Release 1.12 is made out of 211 pull requests and 22 bug fixes.
The key improvements are:

  • Introducing, the free netdata service for all netdata users
  • High performance plugins with go.d.plugin (data collection orchestrator written in Go)
  • 7 new data collectors and 11 rewrites of existing data collectors for improved performance
  • A new management API for all netdata servers
  • Bind different functions of the netdata APIs to different ports
  • Improved installation and updates is a free service for all netdata users. Currently it replaces the old netdata registry, while providing single sign on with GitHub and Google accounts.

Using we plan to provide the following features:

  • distributed authentication (password protection) for all netdata installations
  • network view for all nodes
  • cross node custom dashboard editor, storage and sharing
  • centralized health monitoring and alarm notifications

and many more.

Bind API functions to different ports

netdata can now bind its API functions to different ports.

The following API functions can be isolated:

  • dashboard for access the dashboard
  • badges for generating badges
  • streaming for receiving streamed metrics from remote netdata servers
  • management for receiving management commands
  • registry for accessing the netdata registry
  • netdata.conf for downloading the current configuration

To bind API functions to different ports, append =function|function|... to the port definition, like this:

   bind to = *:19999=dashboard|netdata.conf *:20000=streaming

The above will bind netdata:

  • on all IPs (*) at port 19999 for dashboard access and access to netdata.conf
  • on all IPs (*) at port 20000 for receiving streamed data from remote netdata servers

Management API

Netdata now has a management API. We plan to provide a full set of configuration commands using this API.

In this release, the management API supports disabling or silencing alarms during maintenance periods.

Anonymous statistics

Anonymous usage information is collected by default and sent to Google Analytics. The statistics calculated from this information will be used for:

  1. Quality assurance, to help us understand if netdata behaves as expected and help us identify repeating issues for certain distributions or environment.

  2. Usage statistics, to help us focus on the parts of netdata that are used the most, or help us identify the extend our development decisions influence the community.

Information is sent to Netdata via two different channels:

  • Google Tag Manager is used when an agent's dashboard is accessed.
  • The script is executed by the Netdata daemon, when Netdata starts, stops cleanly, or fails.

Both methods are controlled via the same opt-out mechanism.

Data collection

This release introduces a new Go plugin orchestrator. This plugin has its own github repo. It is open-source, using the same license and we welcome contributions. The orchestrator can also be used to build custom data collection plugins written in Go. We have used the orchestrator to write many new Go plugins in our go.d plugin github repo. For more information, check this.

New data collectors:

  • Activemq (Go)
  • Consul (Go)
  • Lighttpd2 (Go)
  • Solr (Go)
  • Springboot2 (Go)
  • mdstat - nonredundant arrays (C)
  • CUPS printing system (C)

High performance versions of older data collectors:

  • apache (Go)
  • dns_query (Go)
  • Freeradius (Go)
  • Httpcheck (Go)
  • Lighttpd (Go)
  • Portcheck (Go)
  • Nginx (Go)
  • cpufreq (C)
  • cpuidle (C)
  • mdstat (C)
  • power supply (C)

Other improved data collectors:

  • Fix the python plugin clock (collectors falling behind).
  • adaptec_raid: add to python.d.conf.
  • apcupsd: Detect if UPS is online.
  • apps: Fix process statistics collection for FreeBSD.
  • apps: Properly lookup docker container name when running in ECS.
