1) Breaking changes! Updated collection code for proper Prometheus support - Now metrics names of all subcollectors have prefixes: nsq_topic_, nsq_channel_, nsq_client_ As a result metrics registration code now passing Prometheus' client validation, also it fixes scrape warnings - "type" label in exported metrics removed as obsolete 2) Add reset of gauges before scrape (like in haproxy-exporter) 3) Refactor: subcollectors logic is simplified, multiple collectors support removed We always use 'stats' collector so it removes unnecessary flexibility and complexity.
