Infrastructure as Code & Monitoring Sharing the same development workflow.
Sean Porter @PorterTech
FOCUS • The Sensu origin story - where it came
from • What makes Sensu different • IaC development workflows • Testing & monitoring in an IaC workflow • Chef & Sensu in practice
None
THE SENSU ORIGIN STORY • I started at Sonian ~
2010 ◦ Chef 0.7 with AWS #YOLO infrastructure ◦ Several traditional monitoring tools: Nagios, Ganglia, Collectd, & Graphite
~ 50 alerts a day Mostly noise.
THE SENSU ORIGIN STORY Triggered @lusis to write: “Why Monitoring
Sucks”
Wanted MOAR!
Build it. Automatic (de)registration Config Management friendly Secure connectivity REST

What makes Sensu different? What makes it better for CM
driven environments?
None
JSON CONFIGURATION { "checks": { "mysql_replication": { "command": "check-mysql-replication.rb", "subscribers":
["mysql"], "interval": 30, "playbook": "http://wiki.example.com/mysql-replication-playbook" } } }
CHECK EXECUTION METHODS • Pub/Sub (central orchestration) ◦ e.g. execute
http check on all API nodes • Standalone ◦ Define checks while provisioning node(s) ◦ Scheduled by the local Sensu client
LOCAL CLIENT SOCKET echo '{ \ "name": "mysql_backup", \ "output":
"could not connect to mysql", \ "status": 2, \ "ttl": 90000 }' | nc localhost 3030

Let’s talk about IaC workflows “The sequence of processes through
which a piece of work passes from initiation to completion” - Google.
BASIC IaC WORKFLOW “It’s all software.”
BASIC IaC WORKFLOW
BASIC IaC WORKFLOW “It’s all software.”
BASIC IaC WORKFLOW Use tests. Still need to review tests
& code quality.
BASIC IaC WORKFLOW TEST ≈ MONITOR
BASIC IaC WORKFLOW Shorten the feedback loop.
Writing IaC tests “A procedure intended to establish the quality,
performance, or reliability of something, especially before it is taken into widespread use” - Google.
TESTING TOOLS • Serverspec ◦ RSpec tests for your servers
◦ serverspec.org • Bats ◦ Bash Automated Testing System ◦ Bash script with special syntax for defining test cases
SERVERSPEC require 'spec_helper' describe service('httpd'), :if => os[:family] == 'redhat'
do it { should be_enabled } it { should be_running } end describe port(80) do it { should be_listening } end
BATS #!/usr/bin/env bats @test "httpd should be running" { run
service httpd status [ "$status" -eq 0 ] } @test "httpd should be listening for connections" { [ "$(netstat -plant | grep httpd)" ] }
RUNNING TESTS • Test Kitchen ◦ kitchen.ci • Vagrant plugins
◦ github.com/jvoorhis/vagrant-serverspec • Serverspec SSH • … choose your own adventure!
RUNNING TESTS AS SENSU CHECKS • Use the Sensu Serverspec
check plugin ◦ gem install sensu-plugins-serverspec check-serverspec.rb \ -d /etc/sensu/serverspec -t '*_spec.rb' • Run Bats scripts
Chef & Sensu In practice.
SENSU CHEF COOKBOOK supermarket.chef.io/cookbooks/sensu • Recipes to install & manage
services • LWRPs for configuring handlers, checks, etc. • Intended to be used by wrapper cookbook ◦ e.g. recipe['monitor::haproxy']
EXAMPLE CHEF RESOURCES sensu_handler 'default' do # recipe['monitor::_handlers'] type 'pipe'
command 'pagerduty.rb' end sensu_check 'redis_process' do # recipe['monitor::redis'] command 'check-procs.rb -p redis-server -w 2 -c 3 -C 1' standalone true interval 30 end
USING DATA BAGS # recipe['monitor::pubsub'] data_bag('sensu_checks').each do |data_bag_item| check =
data_bag_item('sensu_checks', data_bag_item) sensu_check check['id'] do check.each do |key, value| send(key.to_sym, value) if respond_to?(key.to_sym) end end end
SENSU SERVERSPEC CHECKS # recipe['monitor::serverspec'] sensu_gem 'sensu-plugins-serverspec' sensu_check 'serverspec' do
command 'check-serverspec.rb -d /etc/sensu/serverspec -t \*_spec.rb ' standalone true interval 30 end # e.g. CheckServerspec CRITICAL: 12 examples, 2 failures
BASIC IaC WORKFLOW TEST ≈ MONITOR
