Method: Gitlab::Metrics::Samplers::BaseSampler#initialize

Defined in:
lib/gitlab/metrics/samplers/base_sampler.rb

#initialize(interval: nil, logger: Logger.new($stdout), warmup: false, **options) ⇒ BaseSampler

interval - The sampling interval in seconds. warmup - When true, takes a single sample eagerly before entering the sampling loop.

This can be useful to ensure that all metrics files exist after `start` returns,
since prometheus-client-mmap creates them lazily upon first access.
