os_mon(7)

NAME
os_mon - OS Monitoring Application

DESCRIPTION

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 services.

CONFIGURATION

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(5) for information about how to change the value of configuration parameters.
