# SECTION: Monitor Various Aspects of the Running Host
#
#   The following check up on various aspects of a host. 

# disk: Check for disk space usage of a partition.
#   The agent can check the amount of available disk space, and make
#   sure it is above a set limit.  
#   
#    disk PATH [MIN=100000]
#   
#    PATH:  mount path to the disk in question.
#    MIN:   Disks with space below this value will have the Mib's errorFlag set.
#           Can be a raw integer value (units of kB) or a percentage followed by the %
#           symbol.  Default value = 100000.
#   
#   The results are reported in the dskTable section of the UCD-SNMP-MIB tree

disk  / 10000
disk  /var/local/storage 10000
disk /var/local/backup 10000

# load: Check for unreasonable load average values.
#   Watch the load average levels on the machine.
#   
#    load [1MAX=12.0] [5MAX=12.0] [15MAX=12.0]
#   
#    1MAX:   If the 1 minute load average is above this limit at query
#            time, the errorFlag will be set.
#    5MAX:   Similar, but for 5 min average.
#    15MAX:  Similar, but for 15 min average.
#   
#   The results are reported in the laTable section of the UCD-SNMP-MIB tree

Sensors

lm_sensors package
The following is needed on IT8712 board to make "sensors" work:

/etc/default/grub

GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"

Also need to compile custom module for IT8728F 1.Download kernel source

$ apt-get source linux-image-2.6.38-8-generic

2.Create test directory:

$ mkdir ~/test
$ cd ~/test

3.Copy over it87.c

$ cp /home/willh/linux-2.6.38/drivers/hwmon/it87.c ./

4.Create Makefile

obj-m += it87.o
 
all:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

5.To build kernel module enter:

$ make

6.(HACK)Copy new module to current kernel directory

$ cd /lib/modules/2.6.38-8-generic/kernel/drivers/hwmon
$ mv it87.ko it87.ko.orig
$ cp ~/test/it87.ko ./

7.Load the new module

$ modprobe -v it87
 insmod /lib/modules/2.6.38-8-generic/kernel/drivers/hwmon/it87.ko 

8.Test it
