The conf/slm directory contains configuration files for service level monitoring (SLM) classes. The name of a file is the name of the SLM class it defines. SLM classes can be configured under the Catalogs > SLM section of the Admin Server UI or by using functions under the Catalog.SLM section of the SOAP API and CLI.
