Best talks day 1:

  • Please, no More Minutes, Milliseconds, Monoliths... or Monitoring Tools! - Adrian Cockcroft
    • gave 5 good rules for monitoring systems, showed what cloud / microservices monitoring looks like @ Netflix
  • Simple math to get some signal out of your noisy sea of data - Toufic Boubez
  • explains why static alert thresholds don't work and gave 3 techniques to use instead
# you can make a text file of request times (in ms, one number per line) and import it here, or you can use a probability distribution to simulate request times (see below where setting req_durations_in_ms)
# rq = read.table("~/Downloads/request_times.txt", header=FALSE)$V1
# argument notes:
# parallel_router_count is only relevant if router_mode is set to "intelligent"
# choice_of_two, power_of_two, and unicorn_workers_per_dyno are only relevant if router_mode is set to "naive"
# you can only select one of choice_of_two, power_of_two, and unicorn_workers_per_dyno
run_simulation = function(router_mode = "naive",
reqs_per_minute = 9000,
