IBM Tivoli Composite Application Manager for Applications, Version 7.2.1.1

Historical data tables

The amount of default space required for a 24-hour period on a monitored system varies greatly depending on customer configuration. The following estimates are taken from an example Windows system with the following WebSphere® Message Broker components installed: configuration manager, user name server, Message Brokers Toolkit, and a single message broker. The broker has two monitored execution groups, four message flows being monitored configured with two subflows, 12 CandleMonitor nodes, a total of 50 nodes with 150 terminals, and two threads per message flow. Accounting statistics has been turned on to collect all possible archive data for the four message flows with the default interval in place at 60 minutes, and the default agent parameter setting is in place to only collect archive data for history, not snapshot data.

Important: The historical collection interval must be set to the same value for each of the five statistics tables (broker statistics, execution group statistics, message flow statistics, subflow statistics, and CandleMonitor node statistics). Also, the historical collection interval must be set to the same value for each of the four accounting tables (message flow accounting, thread accounting, node accounting, and terminal accounting). The historical collection interval can be set to be a different value for the two groups of tables (statistics and accounting). The default for all collection is 15 minutes. Do not set up multiple collection intervals for either the statistics group of tables or the accounting group of tables because different settings of historical collection interval lengths can cause the data recorded historically to be inaccurate for these attribute groups.
