Installs and configures snmpd. Optionally install SNMP utilities, such as snmpwalk.
The SNMP multiplex (smuxpeer) line will be set for Dell OpenManage, if Dell manufactured hardware is detected by Ohai.
This cookbook provides an SNMP Extend example to collect DNS RNDC statistics (disabled DNS). 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, remove the "depends perl" line from metadata.rb. Then run 'knife cookbook metadata snmp' before uploading to the Chef server.
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[:install_optional]
- Boolean to install optional SNMP utilities, default is false.
-
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.
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,
"install_optional" => true,
"trapsinks" => [ "zenoss.example.com", "nagios.example.com" ],
"syslocationPhysical" => "Server Room",
"syslocationVirtual" => "Cloud - Virtual Pool",
"syscontact" => "sysadmin@example.com"
}
