Using multiple Transaction Reporters

For ITCAM for Transactions V7.2.0.2 and later, you can use multiple Transaction Reporters to collect data from a single Aggregation agent if required. This scenario should not be necessary except in very large enterprise environments.

Specifying the shared Aggregation agent

For each Transaction Reporter, include the name of the shared Aggregation agent in the Aggregation agent List. This list is a Transaction Reporter data collection setting. Reconfigure the Transaction Reporter using the Manage Tivoli Enterprise Monitoring Services. See Transaction Reporter agent configuration parameters for further information.

Considerations when using multiple Transaction Reporters

To minimize any problems that you may have using multiple Transaction Reporters follow these guidelines:

Start the Transaction Reporters at the same time.
Because baselines and deviations are calculated independently at each Transaction Reporter, if you start the Transaction Reporters at the same time, you reduce the likelihood of data from the same Transaction Collector being displayed in different periods in the separate Transaction Reporters. The baseline and deviation metrics are dependent on how long each Transaction Reporter has been collecting data from the Transaction Collector. This data may vary slightly between the Transaction Reporters based on the difference in how long each Transaction Reporter has been running.
Define only one Transaction Reporter in a situation for a specific application.
