In this talk, Bethany Erskine, Devops Engineer from Paperless Post, presents an in-depth look into why Paperless Post chose Sensu, and how they monitor their services and collect system metrics to send to Graphite. Subtopics will include how we planned for and executed the migration, mistakes they made along the way, how they knew when to scale and how they did scale. Bethany also covers how Paperless Post is making their Sensu setup redundant and highly available, and how they're monitoring and collecting metrics about Sensu and integrating their internal tools with it. This talk was recorded at the NYC Devops meetup at Meetup HQ.
