum
identifies unreported inventory from DX Infrastructure Manager entities and deletes the unreported inventory if inventory does not exist in DX Infrastructure Manager. When the inventory exists in DX Infrastructure Manager after the sync, it retains the unreported inventory to verify after the next synchronization. By default, the attribute is enabled. If
deleteUnreportedEntities
attribute is enabled in
DX NetOps Spectrum
,
DX NetOps Spectrum
checks the presence of the unreported inventory models in DX Infrastructure Manager and deletes the models that are no longer present in DX Infrastructure Manager.
Follow these steps:
  1. Log in to the OneClick WebApp.
  2. On the
    Navigation
    tab, navigate to
    UIM Manager
    .
  3. In the
    Components Detail
    section, select
    Attribute
    tab.
  4. Search
    deleteUnreportedEntities
    to view the current setting, enabled by default.
  5. Right-click the
    deleteUnreportedEntities
    attribute and select
    Edit
    .
  6. In the
    Edit UIM Manager
    popup, change the setting if required.
  7. Select
    OK
    to apply the change.
    The
    Attribute Edit Results
    window shows the status.
  8. Close the window, on the successful assignment of the attribute.
Changes in
DX NetOps Spectrum
10.4.1
In the current release,
DX NetOps Spectrum
-UIM integration has the following changes:
Customize the HostSsync Payload Size in OneCLick
From 10.4.1, you can customize the maximum size of the payload that you want to receive from the spectrumgtw probe to
DX NetOps Spectrum
during the host server sync. Set the org.
apache.cxf.stax.maxInputSizeInMB
parameter to a desired value in the
Spectrum_HOME\tomcat\webapps\spectrum\WEB-INF\web.xml
file.
Default:
8 MB
Include Virtual Machines
When you select the
Include Virtual Machines
checkbox,
DX NetOps Spectrum
syncs only the non-VMWare VMs
From the spectrumgtw probe 8.68, the vmware probe-managed VMs are not synchronized as part of the host server sync.
Disable the Host Server Integration
When you disable the
Host Server Integration
, the sync stops and deletes the existing entities from
DX NetOps Spectrum
. You can change the retaining of the models in
DX NetOps Spectrum
by using the
RetainModelsAndRelations
attribute in the UIM Manager model.
The following are the supported integration modes and the resulting actions in
DX NetOps Spectrum
:
  • DELETE_MODELS: Delete models from
    DX NetOps Spectrum
    .
    Default value
  • DELETE_RELATIONS: Retain the models and delete the relationships of models.
  • RETAIN_ALL: Keep both relations and models in
    DX NetOps Spectrum

The architecture for the
DX NetOps Spectrum
and UIM integration has undergone major changes from 10.1.2. We recommend you to go through the
DX NetOps Spectrum
-UIM Integration using spectrumgtw probe - FACT SHEET
to understand the changes to the integration if you are new to this integration or an existing user.
Here are some key changes to the integration architecture:
  • Alarms sent from UIM to
    DX NetOps Spectrum
    will no longer leverage the SNMP Gateway or
    DX NetOps Spectrum
    Southbound gateway. Instead, they will be routed through the new
    DX NetOps Spectrum
    Gateway Probe.
  • Nisapi-service-host is replaced by nisapi-wasp for inventory sync from UIM to
    DX NetOps Spectrum
  • Server Management
    • Has removed dependency on dedicated role
    • Added ability to monitor VM as a server without dependency on Vmware probe
    • Pulls inventory with one of the roles in the database as DatabaseServer, Host, VirtualMachine, VirtualMachineHost, WebServer, vCenter.
  • Vmware Management
    • Handle Flapping inventory/relationships from UIM
    • Unreported inventory by UIM will be kept in a separate container in
      DX NetOps Spectrum
      and can be deleted by the user when no more needed
Here's an overview of the updated integration architecture:

Architectural Overview - using SBGW component /snmpgtw probes (till r10.1.1)
When an issue occurs in the infrastructure, alert data is sent from UIM to the SpectroSERVER of
DX NetOps Spectrum
through the Southbound Gateway component. SpectroSERVER is a primary server for
DX NetOps Spectrum
. For more information, see the SpectroSERVER and
DX NetOps Spectrum
Databases
section.
Using the Southbound Gateway, you can centralize network management, allowing
DX NetOps Spectrum
to capture and display data. Alert data is organized into
DX NetOps 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
DX NetOps 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
DX NetOps Spectrum
EventAdmin model receives the trap and translates it into a
DX NetOps Spectrum
event. If the event corresponds to a critical, major, or minor condition, the corresponding alarm is raised on a
DX NetOps Spectrum
model. The model where the alarm is raised depends on a few factors. We recommend having a previously modeled device in
DX NetOps Spectrum
. If the device model is present in
DX NetOps Spectrum
, the alarm is asserted against the existing device model. If the device model does not exist in
DX NetOps Spectrum
the alarm is asserted against an auto-created EventModel of the Nimsoft Robot that is reporting the condition.
The following diagram illustrates an overview of the UIM -
DX NetOps Spectrum
Integration Architecture, till 10.1.1:
SPEC--Nimsoft Solution Architecture
The integration between
DX NetOps Spectrum
and UIM through Web Server is designed to support server management. The HostServer models resulting from the integration provides traditional
DX NetOps Spectrum
capabilities such as layer2 connectivity and fault isolation with the features supported by UIM. You can use the Launch-in-Context feature to launch the CA Unified Management Portal (UMP) view from the server models in
DX NetOps Spectrum
to view the server information.
When the UIM and
DX NetOps Spectrum
integration is enabled from the OneClick Administration page,
DX NetOps Spectrum
receives the data from UIM through the Rest API. Once we get the data from the Rest API, UIM hosts are modeled in
DX NetOps Spectrum
. The alert data is sent from UIM to the SpectroSERVER of
DX NetOps Spectrum
through the Southbound Gateway component. The received data is mapped to a
DX NetOps Spectrum
event. The Southbound Gateway determines the appropriate EventAdmin model to forward the event. Metric violation traps that are coming from UIM are asserted on the respective Nimsoft host models in
DX NetOps Spectrum
.
The following diagram illustrates the architecture of the UIM -
DX NetOps Spectrum
Integration for Server Management through the Web Server (till v10.1.1):
Server management_WebServer.png
  • 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 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.
  • SNMP Gateway Probe (snmpgtw)
    Sends out the traps from UIM to
    DX NetOps Spectrum
    . This probe converts alarms to SNMP-Trap messages which are readable by any SNMP-based management system. It subscribes to UIM internal alarms and processes these alarms into SNMP traps with all the information about the alarm that is encoded in the trap varbinds.
