Please see following description for synopsis


Erlang Application Definition                                        os_mon(7)

       os_mon - OS Monitoring Application

       The operating system monitor, OS_Mon, provides the following services:

         * cpu_sup CPU load and utilization supervision (Unix)

         * disksup Disk supervision(Unix, Windows)

         * memsup Memory supervision (Unix, Windows)

         * os_sup Interface to OS system messages (Solaris, Windows)

       To  simplify  usage  of OS_Mon on distributed Erlang systems, it is not
       considered an error trying to use a service at a node where it  is  not
       available (either because OS_Mon is not running, or because the service
       is not available for that OS, or because the service is  not  started).
       Instead, a warning message is issued via error_logger and a dummy value
       is returned, which one is specified in the man pages for the respective

       When  OS_Mon  is started, by default all services available for the OS,
       except os_sup, are automatically started.  This  configuration  can  be
       changed using the following application configuration parameters:

         start_cpu_sup = bool():
           Specifies if cpu_sup should be started. Defaults to true.

         start_disksup = bool():
           Specifies if disksup should be started. Defaults to true.

         start_memsup = bool():
           Specifies if memsup should be started. Defaults to true.

         start_os_sup = bool():
           Specifies if os_sup should be started. Defaults to false.

       Configuration  parameters  effecting  the different OS_Mon services are
       described in the respective man pages.

       See config(4) for information about how to change the value of configu-
       ration parameters.
