When a KM is disabled (added to the disabled list) in the agent configuration file, the KM files are not deleted from the PATROL Agent computers. However, the PATROL Agent stops using the KM to collect parameter data and run recovery actions. By default, no KMs are disabled. Most KMs are composed of individual application files with a .km extension. See also preloaded KM, static KM, and unload a KM.
