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.
