Certification Guide Series: IBM Tivoli Monitoring V 6.1

Chapter 7. Administration 177

The IBM Tivoli Monitoring V6.1 historical data collection architecture consists of

three primary components. The following components are used to collect data in

the IBM Tivoli Monitoring V6.1 architecture:

 Warehouse Proxy Agent

 Warehouse Summarization and Pruning Agent

 Tivoli Data Warehouse V2.1

The Warehouse Proxy Agent

The Warehouse Proxy Agent is the bridge between the active monitoring system

and the historical data repository. It handles warehousing requests from all

managed systems in the enterprise. It uses ODBC to write the historical data to a

supported relational database. Only one warehouse proxy agent can be

configured and running in an IBM Tivoli Monitoring instance (hub Tivoli

Enterprise Monitoring Server) at one time. The Warehouse Proxy can only

successfully connect to a hub monitoring server.

Summarization and Pruning Agent

The Summarization and Pruning Agent maintains the data within the data

warehouse by aggregation and pruning data based on customer

specifications.The IBM Tivoli Monitoring administrator sets up how often to

collect the detailed data, what intervals on which to aggregate and prune, and

how often to run the aggregation and pruning engine. Typically, the

summarization and pruning process is scheduled to run once a day.

Tivoli Data Warehouse V2.1

The Tivoli Data Warehouse database is an integral part of the solution. It stores a

large amount of attribute data, and customers will want to host this data on

existing database farms. The database is used by Tivoli Enterprise Portal if

historical data is represented. External reporting tools and other applications can

access the data and operate off of this database.

7.4.1 Historical data types

As mentioned, there are two types of data stores for the IBM Tivoli Monitoring

V6.1 historical data component.

 Short-term data

 Long-term data

Short-term data

Short-term data is typically referred to in IBM Tivoli Monitoring V6.1 as data that

is stored in binary files less than 24 hours. In the IBM Tivoli Monitoring V6.1

architecture, short-term data can be configured to store the binary files locally on
