module ActiveMetrics ## # Custom metrics for Librato module Instrumentable # Count log lines are used to submit increments to Librato. # # You can submit increments as frequently as desired and every minute the # current total will be flushed to Librato and reset to zero. # # @param event [String] The name of the event # @param number [Integer] The number to increment the current count (defaults to 1) def count(event, number = 1) ActiveMetrics::Collector.record(event, { metric: 'count', value: number }) end # Measure log lines are used to submit individual measurements that comprise # a statistical distribution. The most common use case are timings i.e. # latency measurements, but it can also be used to represent non-temporal # distributions such as counts. # # You can submit as many measures as you’d like (typically they are # submitted per-request) and every minute Librato will calculate/record a # complete set of summary statistics over the measures submitted in that # interval. # # @param event [String] The name of the event # @param value [Integer, String] The value measured. def measure(event, value = 0) ActiveMetrics::Collector.record(event, { metric: 'measure', value: value }) end # Sample metrics are used to convey simple key/numerical value pairs when # you are already calculating some kind of summary statistic in your app and # merely need a simple transport mechanism to Librato. # # Typically you would submit sample metrics on some periodic tick and set # said period on the metric in Librato. # # @param key [String] The name of the sample # @param value [Object] The value of the sample def sample(key, value) ActiveMetrics::Collector.record(key, { metric: 'sample', value: value }) end end end
