netdata can generate badges with live information from the collected metrics.

netdata plugins are now written in python!

Thanks to the great work of Paweł Krupa (@paulfantom), most BASH plugins have been ported to python.

The new python.d.plugin supports both python2 and python3 and data collection from multiple sources for all modules.

The following pre-existing modules have been ported to python:

other data collectors

Thanks to @simonnagl netdata now reports disk space usage.

other improvements

    The settings transferred are the dashboard theme, the online help status and current pan and zoom timeframe of the dashboard.

  • API improvements:

    • reduction functions now support 'min', 'sum' and 'incremental-sum'.
    • netdata now offers a multi-threaded and a single threaded web server (single threaded is better for IoT).
  • apps.plugin improvements:

    • can now run with command line argument 'without-files' to prevent it from enumating all the open files/sockets/pipes of all running processes.
    • apps.plugin now scales the collected values to match the
      the total system usage.
    • apps.plugin can now report guest CPU usage per process.
    • repeating errors are now logged once per process.
  • netdata now runs with IDLE process priority (lower than nice 19)

  • netdata now instructs the kernel to kill it first when it starves for memory.

  • netdata listens for signals:

    • SIGHUP to netdata instructs it to re-open its log files (new logrotate file added too).
    • SIGUSR1 to netdata saves the database
    • SIGUSR2 to netdata reloads health / alarms configuration
  • netdata can now bind to multiple IPs and ports.

  • netdata now has new systemd service file (it starts as user netdata and does not fork).

  2. netdata now has a registry (my-netdata dashboard menu) !
  3. netdata now monitors Linux Containers (cgroups, docker, lxc, etc) !

IMPORTANT:

  • uuid-dev (debian/ubuntu), or
  • libuuid-devel (centos/fedora/redhat)

In detail

netdata is now 30% faster !

  • Patches submitted by @fredericopissarra improved overall netdata performance by 10%.
  • A new improved search function in the internal indexes made all searches faster by 50%, resulting in about 20% better performance for the core of netdata.
  • More efficient threads locking in key components contributed to the overall speed up.

netdata now has a central registry !

The central registry tracks all your netdata servers and bookmarks them for you at the my-netdata menu on all dashboards.

Every netdata can act as a registry, but there is also a global registry provided for free for all netdata users!

netdata now monitors Linux Containers !

docker, lxc, or anything else. For each container it monitors CPU, RAM, DISK I/O (network interfaces were already monitored).

Other improvements

  • apps.plugin: now uses linux capabilities by default without setuid to root
  • netdata has now an improved signal handler thanks to @simonnagl
  • API: new improved CORS support
  • SNMP: counter64 support fixed
  • MYSQL: more charts, about QCache, MyISAM key cache, InnoDB buffer pools, open files
  • DISK charts now show mount point when available
  • Dashboard: improved support for older web browsers and mobile web browsers (thanks to @simonnagl)
  • Multi-server dashboards now allow de-coupled refreshes for each chart, so that if one netdata has a network latency the other charts are not affected
  • Dozens of other improvements, optimizations and bug-fixes.
