  43. 43. Enough!
  44. 44. What did we try? ● A monitoring system framework ● A monitoring framework / An open source monitoring framework ● The monitoring router ● Agile monitoring ● The feedback loop for infrastructure as code development workflows ● Full stack monitoring for dynamic operating environments ● Monitoring for today's business ● An artform, apparently? ● A robust monitoring system ● Total visibility from bare metal to Kubernetes
  45. 45. What did didn't we try? ● A monitoring system framework ● A monitoring framework / An open source monitoring framework ● The monitoring router ● Agile monitoring ● The feedback loop for infrastructure as code development workflows ● Full stack monitoring for dynamic operating environments ● Monitoring for today's business ● An artform, apparently? ● A robust monitoring system ● Total visibility from bare metal to Kubernetes
  46. 46. ● Calling Sensu a framework wasn't wrong, it just wasn't compelling beyond a certain audience ● A framework infers raw materials, no true identity ● It literally includes the word "work". We are lazy! ● No mention of the benefits! It turns out, words are really hard!
  47. 47. What is Sensu?
  48. 48. How does Sensu empower users?
  49. 49. Workflow automation for monitoring. (this is how Sensu users are empowered)
  50. 50. Sensu is a monitoring event pipeline. (this is the secret sauce)
  51. 51. Simple building blocks, limitless possibilities.
  52. 52. A monitoring event pipeline as unique as your business.
  53. 53. Monitoring events: a simple abstraction for discovery, availability, telemetry, and alerts. { "source": "web-server-01", "name": "web_service", "environment": "production", "region": "us-west-1", "status": 2, "output": "HTTP/1.1 404 Not Found", "handlers": ["pagerduty","influxdb"], "contacts": ["web_team"] }
  54. 54. The Sensu client/agent is a powerful event producer.
  55. 55. Is this just "marketing 101"?
  56. 56. How does this benefit Sensu users?
  57. 57. "We gotta find a way to make [this] fit into the hole for (this), using nothing but {that}."
  58. 58. Legacy instrumentation (Nagios plugins) ⇒ modern tools (InfluxDB)?? Legacy systems (SNMP) ⇒ modern tools (InfluxDB)?? Modern systems (ephemeral compute) ⇒ legacy tools (Nagios, Tivoli)?? Modern systems (Kubernetes) ⇒ enterprise tools (ServiceNow)?? Square pegs / round holes
  59. 59. "We gotta find a way to make [this] fit into the hole for (this), using nothing but {that}."
  60. 60. Hybrid cloud monitoring becomes a lot easier to reason about when everything is a "workflow"
  61. 61. ● Nagios replacement ● Monitoring ephemeral infrastructure (hybrid cloud, containers) ● Automated remediation (shhh… don't tell Sean) ● Automated CMDB registration (ServiceNow) ● Automated compliance monitoring (inspec, osquery) ● Enterprise monitoring governance Example workflows
  62. 62. Let's play a game!
  63. 63. Monitoring workflow mad libs! My team, ___(insert name of team)___, needs to know when ___(a type of monitoring event occurs)___ to improve ___(a specific customer experience)___ by ___(automating a workflow)___ with ___(existing tools or systems)___.
  64. 64. Call To Action ● Forget everything you know about Sensu ● How does reimagining Sensu as workflow automation for monitoring impact you? ● Embrace the monitoring event pipeline ● Tell a friend! ● Share your stories with us!
  65. 65. Thank you!!!
