The process by which Foglight for Oracle determines the maximum and minimum values for every dataflow on the home page, by observing data moving through the database system. This information helps Foglight for Oracle display the data flows correctly.
Cartridges extend the functionality of Foglight and are installed on the Foglight Management Server. A cartridge contains one or more components, such as agents for deployment, communication capabilities, and modifications to the way that data is transformed or handled, as well as rules, reports, and views. When a cartridge is installed and enabled, its components become part of the Management Server. Adding cartridges allows users to monitor additional parts of their environment. For further details about managing cartridges, See the Foglight Administration and Configuration Guide.
When SQL statements and other types of calls are made to Oracle, processing the calls requires spending a certain amount of CPU time. Whereas processing average calls requires a small amount of CPU time, a SQL statement involving a large amount of data or a runaway query can consume a much larger amount, thereby reducing the CPU time available for other processing.
CPU utilization is a key operating system statistic in the tuning process. Excessive CPU usage can result from an inadequately-sized system, untuned SQL statements, or inefficient application programs.
