settings in the Warehouse configuration file.
Procedure
Diagnostic and corrective actions
1. To perform a diagnostic action, review the current CTIRA_NCSLISTEN and
KHD_QUEUE_LENGTH settings in the Warehouse configuration file.
2. To perform a corrective action, set CTIRA_NCSLISTEN equal to at least 20 times
the value of KHD_EXPORT_THREADS and increase KHD_QUEUE_LENGTH equal to a
value greater than the number of agents being handled by that Warehouse
Proxy agent .
Resolving warehouse proxy agent problems - connectivity
Warehouse Proxy agent problems, such as the inability to send data to the Tivoli
Data Warehouse, can be resolved by ensuring that agent can export data and that
it is not too busy.
About this task
To resolve warehouse proxy agent problems, you perform diagnostic and corrective
actions. These actions include verifying that the warehouse database password and
user ID are correct. Also, you can update the configuration parameters.
Procedure
Diagnostic and corrective actions
1. To perform diagnostic actions:
a. Verify component connectivity through the Self-Monitoring Topology
workspace. To open this workspace right-click the Enterprise Navigator
item, and then select Workspace > Self-Monitoring Topology.
b. Verify that the warehouse database password and user ID are correct and
have not expired.
c. Look at the Warehouse Proxy agent RAS1 logs for export resource
availability timeout. The Warehouse Proxy agent might be unable to export
because it is too busy.
2. To perform a corrective action:
v Update the configuration parameters. See “Environment variables” in the
IBM Tivoli Monitoring Installation and Setup Guide.
Resolving summarization and pruning agent problems
Summarization and pruning agent problems, such as unexpected values for
attributes can be resolved by reviewing the documentation for the monitoring
agents that are producing the unexpected values.
The causes of monitoring server problems include: Summarization and Pruning
agent yield unexpected values; unanticipated attribute behavior leads to
unexpected data.
About this task
To resolve summarization and pruning agent problems, you perform diagnostic
and corrective actions. These actions include comparing real-time data from a
workspace view with the unexpected data.
