  • Fixed delta value returning 0 the first time it's called even if there should be 1 second of data
  • Fixed Mac OS X plist to no longer set user/group (bug fix for Unix systems running as specified uid/gid is related)
  • Fixed processor type not showing up on all Linux distros on GUI dashboard
  • Fixed issue with relative plugin paths on Linux systems when they are built

Deprecated

  • Both API endoints api/service/<servicename> and api/process/<processname> will be removed in version 2.1.0 and should be replaced by api/services?service=<servicename> and api/processes?name=<processname> instead
  • The API endpoint api/agent/plugin/<pluginname> will be removed in version 2.1.0 in favor of api/plugins/<pluginame> which better matches the current API node naming conventions and is a less confusing name
