Resolving warehouse proxy connection problems Tivoli Data Warehouse proxy agent connection problems can be resolved by verifying that the correct socket connection is being used. The causes of Warehouse Proxy agent problems might be because the short-term historical data is being stored at the monitoring agent or the Tivoli Enterprise Monitoring Server and should be switched, or because the Warehouse Proxy agent cannot connect to the data warehouse or to the monitoring server. About this task To resolve warehouse proxy connection problems, you perform diagnostic and corrective actions. These actions include verifying that the monitoring agent is connected to the Tivoli Data Warehouse and that the connection from the agent to the Tivoli Enterprise Monitoring Server is not being prevented by a firewall. Procedure Diagnostic and corrective actions 1. Ensure that the Warehouse Proxy agent is running. 2. Look for export failures to the Warehouse Proxy agent in either the monitoring agent RAS1 log or the monitoring server RAS1 log. Depending on where the error is found, see the monitoring agent steps or monitoring server steps below. v Monitoring agent: a. Verify that the correct socket connection is being used. b. Verify that the monitoring agent is connected to the Tivoli Data Warehouse. v Monitoring server: a. Verify that the connection between the monitoring server and Warehouse Proxy agent is not being stopped by a firewall. b. Verify that the correct port is being used for each component. 3. For corrective actions, perform the following steps: v Monitoring agent: - Store the collected data at the location of the monitoring server to ensure a stable connection. v Monitoring server: - Consider using a high port number for connecting to the monitoring server. See the "Controlling port number assignments" topics in the IBM Tivoli Monitoring Installation and Setup Guide for more information on the COUNT and SKIP options for port number allocation. Resolving warehouse proxy agent problems - configuration If the Warehouse Proxy agent is connected to the Tivoli Data Warehouse and Tivoli Enterprise Monitoring Server but cannot transmit data, change the environment variable settings in the Warehouse configuration file.
