About

The snmp__areca_ plugin allows the munin monitor to graph the hardware sensors of a 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.

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
  2. Copy or link the snmpareca_ 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.
  3. Configure the munin-node to run the snmpareca_ plugin with the correct snmp community string: 
    [snmp_192.168.1.100*]
community private
version 1
  4. 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.
