Prometheus.ex v1.0.0-alpha5 Prometheus.Buckets
Histogram buckets generators.
Summary
Macros
Default histogram buckets
Creates count buckets, where the lowest bucket has an
upper bound of start and each following bucket’s upper bound is factor
times the previous bucket’s upper bound. The returned list is meant to be
used for the :buckets key of histogram constructors options
Creates count buckets, each width wide, where the lowest
bucket has an upper bound of start. The returned list is meant to be
used for the :buckets key of histogram constructors options

Default histogram buckets:
iex(2)> Prometheus.Buckets.default()
[0.005, 0.01, 0.025, 0.05, 0.1, 0.25, 0.5, 1, 2.5, 5, 10]Please note these buckets are floats so you’ll have to use Prometheus.Metric.Histogram.dobserve/2.
Creates count buckets, where the lowest bucket has an
upper bound of start and each following bucket’s upper bound is factor
times the previous bucket’s upper bound. The returned list is meant to be
used for the :buckets key of histogram constructors options.
The function raises Prometheus.Error.InvalidValue if count is 0 or negative,
if start is 0 or negative, or if factor is less than or equal 1.
Creates count buckets, each width wide, where the lowest

iex(2)> Prometheus.Buckets.linear(10, 5, 6)
[10, 15, 20, 25, 30, 35]The function raises Prometheus.Error.InvalidValue exception if count is zero or negative.
