Deployment considerations for on premises Operations Management

The desired volume of events determines whether a basic, failover, or desktop architecture or a multitier architecture is deployed. The Gateway for Message Bus can be configured to support event inserts only or both inserts and reinserts.

The following explains the architecture and event volume, and the event analysis capacity of Operations Analytics - Log Analysis in more detail.

Note: Operations Analytics - Log Analysis Standard Edition is included in Netcool® Operations Insight®. For more information about Operations Analytics - Log Analysis editions, search for "Editions" at the Operations Analytics - Log Analysis documentation, at https://www.ibm.com/docs/en/SSPFMY.

Event volume

Event inserts are the first occurrence of each event and reinserts are every occurrence of each event. By default, the Gateway for Message Bus is configured to accept only event inserts from ObjectServers through an IDUC channel. To support event inserts and reinserts, you can configure event forwarding through the Accelerated Event Notification (AEN) client.

Note: Event Search functionality varies as follows depending on the choice of channel:

• IDUC channel: Event Search functionality is limited. Chart display functionality is fully available, but you will not be able to perform a deep dive into events or search for event modifications.
• AEN channel: All Event Search functionality is available. However, as part of your Netcool/OMNIbus configuration you will also have to install triggers in the ObjectServer.

For more information, search for Integrating with Operations Analytics - Log Analysis in the Gateway for Message Bus documentation.

Architecture of Netcool/OMNIbus

Basic, failover, and desktop architectures support low and medium capacity for analyzing events. Multitiered architectures support higher Operations Analytics - Log Analysis capacities. In a multitier architecture, the connection to the Gateway for Message Bus supports higher capacity at the collection layer than at the aggregation layer.

For more information about these architectures, see the Netcool/OMNIbus documentation and also the Netcool/OMNIbus Best Practices Guide.

Capacity of Operations Analytics - Log Analysis

The volume of events that Operations Analytics - Log Analysis is able to handle. For the hardware levels that are required for expected event volumes, see the Operations Analytics - Log Analysis documentation at https://www.ibm.com/docs/en/SSPFMY/welcome. If capacity is limited, you can use the deletion tool to remove old data.

Connection layer

The connection layer is the layer of the multitier architecture to which the Gateway for Message Bus is connected. This consideration applies only when the Netcool/OMNIbus product is deployed in a multitier architecture. The connection layer depends on the capacity of Operations Analytics - Log Analysis. For more information about multitier architectures, see the Netcool/OMNIbus documentation and also the Netcool/OMNIbus Best Practices Guide.
