Breaking changes

Linux node_cpu metrics now break out guest values into separate metrics. See Issue #737

v0.15.0 / 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  • The collector selection flag has been replaced by individual boolean flags.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.
