=head1 NAME
|
||||
|
||||
smart_raw__ - Munin plugin to retreive raw SMART values from a disk.
|
||||
|
||||
=head1 APPLICABLE SYSTEMS
|
||||
|
||||
All machines with a SMART capable disk and smartmontools installed.
|
||||
|
||||
This plugin is very useful if you want to need to monitor a single raw S.M.A.R.T.
|
||||
value reported by a disk. Load Cycle Counts or Pending Sectors come to mind as
|
||||
these are a good indicator of problems with a disk.
|
||||
|
||||
=head1 CONFIGURATION
|
||||
|
||||
The plugin should be installed as smart_raw_sda_193 which means that the smart value
|
||||
numbered 193 will be read from the disk sda.
|
||||
|
||||
|
||||
Basic configuration for every system is that the plugin needs to be called as root
|
||||
in order to execute smartmontools.
|
||||
|
||||
Add the following to your /etc/munin/plugin-conf.d/smart_raw:
|
||||
|
||||
[smart_raw_sda_193]
|
||||
user root
|
||||
|
||||
=head1 INTERPRETATION
|
||||
|
||||
Smart RAW values are provided as is. You need to undertand what you are monitoring...

snmp__areca_ - Munin plugin to get temperature, voltage or fan speed values
|
||||
from Areca network enabled RAID controllers via SNMP.
|
||||
|
||||
=head1 APPLICABLE SYSTEMS
|
||||
|
||||
All machines with a SNMP capable ARECA raid controller.
|
||||
|
||||
=head1 CONFIGURATION
|
||||
|
||||
Make sure your Areca controller is accessible via SNMP from the munin host:
|
||||
snmpwalk -v 1 -c snmp_community ip.add.re.ss
|
||||
|
||||
The plugin is a wildcard plugin and can thus be used to retrieve different
|
||||
values depending on the name of the file.
|
||||
|
||||
Linking it as snmp_10.8.1.230_areca_fan would retrieve the fan speed values from
|
||||
the Areca controller at 10.8.1.230.
|
||||
|
||||
Valid values are fan, temp and volt.
|
||||
|
||||
Add the following to your /etc/munin/plugin-conf.d/snmp__areca file:
|
||||
|
||||
[snmp_ip.add.re.ss_*]
|
||||
community private
|
||||
version 1
|
||||
|
||||
Then test the plugin by calling the following commands:
|
||||
|
||||
munin-run snmp_10.8.1.230_areca_temp config
|
||||
munin-run snmp_10.8.1.230_areca_temp
|
||||
|
||||
Both commands should output sensible data without failing.
|
||||
|
||||
=head1 INTERPRETATION
|
||||
|
||||
The plugin shows the temperature in Celsius or the fanspeed in rotations per minute.

=head1 NAME
|
||||
|
||||
snmp__thecus_fans - Munin plugin to retrive fanspeed readings from a Thecus
|
||||
NAS device running SNMP.
|
||||
|
||||
=head1 APPLICABLE SYSTEMS
|
||||
|
||||
All Thecus NAS devices which have the third party NETSNMPD module installed.
|
||||
This is available at http://www.fajo.de/main/thecus/modules/netsnmpd
|
||||
|
||||
=head1 CONFIGURATION
|
||||
|
||||
As a rule SNMP plugins need site specific configuration. The default
|
||||
configuration (shown here) will only work on insecure sites/devices.
|
||||
|
||||
[snmp_*]
|
||||
env.version 2
|
||||
env.community public
|
||||
|
||||
In general SNMP is not very secure at all unless you use SNMP version
|
||||
3 which supports authentication and privacy (encryption). But in any
|
||||
case the community string for your devices should not be "public".
|
||||
|
||||
Please see 'perldoc Munin::Plugin::SNMP' for further configuration
|
||||
information.
|
||||
|
||||
=head1 INTERPRETATION
|
||||
|
||||
The plugin reports the current fan speed readings as reported by the thecusIO
|
||||
module.
