SNMP::Open

Gem Version Build Status

Ruby wrapper for the Net-SNMP command line programs snmpget, snmpwalk, and snmpbulkwalk.

Installation

Add this line to your application's Gemfile:

gem 'snmp-open'

And then execute:

$ bundle

Or install it yourself as:

$ gem install snmp-open

Usage

The API is very loosely based on that of the snmp gem. SNMP::Open supports #get and #walk methods, which map to snmpget and snmpbulkwalk. These commands must be installed and available in the path.

Short command-line flags understood by snmpcmd(1) can be passed to the constructor directly:

snmp = SNMP::Open.new(host: 'example1', '-v' => '2c', '-c' => ENV['COMMUNITY'])
snmp.walk(['1.3.6.1.2.1.47.1.1.1.1.7', '1.3.6.1.2.1.2.2.1.2']) do |name, descr|
  puts "Interface Name: #{name.value}, Description: #{descr.value}"
end

Naturally, configuration can also be supplied through snmp.conf(5).

Environment variables can be given using the env keyword parameter to SNMP::Open.new. For example, the SNMP_PERSISTENT_FILE and SNMPCONFPATH variables are understood by Net-SNMP commands and indicate paths in which to look for configuration files.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
