The PATROL for IT Data Analytics has the following types of parameters:
A PATROL collector parameter executes commands and gathers data for a consumer parameter to display, often collecting many values. It does not display any values itself. As such, it does not have alarms or run any recovery actions.
Collector parameters are defined in the collector's application class rather than in the applications for which they collect data. This avoids the situation in which a separate collector would execute for each application instance and negate the efficiency of the collector or consumer parameter.
A consumer parameter only displays a value that is collected by a collector parameter. A consumer parameter never issues commands; it is not scheduled for execution, but it has alarms and can run recovery actions. A consumer parameter cannot be updated directly by selecting an option on its display. To update a consumer parameter, you must execute the collector that gathers its data.
For additional information about parameters and defining your own parameters, see the PATROL Console Help or the PATROL user guide for your console.
Standard parameters issue commands to collect data and display the data collected. They contain alarm definitions and can run alarm and warning actions.
