Wild card matching is not supported. The only way to mimic that functionality
would be to use the substring or scan for string functions instead of the default
value and equals. The equals operator only works with full matches.
Too much historical data is collected
The Summarization and Pruning agent is responsible for generating and storing
summarized data, and pruning the data based on information that is stored in the
Tivoli Data Warehouse. The data in the data warehouse is a historical record of
activity and conditions in your enterprise. The size of summarization data that is
collected depends on the following criteria:
v
The number of agents collecting data
v
The number of table collected per agent
v
The size of the table (number and size of columns)
v
The collection interval (for example 5, 10, 15 or minutes)
Pruning data is deleting old data automatically, rather than manually. To reduce
the data that is collected, limit the size of your database tables by regularly
pruning old data from the data warehouse. If you installed the Summarization and
Pruning agent, your configuration settings are set to default values. You can view
the current values in the History Collection Configuration window. Refer to
"Changing configuration settings using the History Collection Configuration
window in the Tivoli Enterprise Portal" in the
IBM Tivoli Monitoring Administrator's
Guide
for instructions.
If you need to install the Summarization and Pruning agent, see the
IBM Tivoli
Monitoring Installation and Setup Guide
. There you can find information for
environment-wide capacity planning. You can find agent-specific capacity planning
information in the user guide for the specific monitoring agent.
Warehouse Proxy agent failed to export data
The ODBC connection enables the Warehouse Proxy agent to export data to the
warehouse database. The WAREHOUSELOG table lets you know how many
exports succeeded and how many failed because of an ODBC error or a TIMEOUT
issue. See the
IBM Tivoli Monitoring Installation and Setup Guide
for more
information about the WAREHOUSELOG table and configuring the Warehouse
Proxy agent.
