5 Lines I Couldn't Draw

This talk was super inspiring. I strongly suggest watching a video when posted.

Link to livestream, starting at this talk: https://www.youtube.com/watch?v=vQBtun-Ein8&index=2&list=PLGJrMkJUF3M3Vi_vgDiyBpWsOP41XzJnM&t=303m5s

  • "Wow. that sounds awful"
  • "Its fine"
  • "alert on the derivative of the message volume per sec"
  • now emails are not alerts, they're signal.
  • Cognitive leap of monitoring tools as signal for state of the system
  • one of 5 lines.
  • I was carrying a misapprehension about what monitoring was and whom it was for
  • "Monitoring is the thing that makes alerts happen" is a fallacy ###
  • Always an ad-hoc, and prescriptive in the wrong direction.
  • "Monitoring is not FOR alerting". Not about uptime.
  • "Nobody OWNS monitoring"
  • "Everyone owns monitoring"
  • "Everyone can measure things... Everyone who cares, gets to measure"
  • Success because expectations change.
  • "What if I told you: You might be fascinated with anomaly detection because your input signal sucks"
  • Complexity isolates. Those alerts are the sword ops dies on. So don't.
  • Rate limiting - Post: There is no data available at this time interval
    • Librato limits metrics ingest to save bill of customer.
  • Cynefin Chaotic -> Complex -> Complicated -> obvious --->
    • Things you need to move:
      • Control
      • understanding
      • standardization
  • "I thought complexity was my lot of life" Me dissecting somebody's JS circa 2003.
  • Pain of ops isolates ops from larger world.
  • Work to reduce complexity... and monitoring helps simplify.
    • helps you find the 1-3 metrics you actually care about.
  • Person who curated the view of awesome isn't the person who collected the metrics.
  • Other people help you build the bridge to understanding
  • Teams need to share metrics. Publish them internally.
  • "Everyone gets to measure things, no one owns monitoring"
  • "I was alone with my pain, despite being surrounded by engineers"
  • "Someone else's problem" does not exist
  • "Effective Telemetry + people measuring things = better culture"
  • They want to comprehend the Y-Axis of your win.
