To make historical data available for reporting in workspace
views, you must configure and start historical data collection for
the appropriate products and attribute groups. This is done through
the History Collection Configuration window.
Understanding historical configuration
It is necessary to configure historical data collection
for attribute groups and distribute to managed systems before users
can see historical data in the Tivoli Enterprise Portal. Read this
topic to understand the configuration settings and their implications.
Creating a historical collection
A historical data collection specifies the attribute group
to collect data from, where to store the historical data, and other
information such as the collection frequency and distribution. Create
a historical collection definition for every attribute group that
you want to collect historical data for. You can then retrieve the
historical data into query-based views.
Distributing a historical collection
Distribute a historical collection definition to the managed
systems that you want to save data samples from. Data collection begins
as soon as you save the distribution. Edit the distribution list whenever
you want to start or stop historical sampling on certain managed systems
or managed system groups.
Creating another historical collection
After historical collection definitions have been created,
use the History Collection Configuration window to create duplicates
that you can customize for different collection intervals, warehousing
intervals, and distribution.
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.
Starting data collection
You can start collection of historical data for attribute
groups on selected managed systems and whenever you have managed systems
that you want to add.
Changing the distribution method
Change the distribution method from Managing
System (TEMS) to Managed System (Agent) to
enable the historical collection definition to be added to a historical
object group.
Removing a historical data collection
Use the History Collection Configuration window to remove
any unnecessary historical data collection definitions.
