IBM Tivoli Monitoring, Version 6.3

Stopping data collection

Stop data collection on one or more managed systems for a historical collection definition when you are no longer interested in gathering data on the managed system or would like to temporarily disable data collection.

Before you begin

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 tool for historical configuration.

About this task

The historical collections for an attribute group can be edited to stop data collection on some or all of the managed systems in the distribution list. The managed systems that remain in the distribution continue to collect historical data. Take these steps to stop data collection on a managed system or managed system group:

Procedure

  1. Click History Configuration to open the History Collection Configuration window.
  2. Click the monitored application (agent type).
  3. Click the collection that the managed system is assigned to.
  4. For managed systems that are assigned to the historical collection:
    1. Click the Distribution tab to see the managed systems, managed system groups, and historical object groups that collection is occurring on.
    2. In the Start collection on list, click the managed systems or managed systems groups (or both) that you want to stop collection on and move them back to the Available list. You can also use Ctrl+click to select multiple items and Shift+click to select all items between the item last selected and this one.
    3. If this is a historical object group, the name is disabled as are any managed systems and managed system groups that are assigned to the distribution through the historical group. Right-click a name and click Show Groups to see the historical configuration group it was distributed to, then complete the next step.
  5. For managed systems that are assigned to a historical configuration group:
    1. Click Group.
    2. Click the historical group in the Historical configurations branch.
    3. Click the Distributions tab.
    4. In the Assigned managed systems list, click the systems or groups (or both) that you want to stop collection on andmove them back to the Available list.
  6. To save your changes, click Apply to keep the window open or OK to close it.

Results

Historical data collection no longer occurs on the managed systems that you moved out of the Start collection on list for the historical collection definition or that you moved out of the Assigned managed systems list for the historical configuration group.

If data collection was stopped on all managed systems that were assigned to the historical collection, its icon changes to indicate that it is not distributed. Likewise, if data collection was stopped on all managed systems for an attribute group, the icon that indicates data collection is started in the summarization and pruning table no longer displays.

What to do next

If you want to verify that you removed a managed system or managed system group from all historical collection definitions, you can use the tacmd histlistcollections command to list all the collections that are started for a managed system or managed system group.

For example, histListCollections -m Primary:BRAZIL:NT shows all historical collections that are started on the managed system called Primary:BRAZIL:NT. See the IBM Tivoli Monitoring Command Reference for more information.

If your intention is to stop data collection on all managed systems for this collection permanently, delete the historical collection definition; if your intention is to stop data collection for the entire attribute group, delete all the collection definitions that were created for it.
