# Simple library to aid in tracking statistics regarding Kthxbye and its workers.
# Submits jobs processed stats, total failures, total uptime, etc.
# Puts all stats in stats:x vars in Redis. Super flexible, made to allow tracking
# of any kind of count internally
#
# Built in stats (tracked by Kthxbye internals) include the following
#
#  processed - the count of processed jobs
#  <worker>:processed - the count a given worker has processed
#  failures - the count of failed jobs

module Kthxbye
  module Stats
    extend self
    extend Helper

    # get count for a given stat (can also use [] method)
    def get( stat )
      redis.get( "stat:#{stat}" ).to_i
    end
    alias_method :[], :get

    # increment a count by a given value (defaults to 1)
    def incr( stat, by=1 )
      redis.incrby("stat:#{stat}", by)
    end

    # decrement a count by a given value (defaults to 1)
    def decr( stat, by=1 )
      redis.decrby("stat:#{stat}", by)
    end

    # reset this stat to 0
    def reset( stat )
      redis.del( "stat:#{stat}" )
    end

  end
