node_exporter 1.0.0

[Ben Kochie]

After 7 years of development, with contributions from 100 people, we've reached the 1.0 status for the node_exporter.

From now on, we will keep metric and label names stable between major versions.

The 1.0.0 release also introduces new security features. TLS for security and authentication, and HTTP basic authentication.

The full list of changes is below:

Breaking changes

• The netdev collector CLI argument --collector.netdev.ignored-devices was renamed to --collector.netdev.device-blacklist in order to conform with the systemd collector. #1279
• The label named state on node_systemd_service_restart_total metrics was changed to name to better describe the metric. #1393
• Refactoring of the mdadm collector changes several metrics
  • node_md_disks_active is removed
  • node_md_disks now has a state label for "fail", "spare", "active" disks.
  • node_md_is_active is replaced by node_md_state with a state set of "active", "inactive", "recovering", "resync".
• Additional label mountaddr added to NFS device metrics to distinguish mounts from the same URL, but different IP addresses. #1417
• Metrics node_cpu_scaling_frequency_min_hrts and node_cpu_scaling_frequency_max_hrts of the cpufreq collector were renamed to node_cpu_scaling_frequency_min_hertz and node_cpu_scaling_frequency_max_hertz. #1510
• Collectors that are enabled, but are unable to find data to collect, now return 0 for node_scrape_collector_success.
