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