DESCRIPTION

Installs and configures snmpd.

The SNMP multiplex (smuxpeer) line will be set for Dell OpenManage, if Dell manufactured hardware is detected by Ohai.

REQUIREMENTS

This cookbook provides an SNMP Extend example to collect DNS RNDC statistics. The SNMP Extend script is written in Perl and depends on the CPAN module "version", and Getopt::Declare.

There is a loose dependency recommending the "perl" cookbook. If you have no need for the SNMP Extend example included, you may remove the "depends perl" line from metadata.rb. Then run 'knife cookbook metadata snmp' before uploading to the Chef server.

RECIPES

• snmp::default

  • Installs and configures SNMP

• snmp::extendbind

  • Example recipe to deploy a Perl based extend script to collect stats from a BIND 9 server.

ATTRIBUTES

Notable overridable attributes are as follows. It is recommended to override these following attributes to best suit your own environment.

• snmp[:community]

  • SNMP Community String, default is "public".

• snmp[:trapcommunity]

  • SNMP Community Trap String, default is "public".

• snmp[:trapsinks]

  • Array of trapsink hosts, and optionall Community Trap strings. This is an empty array by default.

• snmp[:syscontact]

  • String to set a name, and e-mail address for systems. Default is "Root root@localhost"

• snmp[:syslocationPhysical]

  • String to set the location for physical systems. Default is "Server Room".

• snmp[:syslocationVirtual]

  • String to set the location for Virtual Machines. Default is "Virtual Server".

• snmp[:full_systemview]

  • Boolean to include the full systemview. This defaults to "false" as many distributions ship this way to speed up snmpwalk. However, if you're running SNMP Network Management System, you'll want to override this as "true" on your systems.

USAGE

Here is a full example featuring all the overridable attributes. You can apply these override attributes in a role, or node context.

  override_attributes "snmp" => {
    "community" => "secret",
    "full_systemview" => true,
    "trapsinks" => [ "zenoss.example.com", "nagios.example.com" ],
    "syslocationPhysical" => "Server Room",
    "syslocationVirtual" => "Cloud - Virtual Pool",
    "syscontact" => "sysadmin@example.com"
  }
