CPU Utilization During Data Collection

Overview

The data collection task runs many threads in parallel to overlap computing and database operations with the wait for managed nodes to respond. On slower systems, this could potentially saturate the CPU for some time, depending on the processor speed of the CMS system and the number of systems being collected. Therefore, HP Systems Insight Manager provides some strategies to lessen the CPU usage.

Implementation

To lessen the CPU usage during data collection on the CMS:

Limit the number of systems that are being collected at one time. For example, create separate data collection tasks for different groups of systems and schedule them to run at different times.
Configure the CMS to use a remote database on a system other than the CMS. A substantial portion of the CPU load is consumed by the database during data collection. This option is only supported with a Windows CMS.
Lower the DataCollectionThreadCount parameter in the globalsettings.props file. This parameter defaults to 3. Lowering it to 2 or 1 reduces the CPU demand of data collection tasks, but it increases the time required to complete the tasks.
