Announcement Support for this product will end on November 3, 2025. We recommend that you use PATROL for Linux, PATROL for AIX, or PATROL for Solaris to monitor operating systems.

-Ctrl and -Coll Parameters

The DCM data collection method gathers data using both the Perform Agent and the BMC PATROL PSL collectors. Ultimately, consumer parameters display the information gathered by both types of collection. However, understanding how each type of collector gathers data and which type of collector feeds a consumer helps understand apparent discrepancies in system statistics. These discrepancies can be due to poorly managed discovery cycles or other performance-tuning issues.

-Ctrl Suffix

Parameters with -Ctrl suffix are standard parameters that interact with the Perform Agent through the DCM application. These parameters control the poll time and status (active or inactive) for data collection of application parameter data.

Warning

Note

When using the BMC PATROL KM for Event Management to schedule the polling cycle for various <appClass > Ctrl parameters, you must use the variable __ANYINST__ rules. The minimum polling cycle is 10 seconds. Because of potential performance issues, take care when decreasing the polling cycle or increasing the amount of history data.

-Coll Suffix

Parameters with the -Coll suffix are collector parameters that interact directly with UNIX utilities. This type of parameter issues the system calls and receives the data without having to interact with another data-gathering application.
