Change CEI distribution mode settings

Use this page to view and change the Common Event Infrastructure (CEI) configuration properties for a specific model version. These values are applicable only for the selected version of the monitor model.

To view this administrative console page, click Applications > Monitor Models > version_id > Change CEI distribution mode.

General properties

Use these properties to configure a specific version of a monitor model.

Distribution Mode

Identifies the current and target configuration of the monitor model selected.
Current
Displays how the version is currently configured to receive and process Common Base Events.
Target
Specifies how the version is configured to receive and process Common Base Events. When appropriate, a list is enabled for you to select a new configuration mode.
The CEI distribution mode is a combination of the state of the monitor model and the transport type.
  • The possible states of a monitor model are:
    • Active
    • Active (no new MC instances)
    • Inactive (event queue recoverable)
    • Inactive
  • The transport types are:
    • Queue-based event delivery. This method uses Java Messaging Service (JMS) to deliver events from CEI to the monitor model.
    • Table-based event delivery (formerly known as queue bypass). This method uses a database table to deliver events from CEI to the monitor model. With table-based event delivery, the work can be distributed among multiple cluster members. For most environments, this method improves performance and simplifies the system configuration.
    Note: The Inactive distribution mode is the same for both transport types.
The combination of the monitor model state and transport type results in the following possible distribution modes:
Table 1. Distribution modes
State Definition Queue-based Table-based
Active Events are processed and new monitoring context instances can be created as a result. Active (Queue-based event delivery) Active (Table-based event delivery)
Active (no new MC instances) Events for existing monitoring context instances are processed, but events that would create new root monitoring context instances are ignored. Active (Queue-based event delivery, no new MC instances) Active (Table-based event delivery, no new MC instances)
Inactive (event queue recoverable) Events are saved for a future monitor model version to process. The events are not processed by the current monitor model version. Inactive (Queue-based event delivery, event queue recoverable) Inactive (Table-based event delivery, event queue recoverable)
Inactive Events are not distributed to this monitor model version. Inactive Inactive
