    10 ## Description
       
    11 
       
    12 Arborist is a monitoring toolkit that follows the UNIX philosophy
       
    13 of small parts and loose coupling for stability, reliability, and
       
    14 customizability.
       
    15 
       
    16 This adds SNMP support to Arborist's monitoring, for things such as:
       
    17 
       
    18  - Disk space capacity
       
    19  - System load
       
    20  - Free memory
       
    21  - Swap in use
       
    22  - Running process checks

    25 ## Prerequisites
       
    26 
       
    27 * Ruby 2.2 or better
       
    28 
       
    29 
       
    30 ## Installation
       
    31 
       
    32     $ gem install arborist-snmp
       
    33 
       
    34 
       
    35 ## Usage
       
    36 
       
    37 In this example, we've created a resource node under an existing host, like so:
       
    38 
       
    39 	Arborist::Host( 'example' ) do
       
    40 		description "Example host"
       
    41 		address     '10.6.0.169'
       
    42 		resource 'load', description: 'machine load'
       
    43 	end
       
    44 
       
    45 
       
    46 From a monitor file, require this library, and create an snmp instance.
       
    47 You can reuse a single instance, or create individual ones per monitor.
       
    48 
       
    49 
       
    50 	require 'arborist/monitor/snmp'
       
    51 
       
    52 	Arborist::Monitor '5 minute load average check' do
       
    53 		every 30.seconds
       
    54 		match type: 'resource', category: 'load'
       
    55 		include_down true
       
    56 		use :addresses
       
    57 
       
    58 		snmp = Arborist::Monitor::SNMP.new( mode: 'load', load_error_at: 10 )
       
    59 		exec( snmp )
       
    60 	end
       
    61 
       
    62 Please see the rdoc for all the mode types and error_at options.
