Optimizing queries
This section contains information about tuning the queries that are processed to display the tables, charts, and graphs that make up workspace views within the Tivoli Enterprise Portal.
Review these topics and considerations for relevancy to your environment.
- Processing queries
The query assigned to a chart or table view requests data from a particular attribute group. It executes when you open or refresh the workspace. Queries make up the processing load for on-demand data collection.
- Define custom queries
Custom queries reduce network traffic, processing at the agent and Tivoli Enterprise Monitoring Server, and memory usage at the Tivoli Enterprise Portal Server and Tivoli Enterprise Portal client. Custom queries accomplish this by limiting the number of rows and columns passed from the Tivoli Enterprise Monitoring Agent to the Tivoli Enterprise Monitoring Server.
