other improvements

  • dashboards now transfer certain settings from server to server when changing servers via the my-netdata menu.

    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).

  • Dozens of other improvements and bugfixes
