IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1
Durable Subscriptions workspace
In this workspace, you can view statistic counters for the durable subscriptions of a selected topic.
The default messaging provider supports the use of durable subscriptions to topics. This enables a subscriber to receive a copy of all messages published to a topic, even messages published during periods of time when the subscriber is not connected to the server. WAS 5.1 based products do not support this workspace. This workspace displays data provided by the Durable Subscriptions attributes.
- This workspace reports blanks for resource data on the first invocation if PMI data collection is configured for on-demand sampling (that is, if your site set configuration value Resource Data Collection Method to On Demand) or if you have not yet run applications that generate PMI resource data. To report resource data in this workspace after installing and configuring the data collector, use the WebSphere administrative console to set the appropriate PMI instrumentation level.
- Because of high overhead, the Tivoli Enterprise Monitoring Agent provides on demand sampling by default. To activate PMI monitoring, first select this workspace and then select it again later. Each time you select the workspace, it displays the data collected during the interval between selections.
The predefined workspace contains the following items:
- Durable Subscriptions report, which displays information about durable subscriptions that pertain to a selected topic, including the number of messages consumed, and message wait time
Access the Durable Subscriptions workspace
