0.16.0 / 2018-05-15

Breaking changes

This release contains major breaking changes to metric names. Many metrics have new names, labels, and label values in order to conform to current naming conventions.

  • Linux node_cpu metrics now break out guest values into separate metrics. See Issue #737
  • Many counter metrics have been renamed to include _total.
  • Many metrics have been renamed/modified to include base units, for example node_cpu is now node_cpu_seconds_total.

In order to help with the transition we have an upgrade guide.

0.15.0 / 2017-10-06

Breaking changes

This release contains major breaking changes to flag handling.

  • The flag library has been changed, all flags now require double-dashs. (-foo becomes --foo).
  • The collector selection flag has been replaced by individual boolean flags.
  • The -collector.procfs and -collector.sysfs flags have been renamed to --path.procfs and --path.sysfs respectively.

The ntp collector has been replaced with a new NTP-based check that is designed to expose the state of a localhost NTP server rather than provide the offset of the node to a remote NTP server. By default the ntp collector is now locked to localhost. This is to avoid accidental spamming of public internet NTP pools.

Windows support is now removed, the wmi_exporter is recommended as a replacement.
