Connection Properties - Overhead Page
The queries that Spotlight uses to collect data from a Spotlight connection can place an additional load on the monitored system.
- Simple queries that retrieve small amounts of data have little impact on the performance of the monitored system.
- Most Spotlight queries consume a measurable but not significant amount of system resources.
- Queries that are complex or collect large amounts of data may put a significant load on the system.
The controls on the Overhead Management page allow you to adjust collection rates for different categories of Spotlight data, and so limit the load that Spotlight places on the monitored system.
