Metrics

The values a MooseFS cluster reports about itself. Every metric name starts with mfs_. The exporter prints the explanation of each name below in the # HELP line of that metric, with its unit in brackets. Prometheus metrics covers how to scrape these metrics. The sections say which part of the cluster a metric describes.
