os_mon(7) Erlang Application Definition 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, VxWorks)
* 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 configu-
ration parameters.
