Configuring the IBM Tivoli Usage and Accounting Manager agent

You can configure and start the IBM® Tivoli® Usage and Accounting Manager agent on the Virtual I/O Server.

With Virtual I/O Server 1.4, you can configure the IBM Tivoli Usage and Accounting Manager agent on the Virtual I/O Server. Tivoli Usage and Accounting Manager helps you track, allocate, and invoice your IT costs by collecting, analyzing, and reporting on the actual resources used by entities such as cost centers, departments, and users. Tivoli Usage and Accounting Manager can gather data from multi-tiered datacenters that include Windows®, AIX®, Virtual I/O Server, HP/UX Sun Solaris, Linux®, IBM i, and VMware.

Before you start, ensure that the Virtual I/O Server is installed. The Tivoli Usage and Accounting Manager agent is packaged with the Virtual I/O Server and is installed when the Virtual I/O Server is installed. For instructions, see Installing the Virtual I/O Server and client logical partitions.

To configure and start the Tivoli Usage and Accounting Manager agent, complete the following steps:

Optional: Add optional variables to the A_config.par file to enhance data collection. The A_config.par file is located at /home/padmin/tivoli/ituam/A_config.par. For more information about additional data collectors available for the ITUAM agent on the Virtual I/O Server, see the IBM Tivoli Usage and Accounting Manager Information Center.
List all of the available Tivoli Usage and Accounting Manager agents using the lssvc command. For example,
```
$lssvc
ITUAM_base
```
Based on the output of the lssvc command, decide which Tivoli Usage and Accounting Manager agent you want to configure. For example, ITUAM_base
List all of the attributes that are associated with the Tivoli Usage and Accounting Manager agent using the cfgsvc command. For example:
```
$cfgsvc –ls ITUAM_base
 ACCT_DATA0
ACCT_DATA1
ISYSTEM
IPROCESS
```
Configure the Tivoli Usage and Accounting Manager agent with its associated attributes using the cfgsvc command:
```
cfgsvc ITUAM_agent_name -attr ACCT_DATA0=value1 ACCT_DATA1=value2 ISYSTEM=value3 IPROCESS=value4
```
Where:
- ITUAM_agent_name is the name of the Tivoli Usage and Accounting Manager agent. For example, ITUAM_base.
- value1 is the size (in MB) of the first data file that holds daily accounting information.
- value2 is the size (in MB) of the second data file that holds daily accounting information.
- value3 is the time (in minutes) when the agent generates system interval records.
- value4 is the time (in minutes) when the system generates aggregate process records.
Start the Tivoli Usage and Accounting Manager agent using the startsvc command. For example:
```
startsvc ITUAM_base
```

After you start the Tivoli Usage and Accounting Manager agent, it begins to collect data and generate log files. You can configure the Tivoli Usage and Accounting Manager server to retrieve the log files, which are then processed by the Tivoli Usage and Accounting Manager Processing Engine. You can work with the data from the Tivoli Usage and Accounting Manager Processing Engine as follows:

You can generate customized reports, spreadsheets, and graphs. Tivoli Usage and Accounting Manager provides full data access and reporting capabilities by integrating Microsoft® SQL Server Reporting Services or Crystal Reports with a Database Management System (DBMS).
You can view high-level and detailed cost and usage information.
You can allocate, distribute, or charge IT costs to users, cost centers, and organizations in a manner that is fair, understandable, and reproducible.
