Use Centralized Configuration to update local configuration files on many monitoring agents.
You can use Centralized Configuration to host the Log File agent configuration and format files on a central http server. A user-provided XML file installed with the Tivoli Log File Agent describes where the http server is located, the paths to the files, and authentication information (if any). The agent then polls the server periodically, and downloads the files any time there are changes. The agent automatically notices that the local copies of the files changed, and reinitializes itself to use them.
For full setup details, see Centralized Configuration in the IBM® Tivoli® Monitoring Administrator's Guide.
