# SECTION: Monitor Various Aspects of the Running Host<br />
#<br />
# The following check up on various aspects of a host. <br />
<br />
# disk: Check for disk space usage of a partition.<br />
# The agent can check the amount of available disk space, and make<br />
# sure it is above a set limit. <br />
# <br />
# disk PATH [MIN=100000]<br />
# <br />
# PATH: mount path to the disk in question.<br />
# MIN: Disks with space below this value will have the Mib's errorFlag set.<br />
# Can be a raw integer value (units of kB) or a percentage followed by the %<br />
# symbol. Default value = 100000.<br />
# <br />
# The results are reported in the dskTable section of the UCD-SNMP-MIB tree<br />
<br />
disk / 10000<br />
disk /var/local/storage 10000<br />
disk /var/local/backup 10000<br />
<br />
# load: Check for unreasonable load average values.<br />
# Watch the load average levels on the machine.<br />
# <br />
# load [1MAX=12.0] [5MAX=12.0] [15MAX=12.0]<br />
# <br />
# 1MAX: If the 1 minute load average is above this limit at query<br />
# time, the errorFlag will be set.<br />
# 5MAX: Similar, but for 5 min average.<br />
# 15MAX: Similar, but for 15 min average.<br />
# <br />
# The results are reported in the laTable section of the UCD-SNMP-MIB tree<br />

== Sensors ==<br />
lm_sensors package <br ><br />
The following is needed on IT8712 board to make "sensors" work:<br /><br />
/etc/default/grub<br />
<br />
GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"<br />
<br />
Also need to compile custom module for IT8728F<br />
1.Download kernel source<br />
$ apt-get source linux-image-2.6.38-8-generic<br />
<br />
2.Create test directory:<br />
$ mkdir ~/test<br />
$ cd ~/test<br />
<br />
3.Copy over it87.c <br />
$ cp /home/willh/linux-2.6.38/drivers/hwmon/it87.c ./<br />
<br />
4.Create Makefile<br />
obj-m += it87.o<br />
<br />
all:<br />
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules<br />
<br />
clean:<br />
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean<br />
<br />
5.To build kernel module enter:<br />
$ make<br />
<br />
6.(HACK)Copy new module to current kernel directory<br />
$ cd /lib/modules/2.6.38-8-generic/kernel/drivers/hwmon<br />
$ mv it87.ko it87.ko.orig<br />
$ cp ~/test/it87.ko ./<br />
<br />
7.Load the new module<br />
$ modprobe -v it87<br />
insmod /lib/modules/2.6.38-8-generic/kernel/drivers/hwmon/it87.ko <br />
<br />
8.Test it<br />
