= ARECA Raid controller sensor statistics =

== About ==
The [source:snmp__areca_] plugin allows the [http://munin.projects.linpro.no/ munin] monitor to graph the hardware sensors of a [http://www.areca.com.tw ARECA] RAID controller. The plugin is able to retrieve the temperatures, the fan speeds and the voltages exported by the ARECA controller via it's SNMP management interface.

== Download ==
[https://trac.bawue.org/munin/browser/snmp_areca_?format=txt snmp__areca_]

== Installation ==
  1. Make sure the areca controller is accessible via SNMP. A test might be performed by calling {{{snmpwalk -v 1 -c snmp_community ip.add.re.ss}}}
  1. Copy or link the snmp__areca_ script into your munin-node plugin directory, usually {{{/etc/munin/plugins}}}. The areca script is a wildcard plugin and should therefore be linked as e.g. {{{snmp_192.168.1.100_areca_fan}}}, {{{snmp_192.168.1.100_areca_temp}}} and {{{snmp_192.168.1.100_areca_volt}}}. Adapt the IP address accordingly to the local setup.
  1. Configure the munin-node to run the snmp__areca_ plugin with the correct snmp community string:
{{{
[snmp_192.168.1.100*]
community private
version 1
}}}
  1. Test the plugin by calling {{{munin-run snmp_192.168.1.100_areca_temp config}}} and by executing {{{munin-run snmp_192.168.1.100_areca_temp}}}. Both commands should output sensible data without failing.

== Notes ==
  * This plugin unfortunately is not able to correctly autoconfigure itself.
