IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Summarized and pruned data availability
The first time the summarization and pruning tool is run, you might not get the results you expect. Review the installation and configuration tasks that must take place before you can expect to the data from the Tivoli Data Warehouse summarized and pruned.
The summarization and pruning procedure is dependent on having enough data in the data warehouse to work with, how the data collection and warehousing intervals are set, and whether the summarization and pruning specifications were set in the History Collection Configuration window. These installation and configuration tasks must be completed before summarized and pruned data is available from the warehouse:
- Install the monitoring agent, then add application support for it on the Tivoli Enterprise Monitoring Server and the Tivoli Enterprise Portal Server.
- Configure historical data collection for one or more attribute groups for the agent.
- Distribute the historical collection to managed systems to start collecting data.
- For each attribute group that has historical data collection taking place, configure the summarization and pruning intervals.
- Wait for at least one warehouse interval. Check to make sure data is in the warehouse in the detailed tables. It is not sufficient to query historical data from the Tivoli Enterprise Portal because the first 24 hours comes from the short-term history files and not the data warehouse.
- Configure the summarization and pruning agent, making sure that the test connection to the database works and that you schedule when the agent should perform work. You can configure the agent earlier, but wait for the scheduled run to complete before expecting the warehoused data to be summarized and pruned.
After the scheduled run time, you should have summary data in the warehouse.
