IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Configure summarization and pruning for attribute groups
Configure summarization and pruning for the Tivoli Data Warehouse to aggregate data and keep the database size at a manageable level.
The summarization and pruning agent must be installed, configured, and started as described in the IBM Tivoli Monitoring Installation and Setup Guide.
Your user ID must have Configure History permission to open the History Collection Configuration window. If you do not have this permission, you will not see the menu item or tool for historical configuration.
Although summarization and pruning is not mandatory for warehoused data, it keeps the database from growing to an unwieldy size and minimizes the amount of data that gets retrieved to the Tivoli Enterprise Portal. Even if data collection for an attribute group has not been configured, you can set up summarization and pruning. If no collections have been created and distributed for an attribute group, no data goes to the warehouse, and summarization and pruning does not take place.
Procedure
- If the History Collection Configuration window is not open, click History Configuration.
- Select a Monitored Application from the tree.
- Review the attribute groups in the table. If summarization and pruning has already been configured for an attribute group, the values will be shown in the summarization and pruning cells. Collapse the tree, drag the borders, or scroll the table right to see all the cells.
- Select one or more attribute groups to configure. You can select multiple groups with Ctrl+click, or Shift+click to select all groups from the first one selected to this point. The settings of the first group selected continue to display, regardless of the settings in any of the other selected groups. This enables you to adjust the configuration controls once and apply the same settings to all selected attribute groups. Use the Clear all button if you want to clear all the fields and start over.
- In the Summarization area, select the check box for every time period to be aggregated: Yearly, Quarterly, Monthly, Weekly, Daily, and Hourly.
- In the Pruning area, select the check box for every time period to be pruned: Yearly, Quarterly, Monthly, Weekly, Daily, and Hourly. If you also want to keep the original data samples, select the Detailed data check box. In the corresponding fields, specify the number of days, months, or years to keep the data.
- Click Apply to save the configuration for the attribute groups that were selected. The summarization and pruning cells for the attribute group are updated to reflect the new settings.
What to do next
The next time summarization and pruning takes place, the summarization and pruning agent applies the configuration to the long-term data stored in the data warehouse. Wait for the next scheduled time period to elapse before expecting to see any summarized data.To configure granular summarization and pruning for managed system groups, use the tacmd Command Line Interface (CLI). For detailed instructions, see the IBM Tivoli Monitoring Administrator's Guide.
