IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Warehouse Proxy Agent
The Warehouse Proxy Agent provides a means of translating and transferring historical data collected by other monitoring agents to the Tivoli Data Warehouse.
The amount of historical data generated can be huge, particularly in environments with thousands of monitoring agents or when instance intense attribute groups are enabled.
This section describes Warehouse Proxy Agent configuration parameters that affect performance and throughput. For most environments, the default settings for these parameters provide good performance. If the Warehouse Proxy Agent starts to encounter errors when exporting data, these parameters may need adjustment. If the Warehouse Proxy Agent is not able to export data into the warehouse, or if it cannot keep up with the volume of export requests, export errors will be encountered at the storage location. The storage location can be the monitoring agent or the monitoring server, whichever is specified in the historical data collection configuration dialog.
Configuration parameters for the Warehouse Proxy Agent are set in the following files according to operating system:
- ITM_HOME\TMAITM6\khdenv
For example: C:\IBM\ITM\TMAITM6\khdenv
- ITM_HOME/config/hd.ini
For example: /opt/IBM/ITM/config/hd.ini
Be aware that whenever maintenance or reconfiguration takes place in your environment, these files might be recreated and configuration changes can be lost and require reapplication.
